I tested this patch for an am335x port, I soon post to mainline. With
this patch, it compiled again clean for me.

Just tried the "igep0030_nand_defconfig" ... yes, it fails also with
this patch:

without your patch:
arm-linux-gnueabi-ld.bfd: region `.sram' overflowed by 1176 bytes

with it:
arm-linux-gnueabi-ld.bfd: region `.sram' overflowed by 272 bytes

So, your patch saves some bytes, but this fix seems valid for me, so I
acked it ... But it seems, there are more issues with this board ...

Ah, Tom already posted another fix, see:

bye,
Heiko
