Hi Fabio,
in this way you have two different U-Boot binaries only to manage the
two displays, and automatically some "dead code" is added to U-Boot
because CONFIG_SEIKO_WVGA is not defined.
What about to use a u-boot environment to select the display ? Could be
a better solution for you ? You can then have a single u-boot image
managing both displays. I did in this way for the mt_ventoux board
(board/mt_ventoux/mt_ventoux.c), maybe can this help ?
Regards,
Stefano
