2014-04-14ARM: shmobile: Check r8a7791 MD21 at SMP bootMagnus Damm
On r8a7791 the hardware boot mode bit MD21 indicates if hardware debug mode is enabled or not. In case hardware debug mode is enabled print a warning and refrain from booting secondary CPU cores. Without this patch Koelsch with SW8-4 set to OFF will hang at SMP boot.

Tie in the APMU SMP code on r8a7791. When used together with the secondary CPU device node and smp_ops in the board specific code then this will allow use of the two Cortex-A15 cores in the r8a7791 SoC.
