This shouldn't be necessary. See arch/arm/mach-omap/am33xx_scrm.c, here
the correct amount of memory should be registered.

am335x_barebox_entry() calculates the SDRAM size automatically for you.
Doing this has the advantage that you can configure your SDRAM as you
like without having to bother that all other locations where the SDRAM
size is needed are correct.
