Hello Iru Cai,
I'd like you to do a code review. Please visit
https://review.coreboot.org/c/coreboot/+/46130
to review the following change.
Change subject: [WIP] mb/hp: Add HP ProBook 640 G1 ......................................................................
[WIP] mb/hp: Add HP ProBook 640 G1
Generate code from autoport. It boots to Arch Linux in a USB disk from SeaBIOS payload.
EC ACPI doesn't work yet.
This board doesn't have HP Sure Start enabled, so we can use all the flash regions, and relocate the EC firmware with CB:41393.

EC ACPI doesn't work yet.
This board doesn't have HP Sure Start enabled, so we can use all the flash regions, and relocate the EC firmware with CB:41393.
