Hi,
While working on the ARM support for GRUB I noticed that the EFI support
in OE-core is a mess. A lot of it is due to GRUB insisting on its
byzantine config/install/skynet system and the rest is due to the
EFI==x86 assumption.
To improve this I'd like to start with adding an 'efi' MACHINE_FEATURE,
which will:
* Mask non-EFI configs like grub-pc/grub-uboot
* allow PACKAGECONFIG instead of distro/arch/machine overrides in grub2
* Activate logic in image classes to create a GPT EFI System Partition
Further steps to address EFI support would be:
* integrate gummiboot into OE-core (meta-intel has an old version)
* deprecate grub-(not really)native
* create an efi bbclass that does the above ESP dance and knows how to
populate it further e.g. grub.cfg and bootloader-spec entries for gummiboot.
* postinst magic to update bootloader config on kernel upgrade
Opinions/Flames/ACPI rants?
