+Subject: [PATCH 13/18] powerpc: Load firmware trusted keys/hashes into kernel
+ keyring
+
+The keys used to verify the Host OS kernel are managed by firmware as
+secure variables. This patch loads the verification keys into the
+.platform keyring and revocation hashes into .blacklist keyring. This
+enables verification and loading of the kernels signed by the boot
+time keys which are trusted by firmware.
