Updated microcode for coreboot BIOS developers

We, the coreboot BIOS developers, have not received any microcode updates from AMD

(aimed towards patching the spectre v2 vulnerability). AMD sent these updated microcode binaries to

many motherboard and BIOS development companies, but forgot to send these files to us at coreboot


Could you please provide a standalone download of your updated microcode binaries, to make it possible for us

to include them to our coreboot BIOS running on AMD platforms ? We will appreciate if you will share these

updated microcode binaries with us - maybe together with SHA-256 or SHA-512 hashes of these files or GnuPG

signatures to ensure the security of transaction


Best regards,

Mike Banon,

coreboot BIOS firmware engineer,


P.S. Although, ideally these new updated microcodes should be committed to kernel/git/firmware/linux-firmware.git repository -->
directory called "amd-ucode" .Currently it contains the following files: microcode_amd.bin ,microcode_amd.bin.asc ,

microcode_amd_fam15h.bin ,microcode_amd_fam15h.bin.asc , microcode_amd_fam16h.bin ,microcode_amd_fam16h.bin.asc .

They have been last updated at 2015/16 year, and we would like to see them updated again
