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): 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.

Applied, after re-rworking it for the boards changed, renamed or added meanwhile.
Thanks. This fixes overlapping problems with bss as seen on Ocotea with ELDK 4.2. But unfortunately I still have other overlapping problems for example on Katmai with ELDK 4.2:
[stefan@ubuntu u-boot (master)]$ ./MAKEALL katmai Configuring for katmai board... 44x_spd_ddr2.c: In function 'initdram': 44x_spd_ddr2.c:392: warning: 'selected_cas' may be used uninitialized in this function ppc_4xx-ld: section .bootpg [fffff000 -> fffff377] overlaps section .data.rel.local [ffffeba8 -> fffff3f7] ppc_4xx-ld: u-boot: section .bootpg lma 0xfffff000 overlaps previous sections ppc_4xx-ld: u-boot: section .data.rel.ro lma 0xfffff3f8 overlaps previous sections ppc_4xx-ld: u-boot: section .u_boot_cmd lma 0xfffff408 overlaps previous sections make: *** [u-boot] Error 1
These error are not seen with ELDK 4.1 by the way. Any ideas what might be causing this and/or how to solve it?
Thanks.
Best regards, Stefan
