Subject: question: is it feasible to execute a UEFI-BIOS using x86 instructions on non-x86 platforms?
To: devel@edk2.groups.io

RAID disc controller cards usually have a built-in configuration program in
their BIOS. Some cards added a UEFI-BIOS
<http://www.dawicontrol.com/manuals/dc-raid_en.pdf> but still only build
this for x86 platforms.

I wonder if it is feasible to execute this code on the growing number of
non-x86 platforms via emulation (qemu,..) during boot.
