Bring Microcode updates in CBFS .bin format

[Kinky Nekoboi]

Hello Everybody,

can somebody explain to me howto how the scripts in
3rdparty/blobs/cpu/intel/microcode/ alter the microcode.

Iwant to make the Microcode update provided by debian:
http://deb.debian.org/debian/pool/non-free/i/intel-microcode/intel-microcode...

I would like to alter the scripts an make a commit to master.

greetings

the current scripts assume that the updates are shipped in some
ASCII hex form. This changed long ago. Have a look at this patch
that updates the script and was used for the last round of updates:

https://review.coreboot.org/c/blobs/+/30065

Beside updating the URL, you'll probably have to adapt some path
to the directory structure in the tarball.

As Matt pointed out, you can get it more directly from Intel:

Thanks for looking into this.
