ppc4xx: Add NAND booting support for AMCC Acadia (405EZ) eval board
This patch adds NAND booting support for the AMCC Acadia eval board.
Please make sure to configure jumper J7 to position 2-3 when booting
from NOR, and to position 1-2 when booting for NAND.
I also added a board command to configure the I2C bootstrap EEPROM
values. Right now only 267MHz is support for booting either via NOR
or NAND FLASH. Here the usage:
=> bootstrap 267 nor ;to configure the board for 267MHz NOR booting
=> bootstrap 267 nand ;to configure the board for 267MHz NNAND booting

This patch adds NAND booting support for the AMCC Bamboo eval board.
Since the NAND-SPL boot image is limited to 4kbytes, this version

supported, since the setup code for I2C DIMM autodetection and
configuration is too big for this NAND bootloader.

[PATCH] Run new sequoia boards with an EBC speed of 83MHz
Because the Sequoia board does not boot with an EBC faster than 66MHz,
the clock divider are changed after the initial boot process.
This allows for maximum clocking speeds to be achieved on newer boards.
Sequoia boards with 666.66 MHz processors require that the EBC divider
be set to 3 in order to start the initial boot process at a slower EBC
speed. After the initial boot process, the divider can be set back to 2,
which will cause the boards to run at 83.333MHz. This is backward
compatible with boards with 533.33 MHz processors, as these boards will
already be set with an EBC divider of 2.

[PATCH] Avoid assigning PCI resources from zero address
If a PCI IDE card happens to get a zero address assigned to it, the Linux IDE
core complains and IDE drivers fails to work. Also, assigning zero to a BAR
was illegal according to PCI 2.1 (the later revisions seem to have excluded the
sentence about "0" being considered an invalid address) -- so, use a reasonable
starting value of 0x1000 (that's what the most Linux archs are using).
Alternatively, one might have fixed the calls to pci_set_region() individually
(some code even seems to have taken care of this issue) but that would have
been a lot more work. :-)
