I'm running out of memory in linux on the smp86xx and attempting to
implement this solution. Did you ever get it to work? No luck for me
yet. I'm still a bit unclear why you must switch linux to run off DRAM
1 instead of leaving it on DRAM 0 and adding an additional call to
add_memory_region in prom_init for DRAM 1. But then again, I haven't
gotten that to work yet either :)
Any info/patches are greatly appreciated. Thanks!
Typically DRAM 1 must be accessed through the TLB as its address lays
outside of the 512MB window of KSEG[012].
The best way to make this memory available to Linux may still be up for
debate.
