+This file contains basic information on the port of U-Boot to IPHASE4539
+(Interphase 4539 T1/E1/J1 PMC Communications Controller).
+All the changes fit in the common U-Boot infrastructure, providing a new
+IPHASE4539-specific entry in makefiles. To build U-Boot for IPHASE4539,
+type "make IPHASE4539_config", edit the "include/config_IPHASE4539.h"
+file if necessary, then type "make".
+
+
+Common file modifications:
+--------------------------
+
+The following common files have been modified by this project:
+(starting from the ppcboot-1.1.5/ directory)
+
+MAKEALL				- IPHASE4539 entry added
+Makefile			- IPHASE4539_config entry added
+
+
+New files:

+The following new files have been added by this project:
+(starting from the ppcboot-1.1.5/ directory)
+
+board/iphase4539/		- board-specific directory
+board/iphase4539/Makefile	- board-specific makefile
+board/iphase4539/config.mk	- config file
+board/iphase4539/flash.c	- flash driver (for AM29LV033C)
+board/iphase4539/ppcboot.lds	- linker script
+board/iphase4539/iphase4539.c	- ioport and memory initialization
+include/config_IPHASE4539.h	- main configuration file
+
+
+New configuration options:
+--------------------------
+
+CONFIG_IPHASE4539
+
+	Main board-specific option (should be defined for IPHASE4539).
+
+
+Acceptance criteria tests:
+--------------------------
+
+The following tests have been conducted to validate the port of U-Boot
+to IPHASE4539:
+
+1. Operation on serial console:
+
+With SMC1 defined as console in the main configuration file, the U-Boot
+output appeared on the serial terminal connected to the 2.5mm stereo jack
+connector as follows:
+

+
+Using the Motorola MPC8XXFADS development board
+===============================================
+
+CONFIGURATIONS
+--------------
+
+There are ready-to-use default configurations available for the
+FADS823, FADS850SAR and FADS860T. The FADS860T configuration also
+works for the 855T processor.
+
+LOADING U-Boot INTO FADS FLASH MEMORY
+--------------------------------------
+
+MPC8BUG can load U-Boot into the FLASH memory using LOADF.
+
+    loadf u-boot.srec 100000
+
+
+STARTING U-Boot FROM MPC8BUG
+-----------------------------
+
+To start U-Boot from MPC8BUG:
+
+1. Reset the board:
+    reset :h
+
+2. Change BR0 and OR0 back to their values at reset:
+    rms memc br0 00000001
+    rms memc or0 00000d34
+
+3. Modify DER so MPC8BUG gets control only when it should:
+    rms der 2002000f
+
+4. Start as if from reset:
+    go 100
+
+This is NOT exactly the same as starting U-Boot without
+MPC8BUG. MPC8BUG turns off the watchdog as part of the hard reset.
+After it does the reset it writes SYPCR (to disable the watchdog)
+and sets BR0 and OR0 to map the FLASH at 0x02800000 (and does lots
+of other initialization). That is why it is necessary to set BR0
+and OR0 to map the FLASH everywhere. U-Boot can't turn on the
+watchdog after that, since MPC8BUG has used the only chance to write
+to SYPCR.
+
+Here is a bizarre sequence of MPC8BUG and U-Boot commands that lets
+U-Boot write to SYPCR. It works with MPC8BUG 1.5 and an 855T
+processor (your mileage may vary). It is probably better (and a lot
+easier) just to accept having the watchdog disabled when the debug
+cable is connected.
+
+in MPC8BUG:
+  reset :h
+  rms memc br0 00000001
+  rms memc or0 00000d34
+  rms der 2000f
+  go 100
+
+Now U-Boot is running with the MPC8BUG value for SYPCR. Use the
+U-Boot 'reset' command to reset the board.
+  =>reset
+Next, in MPC8BUG:
+  rms der 2000f
+  go
+
+Now U-Boot is running with the U-Boot value for SYPCR.

