Yes, we already build a unified kernel for boards with the same phys
offset.  But with the current code each platform has a private static
Resource and platform device for the flash.  Since this data is not
tagged as __initdata it just takes up space after initialization.  If
a working runtime PHYS_OFFSET patch is ever worked out this static
data will increase for each ep93xx platform added.

Maybe "unified" is not the right term...
