Commit Message

Daniel Walker April 16, 2021, 4:09 a.m. UTC
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.

Of note, the pic32 has some strange handling of the current built
in command line. It was converted to use the static variant which
can't be updated after compilation. It should eventually be updated
to use to append and prepend symbols.

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

-	  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 default command line, you can supply some command-line options at