+ * Image Types
+ *
+ * "Standalone Programs" are directly runnable in the environment
+ *	provided by U-Boot; it is expected that (if they behave
+ *	well) you can continue to work in U-Boot after return from
+ *	the Standalone Program.
+ * "OS Kernel Images" are usually images of some Embedded OS which
+ *	will take over control completely. Usually these programs
+ *	will install their own set of exception handlers, device
+ *	drivers, set up the MMU, etc. - this means, that you cannot
+ *	expect to re-enter U-Boot except by resetting the CPU.
+ * "RAMDisk Images" are more or less just data blocks, and their
+ *	parameters (address, size) are passed to an OS kernel that is
+ *	being started.
+ * "Multi-File Images" contain several images, typically an OS
+ *	(Linux) kernel image and one or more data images like
+ *	RAMDisks. This construct is useful for instance when you want
+ *	to boot over the network using BOOTP etc., where the boot
+ *	server provides just a single image file, but you want to get
+ *	for instance an OS kernel and a RAMDisk image.
+ *
+ *	"Multi-File Images" start with a list of image sizes, each
+ *	image size (in bytes) specified by an "uint32_t" in network
+ *	byte order. This list is terminated by an "(uint32_t)0".
+ *	Immediately after the terminating 0 follow the images, one by
+ *	one, all aligned on "uint32_t" boundaries (size rounded up to
+ *	a multiple of 4 bytes).
+ *
+ * "Firmware Images" are binary images containing firmware (like
+ *	U-Boot or FPGA images) which usually will be programmed to
+ *	flash memory.
+ *
+ * "Script files" are command sequences that will be executed by
+ *	U-Boot's command interpreter; this feature is especially
+ *	useful when you configure U-Boot to use a real shell (hush)
+ *	as command interpreter.

