612f8f074f arm: Add support for ARMv8 (AArch64 & AArch32)
Note: AArch64 and AArch32 interworking is not supported. If you use an AArch64
kernel you are restricted to AArch64 user-mode binaries. This will be addressed
in a later patch.

Note: Virtualization is only supported in AArch32 mode. This will also be fixed
in a later patch.

25c1933ffe ARM: Fix issue with with way MPIDR is read to include affinity levels.
The simple_bootloader checks for CPU0 in a manner incompatible with systems
actually using affinity levels -- just looking at MPIDR[7:0].  However, in
future we may wish to use real affinity levels and this method will be in danger
of matching several CPUs with affinity0 = 0.

Match affinity2 == affinity1 == affinity0 == 0 instead.
