Wolfgang Denk 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.

To make a system for gth that actually works ;-)
the variable TBASE needs to be set to 0,1 or 2
depending on location where image is supposed to
be started from.
E.g. make TBASE=1

0: Start from RAM, base 0

1: Start from flash_base + 0x10070

2: Start from flash_base + 0x30070

When using 1 or 2, the image is supposed to be launched
from miniboot that boots the first U-Boot image found in
flash.
