From 7684b8582c24537dbe079a7d40e1d7e57ca56939 Mon Sep 17 00:00:00 2001 From: Masami Hiramatsu Date: Sat, 11 Jan 2020 01:03:44 +0900 Subject: bootconfig: Load boot config from the tail of initrd Load the extended boot config data from the tail of initrd image. If there is an SKC data there, it has [(u32)size][(u32)checksum] header (in really, this is a footer) at the end of initrd. If the checksum (simple sum of bytes) is match, this starts parsing it from there.
