d1c1ba85c7 ppc4xx: acadia: Add fdt support and fix section overlap problem
This patch adds fdt (flattened device tree) support to the AMCC
Acadia eval board. This increases the image size and it doesn't
fit anymore into 256kByte. Since we didn't want to remove features
from the configuration, we decided to increase the U-Boot image size
(add one flash sector).

Also changed the default environment definition to make it
independent of such changes.

The cross compiler is responsible for providing the correct libraries
and the logic to find the linking libraries.

64cd594e62 ppc4xx: Fix acadia_nand build problem
Don't include testdram() on NAND-booting target acadia_nand. This saves
a few bytes and makes the target build clean again.

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.

df8a24cdd3 [ppc4xx] Fix problem with NAND booting on AMCC Acadia
The latest changes showed a problem with the location of the NAND-SPL
image in the OCM and the init-data area (incl. cache). This patch
fixes this problem.

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

5d4a179013 ppc4xx: Update AMCC Acadia support for board revision 1.1
This patch updates the Acadia (405EZ) support for the new 1.1 board
revision. It also adds support for NAND FLASH via the 4xx NDFC.

Please note that the jumper J7 must be in position 2-3 for this
NAND support. Position 1-2 is for NAND booting only. NAND booting
support will follow later.

This patch adds support for the new AMCC Acadia eval board.

Please note that this Acadia/405EZ support is still in a beta stage.
Still lot's of cleanup needed but we need a preliminary release now.
