Semihosting is a mechanism that enables code running on a target to communicate and use the Input/Output facilities on a host computer that is running a debugger. This patchset adds support for semihosting in u-boot for RISCV64 targets.
CHANGES since v2: - Move the arch/arm/Kconfig common *SEMIHOSTING* config options from arch/arm/Kconfig to lib/Kconfig. - Improve the *SEMIHOSTING_FALLBACK config options in lib/Kconfig to depend on RISCV or ARM64. - Remove the arch/riscv/include/asm/semhosting.h file. - Improve the arch/riscv/lib/semihosting.c by removing the jump statement and moving the .align 4 to before the 2 .option directives.
