Thanks, very helpful.
I'm currently tracking down a bug in which linux/arch/arm/kernel/smp.c
scu_get_core_count() returns the value of the raw_readl of scu_base
+ SCU_CONFIG (0xfee00004) as the value of smpboot[0]. It seems to be
bypassing the a9mpcore.c code entirely. I'm not sure what's happening
there.
