Hi,
My custom AT91 RM9200 board hangs on delay loop calibration. There it
seems to be stuck and the last message printed is:
[ 0.000000] Calibrating delay loop...
Doing a manual bisect I can get the board to boot again when I revert
the following commits from Linus master:
14070ade02cc378bc30dae383532768a94805988 - ARM: at91: fix new build errors
c4b68520dc0ec96153bc0d87bca5ffba508edfcf - ARM: at91: add AIC5 support
4c6971a6debb340d487cf6189f15a1332702330f - ARM: at91: remove mach/irqs.h
8fe82a5550a8e97b3f59c74f994b88ed6b3544a3 - ARM: at91: sparse irq support
3e135466745a62b1814edef74c7b4a25e6bda707 - ARM: at91: at91 based
machines specify their own irq handler at run time
There may be some unnecessary reverts here but there are multiple
build failures between the different commits (grrrrr) which makes it
pain to filter it out.
I suspect that right now all AT91 RM9200 machines are broken by these
IRQ changes on AT91.
regards
Joachim Eastwood

Thanks for this report. I have just sent a patch to correct the rm9200
breakage.
