The way it was intended from my point of view was to only specify (in
CONFIG_CMDLINE) the parameters that the boot loader doesn't specify.
We use it to let the boot loader (which is generic and whose config is
rather tricky to change) specify startup reasons and other probed
information that the kernel can't probe itself, and let the kernel handle
the rest, such as specifying memory regions and console tty's.
Thanks for reviewing, both of you.
