[ptxdist] [PATCH v2 4/6] ptxdist: implement 'defconfig' commands for kconfig packages

[Roland Hieber]

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

[ptxdist] [PATCH v2 6/6] ptxdist: add 'init' commands to create new configs

[Roland Hieber]

The goal here is to give users a way to create a working BSP or platform
from scratch by asking only a minimal set of relevant questions and
letting the user press Enter about 15 times, instead of asking every
question in the whole platform and ptxconfig menu, which would require
pressing Enter about 428 times.

For that, we create two separate Kconfig menus, rules/Kconfig-init for
the ptxconfig, and platforms/Kconfig-init for the platformconfig, which
include only the relevant .in files from the full menus. Still, some
options from these .in files can be set to reasonable defaults for new
BSPs or platforms, which is done with two new defconfig files instead of
further outsourcing the relevant config options into single .in files.

With the 'init' subcommand, PTXdist first creates a standard directory
structure under configs/ if necessary, then creates a minimal config
file from the respective defconfig, and finally calls kconfig on the
respective Kconfig-init menu, asking the user for the remaining config
options. A silenced oldconfig run on the full menu file then takes care
to set all other config options to their defaults.

Re: [ptxdist] [PATCH v2 4/6] ptxdist: implement 'defconfig' commands for kconfig packages

What about the following?

	$ ptxdist extract kernel
	$ cp platform-foo/build-target/linux-<version>/arch/arm/configs/
bar_defconfig configs/platform-foo/kernelconfig
	$ ptxdist oldconfig kernel

This looks somehow like a weird syntax, but I have no idea for a better one. 
:-/

What about U-Boot?  Currently there's PTXCONF_U_BOOT_CONFIGSYSTEM_LEGACY and 
you can just use a defconfig name in there.

(That was actually not supposed to target defconfig in particular, but the pre 
kconfig U-Boot config mechanism, but it also works for recent U-Boot 
defconfigs.)

Hmm, I agree that this looks weird. And having a wildcard for a ptxdist
command is not something that I want. Maybe:

ptxdist defconfig kernel imx_v6_v7
