Hi,

I am not crazy about this patch. You need to use cpy_physical_memory_rw()
in the hob and nvram code too, not just in the ipf.c code.

What about the flush_icache_range() call you removed - is it safe to
just discard that?

I was in the process of working through this myself, but I am not
quite finished. If you don't mind waiting a couple hours, I should
have something a fair bit simpler to solve the same problem.

Biggest issue is the flush_icache_range() one.

Cheers,
Jes
