Just to mention, I tried to boot this Debian image with the current git source, 
and it gets further:

...
[   93.369315] NET: Registered protocol family 17
[   93.528550] registered taskstats version 1
[   93.679537] drivers/rtc/hctosys.c: unable to open rtc device (rtc0)
[   93.903757] su: Cannot register IRQ 0
[   94.452512] Kernel panic - not syncing: Attempted to kill init!
[   94.631524] Press Stop-A (L1-A) to return to the boot prom
