This architecture is a bit strange. It has up to four SDRAM banks, but all have a quite limited size. The SDRAM size for the different boards currently is unknown as it's configurable with Kconfig. We use a SDRAM size based on the value of the only board we have in the defconfigs: edb9301. This likely breaks other ep93xx boards.