+  A version of malloc/free/realloc written by Doug Lea and released to the
+  public domain.  Send questions/comments/complaints/performance data
+  to dl@cs.oswego.edu
+
+* VERSION 2.6.6  Sun Mar  5 19:10:03 2000  Doug Lea  (dl at gee)
+
+   Note: There may be an updated version of this malloc obtainable at
+           ftp://g.oswego.edu/pub/misc/malloc.c
+         Check before installing!
+
+* Why use this malloc?
+
+  This is not the fastest, most space-conserving, most portable, or
+  most tunable malloc ever written. However it is among the fastest
+  while also being among the most space-conserving, portable and tunable.
+  Consistent balance across these factors results in a good general-purpose
+  allocator. For a high-level description, see
+     http://g.oswego.edu/dl/html/malloc.html
+
+* Synopsis of public routines
+
+  (Much fuller descriptions are contained in the program documentation below.)
+
+  malloc(size_t n);
+     Return a pointer to a newly allocated chunk of at least n bytes, or null
+     if no space is available.
+  free(Void_t* p);
+     Release the chunk of memory pointed to by p, or no effect if p is null.
+  realloc(Void_t* p, size_t n);
+     Return a pointer to a chunk of size n that contains the same data
+     as does chunk p up to the minimum of (n, p's size) bytes, or null
+     if no space is available. The returned pointer may or may not be
+     the same as p. If p is null, equivalent to malloc.  Unless the
+     #define REALLOC_ZERO_BYTES_FREES below is set, realloc with a
+     size argument of zero (re)allocates a minimum-sized chunk.
+  memalign(size_t alignment, size_t n);
+     Return a pointer to a newly allocated chunk of n bytes, aligned
+     in accord with the alignment argument, which must be a power of
+     two.
+  valloc(size_t n);
+     Equivalent to memalign(pagesize, n), where pagesize is the page
+     size of the system (or as near to this as can be figured out from
+     all the includes/defines below.)
+  pvalloc(size_t n);
+     Equivalent to valloc(minimum-page-that-holds(n)), that is,
+     round up n to nearest pagesize.
+  calloc(size_t unit, size_t quantity);
+     Returns a pointer to quantity * unit bytes, with all locations
+     set to zero.
+  cfree(Void_t* p);
+     Equivalent to free(p).
+  malloc_trim(size_t pad);
+     Release all but pad bytes of freed top-most memory back
+     to the system. Return 1 if successful, else 0.
+  malloc_usable_size(Void_t* p);
+     Report the number usable allocated bytes associated with allocated
+     chunk p. This may or may not report more bytes than were requested,
+     due to alignment and minimum size constraints.
+  malloc_stats();
+     Prints brief summary statistics on stderr.
+  mallinfo()
+     Returns (by copy) a struct containing various summary statistics.
+  mallopt(int parameter_number, int parameter_value)
+     Changes one of the tunable parameters described below. Returns
+     1 if successful in changing the parameter, else 0.
+
+* Vital statistics:
+
+  Alignment:                            8-byte
+       8 byte alignment is currently hardwired into the design.  This
+       seems to suffice for all current machines and C compilers.
+
+  Assumed pointer representation:       4 or 8 bytes
+       Code for 8-byte pointers is untested by me but has worked
+       reliably by Wolfram Gloger, who contributed most of the
+       changes supporting this.
+
+  Assumed size_t  representation:       4 or 8 bytes
+       Note that size_t is allowed to be 4 bytes even if pointers are 8.
+
+  Minimum overhead per allocated chunk: 4 or 8 bytes
+       Each malloced chunk has a hidden overhead of 4 bytes holding size
+       and status information.
+
+  Minimum allocated size: 4-byte ptrs:  16 bytes    (including 4 overhead)
+                          8-byte ptrs:  24/32 bytes (including, 4/8 overhead)
+
+       When a chunk is freed, 12 (for 4byte ptrs) or 20 (for 8 byte
+       ptrs but 4 byte size) or 24 (for 8/8) additional bytes are
+       needed; 4 (8) for a trailing size field
+       and 8 (16) bytes for free list pointers. Thus, the minimum
+       allocatable size is 16/24/32 bytes.
+
+       Even a request for zero bytes (i.e., malloc(0)) returns a
+       pointer to something of the minimum allocatable size.
+
+  Maximum allocated size: 4-byte size_t: 2^31 -  8 bytes
+                          8-byte size_t: 2^63 - 16 bytes
+
+       It is assumed that (possibly signed) size_t bit values suffice to
+       represent chunk sizes. `Possibly signed' is due to the fact
+       that `size_t' may be defined on a system as either a signed or
+       an unsigned type. To be conservative, values that would appear
+       as negative numbers are avoided.
+       Requests for sizes with a negative sign bit when the request
+       size is treaded as a long will return null.
+
+  Maximum overhead wastage per allocated chunk: normally 15 bytes
+
+       Alignnment demands, plus the minimum allocatable size restriction
+       make the normal worst-case wastage 15 bytes (i.e., up to 15
+       more bytes will be allocated than were requested in malloc), with
+       two exceptions:
+         1. Because requests for zero bytes allocate non-zero space,
+            the worst case wastage for a request of zero bytes is 24 bytes.
+         2. For requests >= mmap_threshold that are serviced via
+            mmap(), the worst case wastage is 8 bytes plus the remainder
+            from a system page (the minimal mmap unit); typically 4096 bytes.
+
+* Limitations
+
+    Here are some features that are NOT currently supported
+
+    * No user-definable hooks for callbacks and the like.
+    * No automated mechanism for fully checking that all accesses
+      to malloced memory stay within their bounds.
+    * No support for compaction.
+
+* Synopsis of compile-time options:
+
+    People have reported using previous versions of this malloc on all
+    versions of Unix, sometimes by tweaking some of the defines
+    below. It has been tested most extensively on Solaris and
+    Linux. It is also reported to work on WIN32 platforms.
+    People have also reported adapting this malloc for use in
+    stand-alone embedded systems.
+
+    The implementation is in straight, hand-tuned ANSI C.  Among other
+    consequences, it uses a lot of macros.  Because of this, to be at
+    all usable, this code should be compiled using an optimizing compiler
+    (for example gcc -O2) that can simplify expressions and control
+    paths.
+
+  __STD_C                  (default: derived from C compiler defines)
+     Nonzero if using ANSI-standard C compiler, a C++ compiler, or
+     a C compiler sufficiently close to ANSI to get away with it.
+  DEBUG                    (default: NOT defined)
+     Define to enable debugging. Adds fairly extensive assertion-based
+     checking to help track down memory errors, but noticeably slows down
+     execution.
+  REALLOC_ZERO_BYTES_FREES (default: NOT defined)
+     Define this if you think that realloc(p, 0) should be equivalent
+     to free(p). Otherwise, since malloc returns a unique pointer for
+     malloc(0), so does realloc(p, 0).
+  HAVE_MEMCPY               (default: defined)
+     Define if you are not otherwise using ANSI STD C, but still
+     have memcpy and memset in your C library and want to use them.
+     Otherwise, simple internal versions are supplied.
+  USE_MEMCPY               (default: 1 if HAVE_MEMCPY is defined, 0 otherwise)
+     Define as 1 if you want the C library versions of memset and
+     memcpy called in realloc and calloc (otherwise macro versions are used).
+     At least on some platforms, the simple macro versions usually
+     outperform libc versions.
+  HAVE_MMAP                 (default: defined as 1)
+     Define to non-zero to optionally make malloc() use mmap() to
+     allocate very large blocks.
+  HAVE_MREMAP                 (default: defined as 0 unless Linux libc set)
+     Define to non-zero to optionally make realloc() use mremap() to
+     reallocate very large blocks.
+  malloc_getpagesize        (default: derived from system #includes)
+     Either a constant or routine call returning the system page size.
+  HAVE_USR_INCLUDE_MALLOC_H (default: NOT defined)
+     Optionally define if you are on a system with a /usr/include/malloc.h
+     that declares struct mallinfo. It is not at all necessary to
+     define this even if you do, but will ensure consistency.
+  INTERNAL_SIZE_T           (default: size_t)
+     Define to a 32-bit type (probably `unsigned int') if you are on a
+     64-bit machine, yet do not want or need to allow malloc requests of
+     greater than 2^31 to be handled. This saves space, especially for
+     very small chunks.
+  INTERNAL_LINUX_C_LIB      (default: NOT defined)
+     Defined only when compiled as part of Linux libc.
+     Also note that there is some odd internal name-mangling via defines
+     (for example, internally, `malloc' is named `mALLOc') needed
+     when compiling in this case. These look funny but don't otherwise
+     affect anything.
+  WIN32                     (default: undefined)
+     Define this on MS win (95, nt) platforms to compile in sbrk emulation.
+  LACKS_UNISTD_H            (default: undefined if not WIN32)
+     Define this if your system does not have a <unistd.h>.
+  LACKS_SYS_PARAM_H         (default: undefined if not WIN32)
+     Define this if your system does not have a <sys/param.h>.
+  MORECORE                  (default: sbrk)
+     The name of the routine to call to obtain more memory from the system.
+  MORECORE_FAILURE          (default: -1)
+     The value returned upon failure of MORECORE.
+  MORECORE_CLEARS           (default 1)
+     True (1) if the routine mapped to MORECORE zeroes out memory (which
+     holds for sbrk).
+  DEFAULT_TRIM_THRESHOLD
+  DEFAULT_TOP_PAD
+  DEFAULT_MMAP_THRESHOLD
+  DEFAULT_MMAP_MAX
+     Default values of tunable parameters (described in detail below)
+     controlling interaction with host system routines (sbrk, mmap, etc).
+     These values may also be changed dynamically via mallopt(). The
+     preset defaults are those that give best performance for typical
+     programs/systems.
+  USE_DL_PREFIX             (default: undefined)
+     Prefix all public routines with the string 'dl'.  Useful to
+     quickly avoid procedure declaration conflicts and linker symbol
+     conflicts with existing memory allocation routines.

