The current process to generate a kernel .config file from a defconfig
is a bit cumbersome:
$ ptxdist extract kernel
$ cd platform-foo/build-target/linux-<version>
$ make ARCH=... CROSS_COMPILE=... foo_defconfig
$ cp .config ../../../configs/platform-foo/kernelconfig
All kernel and barebox rules and templates already support the
<package>_%config target since commit b0f9f2fe33ca9027a554 (2020-08-07,
"barebox, kernel: enable use of {allyes, allno, allmod, alldef,
rand}config"), so we only need to wire them into the command line
parser, and then we can easily get a defconfig like this:
$ ptxdist defconfig kernel # most ARCHs
$ ptxdist imx_v6_v7_defconfig kernel # e.g. with ARCH=arm
