[PATCH 5/8] CMDLINE: mips: convert to generic builtin command line
Daniel Walker
danielwa at cisco.com
Tue Mar 30 18:57:00 BST 2021
This updates the mips code to use the CONFIG_GENERIC_CMDLINE
option.
This deletes the option for MIPS_CMDLINE_BUILTIN_EXTEND
and replaces the functionality with generic code.
This includes a scripted mass convert of the config files to use
the new generic cmdline. There is a bit of a trim effect here.
It would seems that some of the config haven't been trimmed in
a while.
The script used is as follows,
if [[ -z "$1" || -z "$2" ]]; then
echo "Two arguments are needed."
exit 1
fi
mkdir $1
cp $2 $1/.config
sed -i 's/CONFIG_CMDLINE=/CONFIG_CMDLINE_BOOL=y\nCONFIG_CMDLINE_PREPEND=/g' $1/.config
make ARCH=$1 O=$1 olddefconfig
make ARCH=$1 O=$1 savedefconfig
cp $1/defconfig $2
rm -Rf $1

- 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
- pass arguments to the kernel. For these platforms, and for the cases
- when you want to add some extra options to the command line or ignore
- the default command line, you can supply 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.

- For more information, see the CMDLINE_BOOL and CMDLINE_OVERRIDE
- options.

- By setting this option to 'Y' you will have your kernel ignore

- Instead, the built-in command line will be used exclusively.
