+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
