On older platforms that boot an image with an appended DTB, or where
the boot loader has no support for updating chosen/bootargs, it is
common to rely on CMDLINE_FORCE.
While a fixed command line can make the kernel unbootable on other
platforms, it is not guaranteed to cause that. E.g. all Renesas boards
use the same chosen/bootargs in upstream DTS, which works fine if your
DHCP server hands out proper nfsroot parameters.

Always use the default kernel command string, even if the boot
loader passes other arguments to the kernel.
