I guess I need to test incrementally for the memory size. Right?
No, the code already does that. You just have to make sure that your memory mapping is correct (i. e. that the area [base, base+maxsize] is mapped correectly in your memory controller).
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).
