4Subject: [PATCH 3/3] sd-boot: Support global kernel command line fragment
5
6Query file blob KBOOTPARAM from RMC. If it exists, we append
7it to the new linux boot entry's cmdline. A boot entry could
8be read from a .conf file on ESP, RMC database, or embedded
9linux image. content in KBOOTPARAM is effective in all of
10these cases.
