Select this option if you want to run EFI applications (like
grub2)
I understand that with the progress we make on EFI implementation and other
parts of U-Boot the U-Boot image size is growing too big for direct loading
by the primary boot loader.
The OPENRD boards have abundant memory, e.g. openrd_ultimate_defconfig
refers to a board with 512 MB RAM.
So I think completely disabling EFI is not the solution.
Instead building an SPL should be enabled for this architecture when the
image is becoming too big for direct load.
I am copying in the KIRKWOOD maintainers go get their view.
I'm defn open to alternatives.. I don't know too much about what the
limit was on these boards, other than we were close to it before, and
the additional uefi proto's add <4k to the image size, which was
enough to push it over the limit. Since this was effecting only a few
boards, I went with this.. if it is only a temporary fix that can be
removed soon, or if someone can do something better with a separate
SPL build in the near term, that would be great.
I personally have not used any Kirkwood based platforms in the last few
years (and don't have access to one). And I don't see activities here
from mother developers either. As adding SPL support is not trivial,
frankly I don't see that this will be done anytime soon if at all.
Perhaps the image size can be reduced by removing other features or
interfaces from the OPENRD platform instead (CMD_MII, JFFS2, ...)?
Thanks,
Stefan
