This small series addresses current problem with late loading of Intel
microcode in OpenWrt. Following the commit messages [1] and later
discussion, late loading off the microcode can be ineffective for some
processors [2] and for others disabled [3]. Also it is discouraged for
any processor starting from Haswell and Silvermont.
Therefore this series converts the Intel microcode bundle to an initial
ram disk which is loaded with grub, so kernel has access to it as early
as possible.

No, Your grub doesn't understand *if* command because it's old an doesn't have
"test" module enabled. It's left there because sysupgrade doesn't upgrade grub,
it updates only boot and root partitions. If You'll write the created image not by
sysupgrade but by dd'ing to boot medium, It'll start properly without interruptions.
BTW thank You for the report.

Press any key to continue...

Can I repair this somehow without writing the full image ? only by reversing
the commits ?
No, not at the moment. I'm trying to figure out best way to update grub on
sysupgrade, until then reverting the mentioned commits will bring back old
behavior, and no manual intervention on boot will be necessary.
shall we revert the series ?
Yes, but not the whole series only these commits:
546fced2a23557e95dd34246744c3aa6cad92fe6 x86: add intel microcode entries to
grub config
022ffb56b2491fd7d8051ac6e6c7622ecc313d8f intel-microcode: create early load
microcode image
a822283c7e56bb3b409712e0eb9af5a91aac247d x86: add amd microcode entries to grub
config
975019b3a755ec3b91864b60b45e5ee104075096 amd64-microcode: create early load
microcode image
The rest is okay, won't cause any regressions and will save the effort.
Thank You.
done ....
