So far, we limited semihosting support to 32-bit ARM, but it's also
usable on ARM64 and even RISC-V.
This series does the first step by making it compile for ARM64 and also
adds DEBUG_LL and console drivers.
Ahmad Fatoum (6):
ARM: lib32: semihosting: prepare for more general use
firmware: semihosting: add ARMv8-A semihosting support
firmware: semihosting: don't return error code from writec/write0
firmware: semihosting: translate return values in wrappers
ARM: semihosting: add DEBUG_LL implementation
serial: add semihosting console
