Please take a look at the file "cpu/ppc4xx/sdram.c". This will show you, how 
the memory-size detection is done on the ppc405 systems (with onboard sdram) 
using the "get_ram_size" function. The code has to be modified for the 440 
ppc's, since they have a different SDRAM controller (DDR).

Best regards,
