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.

66b3f24d66 Make DECLARE_GLOBAL_DATA_PTR global for DaVinci
As discussed in [1], DECLARE_GLOBAL_DATA_PTR has to be global and not
function local.

c74b2108e3 [ARM] TI DaVinci support, hopefully final
Add support for the following DaVinci boards:
- DV_EVM
- SCHMOOGIE
- SONATA

Changes:

- Split into separate board directories
- Removed changes to MTD_DEBUG (or whatever it's called)
- New CONFIG_CMD party line followed
- Some cosmetic fixes, cleanup etc.
- Patches against the latest U-Boot tree as of now.
- Fixed CONFIG_CMD_NET in net files.
- Fixed CONFIG_CMD_EEPROM for schmoogie.
- Made sure it compiles and works (forceenv() link problem) on SCHMOOGIE and
   DV_EVM. Can't check if it works on SONATA, don't have a board any more,
   but it at least compiles.

Here is an excerpt from session log on SCHMOOGIE...
