46f373838e nand_spl: Update nand_spl to support 2k page size NAND devices
This patch adds support for booting from 2k page sized NAND device
(e.g. Micron 29F2G08AAC).

Tested on AMCC Canyonlands.

71665ebf88 ppc4xx: Add Canyonlands NAND booting support
460EX doesn't support a fixed bootstrap option to boot from 512 byte page
NAND devices. The only bootstrap option for NAND booting is option F for
2k page devices. So to boot from a 512 bype page device, the I2C bootstrap
EEPROM needs to be programmed accordingly.

This patch adds basic NAND booting support for the AMCC Canyonlands aval
board and also adds support to the "bootstrap" command, to enable NAND
booting I2C setting.

Tested with 512 byte page NAND device (32MByte) on Canyonlands.

64134f0112 Fix linker scripts: add NOLOAD atribute to .bss/.sbss sections
With recent toolchain versions, some boards would not build because
or errors like this one (here for ocotea board when building with
ELDK 4.2 beta):
ppc_4xx-ld: section .bootpg [fffff000 -> fffff23b] overlaps section .bss [fffee900 -> fffff8ab]

For many boards, the .bss section is big enough that it wraps around
at the end of the address space (0xFFFFFFFF), so the problem will not
be visible unless you use a 64 bit tool chain for development. On
some boards however, changes to the code size (due to different
optimizations) we bail out with section overlaps like above.

The fix is to add the NOLOAD attribute to the .bss and .sbss
sections, telling the linker that .bss does not consume any space in
the image.

9f798766aa ppc4xx: Fixed offset of refresh rate type for Bamboo on-board DDR SDRAM
This patch also adds a note to the fixed DDR setup for Bamboo NAND booting:

Note:
As found out by Eugene O'Brien <eugene.obrien@advantechamt.com>, the fixed
DDR setup has problems (U-Boot crashes randomly upon TFTP), when the DIMM
modules are still plugged in. So it is recommended to remove the DIMM
modules while using the NAND booting code with the fixed SDRAM setup!

c440bfe6d6 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

cf959c7d66 ppc4xx: Add NAND booting support for AMCC Bamboo (440EP) eval board
This patch adds NAND booting support for the AMCC Bamboo eval board.
Since the NAND-SPL boot image is limited to 4kbytes, this version
only supports the onboard 64MBytes of DDR. The DIMM modules can't be
supported, since the setup code for I2C DIMM autodetection and
configuration is too big for this NAND bootloader.

for the 4k NAND boot image so define bus_frequency to 133MHz here
which is save for the refresh counter setup.

07b7b0037a [PATCH] Speed optimization of AMCC Sequoia/Rainier DDR2 setup
As provided by the AMCC applications team, this patch optimizes the
DDR2 setup for 166MHz bus speed. The values provided are also save
to use on a "normal" 133MHz PLB bus system. Only the refresh counter
setup has to be adjusted as done in this patch.

For this the NAND booting version had to include the "speed.c" file
from the cpu/ppc4xx directory. With this addition the NAND SPL image
will just fit into the 4kbytes of program space. gcc version 4.x as
provided with ELDK 4.x is needed to generate this optimized code.
