* cpukit/aarch64: Use correct context register setsKinsey Moore2021-10-011-0/+19
| | | | | | | Context validation for AArch64 was ported from the ARM implementation without a reinterpretation of the actual requirements. The spcontext01 test just happened to pass because the set of scratch registers in ARM is a subset of the scratch registers in AArch64.
* score: Add AArch64 portKinsey Moore2020-10-051-0/+100
This adds a CPU port for AArch64(ARMv8) with support for exceptions and interrupts.
