2018-02-19arch-arm: Add aarch64 semihosting supportAndreas Sandberg
Add basic support for Arm Semihosting 2.0 simulation calls [1]. These calls let the guest system call a simulator or debugger to request OS-like support when running bare metal code. With the exception of SYS_SYSTEM, this implementation supports all of the Semihosting 2.0 specification in aarch64.
