no need board are allow in board/omap3
please create your own vendor dirent or just put it in board/

please define it before including cmd_default so no-need to undef CMD_FLASH &
CMD_IMLS

why no this
#define MTDPARTS_DEFAULT "mtdparts=nand:" \
"512k(x-loader)," \
"1920k(u-boot)," \
"128k(u-boot-env)," \
"4m(kernel),-(fs)"

here you can reduce duplicate code
as example by somthink like this
"commonargs=" \
"setenv bootargs console=${console} " \
"vram=${vram} " \
"omapfb.mode=dvi:${dvimode} " \
"omapdss.def_disp=${defaultdisplay} " \
"mmcargs=" \
"run commonargs; " \
"setenv bootargs ${bootargs}" \
"root=/dev/mmcblk0p2\0" \
