Hello,
I am adding a splash screen to the PocketBeagle and I noticed something odd while compiling U-Boot. In u-boot/board/ti/am335x/board.h there exists a group of pin muxing functions. Take enable_i2c0_pin_mux() for example. That function is used before the board type is read from eeprom. I see it in am335x/board.c in do_board_detect(). But If I try calling that function from board_late_init(), I get a compiler error (undefined reference to enable_i2c0_pin_mux). Why is this?
