Subject[PATCH] arm64: enable kernel command line concatenation
Date
From: "George G. Davis" <davis.george@siemens.com>

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.
