Good work. Few minor problems:

Why not do alignment here? You could align for both dcache and icache,
this simplifies asm part and makes it a bit more robust.

Should be declared as const.

We have a macro for returns_twice.

Feels like it shouldn't be defined:
#undef GRUB_HAVE_UNALIGNED_ACCESS
Not defining those does no harm unless there is some weird unaligned device.

I'l need to merge those into install_c. Will you be available to test it?
