[OE-core] [PATCH v5 0/6] #10073: generic EFI for wic

[Ed Bartosh]

Hi,

This patchset is an implementation of generic EFI approach for wic images.

Instead of introducing yet another wic plugin it uses existing APIs from
EFI_PROVIDER classes to populate ${WORKDIR}/bootfs directory with EFI artifacts
and bootloader configuration. This directory can be used by wic rootfs plugin
to put into boot partition of the image.

Example kickstart file and 2 test cases were added to wic test suite to better
illustrate the approach.

I personally like this approach much better than duplicating oe image creation
functionality in wic plugins. This way we can have the code in one place and
bootloaders can be configured the same way for oe and wic images.

Changes in v2:
 - added patch: fixed default value of GRUB_ROOT
 - fixed typo in commit message: timage_types_wic > image_types_wic

Changes in v3:
 - scheduled do_prepare_wic_build as earlier as possible

Changes in v4:
 - fixed build on platforms that don't support EFI
 - fixed non-gpl3 build
 - fixed build failure in systemd-boot code caused by rescheduled
   do_populate_bootfs to run earlier

Changes in v5:
 - yet another fix for scheduling of do_prepare_wic_build: explicitly
   added dependencies do_prepare_wic_build -> EFI_PROVIDER:do_deploy
   in efi provider classes

   NOTE: to make this working on meta-intel we'll need to add dependency
         do_prepare_wic_build -> "${MLPREFIX}rmc-db:do_deploy"
         I'll send patch for this as soon as this patchset is accepted.
