I have attached a patch (against this branch) that contains build
system fixes and changes to the assembly files in order to permit the
same target-platform combination to build correctly on both ARMv6 and
ARMv7, with no special options required.
It does also revert the removal of uboot_get_real_bss_start, since
this causes GRUB to fail even reaching "Welcome to GRUB!" on my
Trimslice. It may not be the best solution, but it is in there for a
There are also some "collateral" changes in this patch, holding other
fixes I have in my launchpad branch. Sorry about those.
This _should_ make your out-of-tree patch unnecessary.
