I have two banks of SDRAM, one is 64M at 0x20000000, another is 64M at 0x60000000. I tried to use both of them in Linux (2.6.38). I hope the kernel will print Memory: 128MB = 128MB total Memory: 126236KB available (xxx code, xxx data, 112K init, 0K highmem) So I tried passing 'mem=64M at 0x20000000 mem=64M at 0x60000000' to Kernel command line.
