Thanks, the physical addresses turned out to be all I needed. I just added
the banks to the dram and dma range tables and threw them at the vm system
as free pages, and it seems to work; Board comes up with 64MB RAM reported
in dmesg, and my little test program that allocates 48MB RAM and fills it
with ones and zeroes (and then takes another round to verify the contents
reads back ok, when it's sure it's long gone from the cache) works fine.
Since the board runs without swap, the program's certain to have stepped
around most of physical RAM. :)
Now for the interesting project: trying to write a framebuffer (and
eventually "wscons" virtual console) driver for my TS7KV... 8-)
