RTEMS ARMv8 Query

[Xu Ray]

There are some BSPs for V7. But V8 is 64bit instruction and I do not know
how well it is compatible with 32Bit instruction.

I think you can start with toolchain for V8 and begin with the cpukit
folder porting regarding the context switch and ISR handling.
QEMU 32 bit emulation for AArch64 may help you with initial debugging and
toolchain testing.
