* Avoid flicker on the TRAB's VFD by synchronizing the enable with

  the HSYNC/VSYNC. Requires new CPLD code (Version 101 for Rev. 100
  boards, version 153 for Rev. 200 boards).

* Patch by Vladimir Gurevich, 12 Mar 2003:
  Fix relocation problem of statically initialized string pointers
  in common/cmd_pci.c

* Patch by Kai-Uwe Bl�m, 12 Mar 2003:
  Cleanup & bug fixes for JFFS2 code:
  - the memory mangement was broken. It caused havoc on malloc by
    writing beyond the block boundaries.
  - the length calculation for files was wrong, sometimes resulting
    in short file reads.
  - data copying now optionally takes fragment version numbers into
    account, to avoid copying from older data.
  See doc/README.JFFS2 for details.

+ * - overhaul of the memory management. Removed much of the "paper-bagging"
+ *   in that part of the code, fixed several bugs, now frees memory when
+ *   partition is changed.
+ *   It's still ugly :-(
+ * - fixed a bug in jffs2_1pass_read_inode where the file length calculation
+ *   was incorrect. Removed a bit of the paper-bagging as well.
+ * - removed double crc calculation for fragment headers in jffs2_private.h
+ *   for speedup.
+ * - scan_empty rewritten in a more "standard" manner (non-paperbag, that is).
+ * - spinning wheel now spins depending on how much memory has been scanned
+ * - lots of small changes all over the place to "improve" readability.
+ * - implemented fragment sorting to ensure that the newest data is copied
+ *   if there are multiple copies of fragments for a certain file offset.
+ *
+ * The fragment sorting feature must be enabled by CFG_JFFS2_SORT_FRAGMENTS.
+ * Sorting is done while adding fragments to the lists, which is more or less a
+ * bubble sort. This takes a lot of time, and is most probably not an issue if
+ * the boot filesystem is always mounted readonly.
+ *
+ * You should define it if the boot filesystem is mounted writable, and updates
+ * to the boot files are done by copying files to that filesystem.
+ *
+ *
+ * There's a big issue left: endianess is completely ignored in this code. Duh!
+ *
+ *
+ * You still should have paper bags at hand :-(. The code lacks more or less
+ * any comment, and is still arcane and difficult to read in places. As this
+ * is incompatible with any new code from the jffs2 maintainers anyway, it

+ *  IO port access primitives
+ *  -------------------------
+ *
+ * The ARM doesn't have special IO access instructions; all IO is memory
+ * mapped.  Note that these are defined to perform little endian accesses
+ * only.  Their primary purpose is to access PCI and ISA peripherals.
+ *
+ * Note that for a big endian machine, this implies that the following
+ * big endian mode connectivity is in place, as described by numerious
+ * ARM documents:
+ *
+ *    PCI:  D0-D7   D8-D15 D16-D23 D24-D31
+ *    ARM: D24-D31 D16-D23  D8-D15  D0-D7
+ *
+ * The machine specific io.h include defines __io to translate an "IO"
+ * address to a memory address.
  *
  * Note that we prevent GCC re-ordering or caching values in expressions
  * by introducing sequence points into the in*() definitions.  Note that
  * __raw_* do not guarantee this behaviour.
+ *
+ * The {in,out}[bwl] macros are for emulating x86-style PCI/ISA IO space.
