When I'm building for AM437x HS and running on the device I don't see
that output. It seems like there is something funny going on with
CONFIG_SPL_DISPLAY_PRINT. Even though this definition is activated in
ti_omap4_common.h and ti_omap5_common.h it is not seen by
preloader_console_init() in spl.c, hence the function that prints the
chip-type/rev specifics never gets invoked.
Madan,
can you please confirm that behavior on your end?
Thanks,
