to commit id 7c3b60bb:
2023-10-13 firmware/2lib: Use SSE2 to speed-up Montgomery multiplication
This brings in 3 new commits:
7c3b60bb firmware/2lib: Use SSE2 to speed-up Montgomery multiplication
8bb2f369 firmware: 2load_kernel: Set data_key allow_hwcrypto flag
2b183b58 vboot_reference: open drive rdonly when getting details
6ee22049 sign_official_build: switch from dgst to pkeyutl
da69cf46 Makefile: Add support for make 4.3
Also update the implementations of the vb2ex_hwcrypto_modexp() callback
to match the API changes made in vboot.
