@@ -8,30 +8,20 @@ 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
 
+Note: the riscv64 branch in this_arch_root() (in
+crates/lib/src/discoverable_partition_specification.rs) was accepted
+upstream in bootc commit 47c3620 ("fix: add riscv64 to this_arch_root")
+and is already present in v1.15.2, so it is no longer carried here.
