2918eb9d42 Remove shell variable UNDEF_SYM.
UNDEF_SYM is a shell variable in the main Makefile used to force the
linker to add all u-boot commands to the final image. It has no use here.

ec724f883e ppc4xx: Change Kilauea to use the common DDR2 init function
This patch changes the kilauea and kilauea_nand (for NAND booting)
board port to not use a board specific DDR2 init routine anymore. Now
the common code from cpu/ppc4xx is used.

Thanks to Grant Erickson for all his basic work on this 405EX early
bootup.

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.

3d6cb3b24a ppc4xx: Add AMCC Kilauea/Haleakala NAND booting support
This patch adds NAND booting support for the AMCC 405EX(r) eval boards.
Again, only one image supports both targets.
