This commit uses the new baseboard detection to make the descriptive output during boot ("This is a...") more meaningful.

uboot:cmd: refactor guf command

This commit removes all code which was previously used to detect the board, as this functionality was moved to board/keithkoep/common/baseboard*. Only code with the purpose to do the bootmode detection remains.

uboot:board: add generic platform and baseboard revision detection

This commit implements generic platform and baseboard revision detection for SBC and SOM systems. It currently supports PFID based baseboard detection.

  • baseboard.h: common interface to query baseboard type and revision. It defines the board types, detects whether PFIDs are used or some other system and forwards the calls to the proper implementation.
  • baseboard_pfids.h: type and revision detection using PFIDs
  • baseboard_util.h: utility functions for reading GPIO values

Some additional functions were made available in kuk_boards.h to implement the changes.
