This is useful for kernel debugging when your machine crashes very

config CMDLINE_BOOL
bool "Built-in kernel command line"

help
For most systems, it is firmware or second stage bootloader that
by default specifies the kernel command line options. However,
it might be necessary or advantageous to either override the
default kernel command line or add a few extra options to it.
For such cases, this option allows you to hardcode your own
command line options directly into the kernel. For that, you
should choose 'Y' here, and fill in the extra boot arguments
in CONFIG_CMDLINE.
The built-in options will be concatenated to the default command
line if CMDLINE_OVERRIDE is set to 'N'. Otherwise, the default
command line will be ignored and replaced by the built-in string.
Most MIPS systems will normally expect 'N' here and rely upon
the command line from the firmware or the second-stage bootloader.

On some platforms, there is currently no way for the boot loader to

some command-line options at build time by entering them here. In
other cases you can specify kernel args so that you don't have
to set them up in board prom initialization routines.
