​I have requested FSP MR2 but yet to receive it.
But I checked the FSP file included in ​Apollo_Lake_CB_MR3 release and it
has the same cksum with the FSP MR3 I have.
And this Apollo_Lake_CB_MR3 pre-compiled coreboot image is bootable on my
CRB! :( Confusing...
Anyway, good to know that your FSP MR2 is working.
I think will just wait for the MR2 and check again.

BTW, I notice this in your config:-
  CONFIG_CPU_UCODE_BINARIES="blobs/microcode_patch_1.bin"
I didn't set this in my previous configuration.
Is this from FIT tool?
I noticed there are 2 files after decomposing with FIT tool, "uCode Patch
1.bin" & "uCode Patch 2.bin"
But you only need 1 file here?

Thank you.
