The PHYTEC-phyCORE AT91M55800A is like a EB55, but only other FLASH,
so you only have to change the FLASH and the RAM-address (did you manage to 
get the CS8900A work).

I've only copied the EB55 directory and change the FLASH-Entries and 
RAM-address.
There is no need to change the sourcefile of the AMD-Flash.
