I have questin on using DIMM with 860
There are no probelems with DIMM-s on 8260, but on 860 there are no
specialized BankSelect lines.
But there are plenty of DIMM types

On 860 there are some choises:
 -there are a lot of jumpers (or 0-ohm reistors)
 -use only one type of DIMM(which is not acceptable)
 -use somechip selects,and there are MEMORY HOLES in them

Q: Is  there any simpleway to use non-linear addresedmemory in linux? If
so, how to enable this in kernel?


for example there is:
0x0000_0000 .. 0x001f.ffff memory
0x0010_0000 .. 0x002f.ffff NOTHING!!!
0x0020_0000 .. 0x003f.ffff memory
