[U-Boot] OMAP3: EVM: Linker errors across tool chain versions

[Dirk Behme]

What's the status of the linker errors across tool chain versions seen 
by building the 'omap3_evm' board?

This was already discussed in the threads [1] and [2], but it seems to 
me that there was no acceptable fix, yet?

E.g. with CodeSourcery's tool chain 2009q1-203 I get

arm-none-linux-gnueabi-ld: section .bss [8003f5e0 -> 8007e33f] 
overlaps section .rel.dyn [8003f5e0 -> 80044e6f]
arm-none-linux-gnueabi-ld: section .dynsym [80044e70 -> 80044f0f] 
overlaps section .bss [8003f5e0 -> 8007e33f]
arm-none-linux-gnueabi-ld: u-boot: section .bss vma 0x8003f5e0 
overlaps previous sections

What we learned from [2] is that using [3] fixes the build (at least 
for me with the tool chain mentioned above). I.e. converting 
omap3_evm_version from u8 to int

-static u8 omap3_evm_version;
+static int omap3_evm_version;

makes the issue disappear.

But if I understood the discussion correctly, this is no acceptable 
fix and can be used only as debug help (?).

Any further hints?

Thanks

Dirk
