This may cause problems with build bots, please remove that line

Any specific reason for HZ=300?

You shouldn't need the command line override, as both the console port
and the memory size can reliably be found in the DTB

Please also make sure that any hardware specific drivers are enabled in
multi_v7_defconfig along with your platform specific one, and check
that multi_v7_defconfig works as well as your own config.
