Thanks for taking a look!
This is a prerequisite to just logically separate KGDB FIQ code from the
entry code.
Or to put it the other way around: KGDB FIQ is just another user of the
FIQs, nothing quite special in it to put it alongside the entry code. :-)
But if Russell or other folks feel that having KGDB FIQ asm code in
entry-armv.S makes sense, I'd definitely do this.
Thanks,
Anton.
