I meant the existing show_boot_progress() code.

I think it's just an implementation detail wether you use an enum or
#defines here.

Right.

Note that there is more code when it comes to seven segment and
character based LCD displays - please see doc/README.LED_display,
include/led-display.h, common/cmd_display.c and
drivers/misc/pdsp188x.c on one side, or the highly board specific
display code using the same framework in board/a4m072/a4m072.c on the
other side.


Best regards,

Wolfgang Denk
