There is only one bank of DRAM on the H3700. Our bootldr autodetects how much
dram there is by probing. I suggest you look at boot-sa1100.s and bootldr.c
in our bootldr source code to see how to do this and how to adjust the memory
timings for the different memory configurations. Similarly for flash.

Actually, pocketpctechs.com will add a second bank of dram for you. There is
code in our bootldr to probe and enable that, but bootldr.c does not currently
inform Linux about it. I only recently received one of these to test on, so I
have not finished the code.
