[PATCH] arm64: enable kernel command line concatenation

From: George G. Davis
Date: Thu Aug 11 2022 - 19:12:48 EST


From: "George G. Davis" <davis.george@xxxxxxxxxxx>

Enable CONFIG_CMDLINE to extend the boot loader supplied cmdline. This
can then be used in config fragments to set command line arguments
specific to testing of different kernel config options.