+    M_TRIM_THRESHOLD is the maximum amount of unused top-most memory
+      to keep before releasing via malloc_trim in free().
+
+      Automatic trimming is mainly useful in long-lived programs.
+      Because trimming via sbrk can be slow on some systems, and can
+      sometimes be wasteful (in cases where programs immediately
+      afterward allocate more large chunks) the value should be high
+      enough so that your overall system performance would improve by
+      releasing.
+
+      The trim threshold and the mmap control parameters (see below)
+      can be traded off with one another. Trimming and mmapping are
+      two different ways of releasing unused memory back to the
+      system. Between these two, it is often possible to keep
+      system-level demands of a long-lived program down to a bare
+      minimum. For example, in one test suite of sessions measuring
+      the XF86 X server on Linux, using a trim threshold of 128K and a
+      mmap threshold of 192K led to near-minimal long term resource
+      consumption.
+
+      If you are using this malloc in a long-lived program, it should
+      pay to experiment with these values.  As a rough guide, you
+      might set to a value close to the average size of a process
+      (program) running on your system.  Releasing this much memory
+      would allow such a process to run in memory.  Generally, it's
+      worth it to tune for trimming rather tham memory mapping when a
+      program undergoes phases where several large chunks are
+      allocated and released in ways that can reuse each other's
+      storage, perhaps mixed with phases where there are no such
+      chunks at all.  And in well-behaved long-lived programs,
+      controlling release of large blocks via trimming versus mapping
+      is usually faster.
+
+      However, in most programs, these parameters serve mainly as
+      protection against the system-level effects of carrying around
+      massive amounts of unneeded memory. Since frequent calls to
+      sbrk, mmap, and munmap otherwise degrade performance, the default
+      parameters are set to relatively high values that serve only as
+      safeguards.
+
+      The default trim value is high enough to cause trimming only in
+      fairly extreme (by current memory consumption standards) cases.
+      It must be greater than page size to have any useful effect.  To
+      disable trimming completely, you can set to (unsigned long)(-1);

