Here's V2 of r8a73a4 SMP prototype support. This time support for both CA15 and CA7 is included.
It is worth noting that only prototype support for the actual SoC is included here. It is included as SMP support, but since CA7 cores perform differently compared to CA15 the system will not behave in a deterministic way unless either big.LITTLE MP patches are used to extend the scheduler or c-groups are used to separate CA15 and CA7.
All 8 cores boot up as expected but certainly needs more work.
