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.
The best way to make this memory available to Linux may still be up for debate.
