Patch by Jon Loeliger, 16 Jul 2004:

- support larger DDR memories up to 2G on the PC8540/8560ADS and
  STXGP3 boards
- Made MPC8540/8560ADS be 33Mhz PCI by default.
- Removed moldy CONFIG_RAM_AS_FLASH, CFG_FLASH_PORT_WIDTH_16
  and CONFIG_L2_INIT_RAM options.
- Refactor Local Bus initialization out of SDRAM setup.
- Re-implement new version of LBC11/DDR11 errata workarounds.
- Moved board specific PCI init parts out of CPU directory.
- Added TLB entry for PCI-1 IO Memory
- Updated README.mpc85xxads

-1.1 First, make sure the board default setting is consistent with the document
+1.0 Nomenclature
+
+    For some reason, the HW designers describe the switch settings
+    in terms of 0 and 1, and then map that to physical switches where
+    the label "On" refers to logic 0 and "Off" (unlabeled) is logic 1.
+    Luckily, we're SW types and virtual settings are handled daily.
+
+    The switches for the Rev A board are numbered differently than
+    for the Pilot board.  Oh yeah.
+
+    Switch bits are numbered 1 through, like, 4 6 8 or 10, but the
+    bits may contribute to signals that are numbered based at 0,
+    and some of those signals may be high-bit-number-0 too.  Heed
+    well the names and labels and do not get confused.
+
+    "Off" == 1
+    "On"  == 0
+
+    SW18 is switch 18 as silk-screened onto the board.
+    SW4[8] is the bit labled 8 on Switch 4.
+    SW2[1:6] refers to bits labeled 1 through 6 in order on switch 2
+    SW3[7:1] refers to bits labeled 7 through 1 in order on switch 3
+
+1.1 For the MPC85xxADS Pilot Board
+

     shipped with your board. Then apply the following changes:

+    If you want to test PCI functionality with a 33Mhz PCI card, you will
     have to change the system clock from the default 66Mhz to 33Mhz by
     setting SW15[1]="OFF" and SW17[8]="OFF". After that you may also need
     double your platform clock(SW6) because the system clock is now only
     half of its original value. For example, if at 66MHz your system
     clock showed SW6[0:1] = 01, then at 33MHz SW6[0:1] it should be 10.
 
-1.3 SW6 is a very important switch, it decides your platform clock and CPU
-    clock based on the on-board system clock(default 66MHz). Check the
-    document along with your board for details.

+    rate of 825 +/- fuzz:
+
+	Clocks: CPU: 825 MHz, CCB: 330 MHz, DDR: 165 MHz, LBC:	82 MHz
+
+    For 33MHz PCI, the switch settings should be like this:

+	SW18[7:1] = 0100001 = M==33 =>	  33MHz
+	SW18[8]	  =	  1	    => PWD Divider == 16
+	SW16[1:2] =	 11	    => N == 16 as PWD==1
+
+    Use the magical formula:

+
+	SW7[1:4]  =    1010 = 10    => 10 x 33	 = 330	CCB Sysclk
+	SW7[5:6]  =	 01	    => 5:2 x 330 = 825	Core clock
+
+
+    For 66MHz PCI, the switch settings should be like this:
+
+	SW18[7:1] = 0100001 = M==33 =>	  33MHz
+	SW18[8]	  =	  0	    => PWD Divider == 1
