If you have you Flash mapped to 0x0000 - 0x3FFFF then you can't use your 
Flash as a Boot Device since the "SCx200 Core Logic module positively 
decodes memory addresses 000F0000h-000FFFFFh (64 KB) and 
FFFC0000h-FFFFFFFFh (256 KB) at reset".

Why don't you just get the application note "AMD Geode™ SC1200/SC2200/
SC3200 Processors: External NAND Flash Memory Circuit" and the Geode 
data sheet from AMD? They explain how all this works.
