The I2C bootstrap values that can be setup via the "bootstrap" command,
were setup incorrect regarding the generation of the internal sync PCI
clock. The values for PLB clock == 133MHz were slighly incorrect and the
values for PLB clock == 166MHz were totally incorrect. This could
lead to a hangup upon booting while PCI configuration scan.
This patch fixes this issue and configures valid PCI divisor values
for the sync PCI clock, with respect to the provided external async
PCI frequency.
Here the values of the formula in the chapter 14.2 "PCI clocking"
from the 440EPx users manual:
AsyncPCICLK - 1MHz <= SyncPCIClk <= (2 * AsyncPCIClk) - 1MHz
33MHz async PCI frequency:
PLB = 133:
=> 32 <= 44.3 <= 65 (div = 3)
PLB = 166:
=> 32 <= 55.3 <= 65 (div = 3)
66MHz async PCI frequency:
PLB = 133:
=> 65 <= 66.5 <= 132 (div = 2)
PLB = 166:
=> 65 <= 83 <= 132 (div = 2)

The BCSR status bit for the 66MHz PCI operation was correctly
addressed (MSB/LSB problem). Now the correct currently setup
PCI frequency is displayed upon bootup.
This patch also fixes this problem on Rainier & Yellowstone, since these
boards use the same souce code as Sequoia & Yosemite do.

The ATSTK1000-specific flash driver intializes bi_flashstart,
bi_flashsize and bi_flashoffset, but other flash drivers, like the CFI
driver, don't.
Initialize these in board_init_r instead so that things will still be
set up correctly when we switch to the CFI driver.

CFG_MEMTEST_START uses weird magic involving gd, which fails to
compile. Use hardcoded values instead (we actually know how much RAM
we have on board.)

CFG_FPGA_XILINX is a bit value used to test against the value in
CONFIG_FPGA. Testing for a value will always return TRUE. I don't
think that is the intention in this code.

/bin/bash and /bin/dash (which /bin/sh is linked to on ubuntu) handle embedded
nulls in a string differently. For example, the following statement:
echo "this is a string\0" > afile
Will produce the following with /bin/bash:
"this is a string\0"
But with /bin/dash, will produce:
"this is a string
Bug fixed by moving the embedded null out of the makefile and into the
config header. Also renamed the macro to avoid usage colision with the same
macro used by other board ports.

The MCC200 board config file includes version.h for some customer-
specific setting, which causes warnings with "make depend"; build
version.h before depend.
