Some update on that.

( I still did not test with CONFIG_BLK_DEV_INITRD diabled )

I don't have myself an AMD system but someone tested the same config
but with AMD firmware and this works as expected.

[    0.545036] microcode: microcode updated early to new patch_level=0x010000c8

....

So it seems just the Intel part of the code does not work.