+    M_TOP_PAD is the amount of extra `padding' space to allocate or
+      retain whenever sbrk is called. It is used in two ways internally:
+
+      * When sbrk is called to extend the top of the arena to satisfy
+        a new malloc request, this much padding is added to the sbrk
+        request.
+
+      * When malloc_trim is called automatically from free(),
+        it is used as the `pad' argument.
+
+      In both cases, the actual amount of padding is rounded
+      so that the end of the arena is always a system page boundary.
+
+      The main reason for using padding is to avoid calling sbrk so
+      often. Having even a small pad greatly reduces the likelihood
+      that nearly every malloc request during program start-up (or
+      after trimming) will invoke sbrk, which needlessly wastes
+      time.
+
+      Automatic rounding-up to page-size units is normally sufficient
+      to avoid measurable overhead, so the default is 0.  However, in
+      systems where sbrk is relatively slow, it can pay to increase

+      be allocated using already-existing space will be serviced via mmap.
+      (If enough normal freed space already exists it is used instead.)
+
+      Using mmap segregates relatively large chunks of memory so that
+      they can be individually obtained and released from the host
+      system. A request serviced through mmap is never reused by any
+      other request (at least not directly; the system may just so
+      happen to remap successive requests to the same locations).
+
+      Segregating space in this way has the benefit that mmapped space
+      can ALWAYS be individually released back to the system, which
+      helps keep the system level memory demands of a long-lived
+      program low. Mapped memory can never become `locked' between
+      other chunks, as can happen with normally allocated chunks, which
+      menas that even trimming via malloc_trim would not release them.
+
+      However, it has the disadvantages that:
+
+         1. The space cannot be reclaimed, consolidated, and then
+            used to service later requests, as happens with normal chunks.
+         2. It can lead to more wastage because of mmap page alignment
+            requirements
+         3. It causes malloc performance to be more dependent on host
+            system memory management support routines which may vary in
+            implementation quality and may impose arbitrary
+            limitations. Generally, servicing a request via normal
+            malloc steps is faster than going through a system's mmap.
+
+      All together, these considerations should lead you to use mmap
+      only for relatively large requests.

+
+	Example for "~/.kermrc" Kermit init file for use with U-Boot
+
+	by Wolfgang Denk, 24 Jun 2001
+
+flash_param:
+
+        "kermit" script to automatically initialize the environment
+        variables on your target. This is most useful during
+        development when your environment variables are stored in an
+        embedded flash sector which is erased whenever you install a
+        new U-Boot image.
+

+
+send_cmd:
+
+	send_cmd U_BOOT_COMMAND
+
+        "kermit" script to send a U-Boot command and print the
+        results. When used from a shell with history (like the bash)
+        this indirectly adds kind of history to U-Boot ;-)

+
+        "kermit" script to automatically download a file to the
+        target using the "loadb" command (kermit binary protocol)
