[coreboot] Link layer between "coreboot" - "seabios" - "coreinfo/nvramcui"

[Аладышев Константин]

I've found out that commit that broke down compatibility with my old
Coreboot was:

libpayload/libc/console: Flush input driver buffer on init
https://review.coreboot.org/#/c/coreboot/+/19345/

If I revert it with the newest Coreboot, payloads (coreinfo/nvramcui) will
work with my old Coreboot version.

Best regards,
Aladyshev Konstantin

Last lines of log from SeaBIOS:

Hello! 
I have a project for my motherboard with coreboot version that I fixed
couple years back (so it is pretty old), and now I want to update all
payloads to most modern ones. There is no problem with SeaBIOS, but coreinfo
and nvramcui don't work. When I try to jump to them from SeaBIOS, nothing
happens and screen turns black. So... what is the link layer between those
payloads and coreboot? Layer that I should also update for those new
payloads to work fine?

Don't forget, this it is not only video problem, there is no output from COM
also. So maybe it is connected to CBFS or payload format? What should I
check?
