Subject: [PATCH] Add riscv64 architecture support
Add RISC-V 64-bit (riscv64) to the set of supported architectures.
RISC-V uses UEFI boot like aarch64, so no special bootloader partition
is needed.
Changes:
- discoverable_partition_specification: add riscv64 to this_arch_root()
- install: add riscv64 to ARCH_USES_EFI
- install/baseline: add riscv64 to partitioning arch checks
