Question about multi-bank memory usage in ARM platform

Question about multi-bank memory usage in ARM platform

[os user]

Hi Russell and list,

I have a question about multi-bank memory usage in ARM platform (arm926).

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.

Hi,

	A minimum of respect will to put your name in the e-mail
	and hide the chip and other information will not convince people to
	help you.
