No, it is not intended. commands/mem.c only gets compiled when
CONFIG_CMD_MEMORY is set, but this file should only contain the
commands, not the driver itself.
Anyway, you should set CONFIG_CMD_MEMORY in your config because
otherwise you won't have the memory commands (md, mw, memset,...) which
you probably want to have.
