I'd like you to reexamine a change. Please visit
https://review.coreboot.org/c/coreboot/+/47006
to look at the new patch set (#12).
Change subject: mb/ocp/deltalake: Override console log level and UART IO port for SMM ......................................................................
mb/ocp/deltalake: Override console log level and UART IO port for SMM
Add VPD variable 'smm_log_level' that can be read and passed to SMM module. By default it's 0 therefore it disables most of the SMM log.
Override mainboard_set_smm_info() that reads VPD variables for SMM log level and UART IO port, and it's set to smm_board_info with bit encoding: bits[5:4]: uart io select, bits[3:0]: console log level.
Tested=On OCP Delta Lake, SMM log level can be changed via VPD variable.
