[PATCH] x86: coreboot: Show a coreboot logo if booted from coreboot

Wed Nov 29 18:52:08 CET 2023

U-Boot shows its own logo when starting up, if a display is active. Add
a coreboot logo too, for when U-Boot is booted from coreboot.

Note that the logo's license applies:
https://coreboot.org/Logo#coreboot_Logo_License
