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.

ee311214e0 Clean up the code according to codestyle:
(1) remove some C++ comments.
(2) remove trailing white space.
(3) remove trailing empty line.
(4) Indentation by table.
(5) remove {} in one line condition.
(6) add space before '(' in function call.
Remove some weird printf () output.
Add necessary comments.
Modified Makefile to support building in a separate directory.

99c09c4dec Change the TEXT_BASE from 0xFFF00000 to 0xFF000000.
Both work. 0xFF000000 seems more reasonable.
