Well, the reason you didn't see it is because I was apparently
smoking something that day. The _real_ filename (in the 2.0.1
I just downloaded from you local store) was mips-setup-simple.S.
This file doesn't exist in 2.0.2. I'll pull the latest and
test it. If it works for me in mips I'll bump the version in
BTW, the full path for that asm file is:
Unfortunately, I don't have much time (always the story, no?) as
I have a very important pre-release of what I'm doing with
kexec, so, forgive me if I don't get back to you with this for
a couple of days.
