So it looks like they have the normal mtrrs.
Yep, appears so.
I tried the following this morning:
option XIP_ROM_SIZE= 0x01000000 option XIP_ROM_BASE= 0xff000000
This caches the top 16M. The decompress time went from 13 seconds (!!) to less than a second. Guess we better make sure to cache the upper ROM.
cat /proc/cpuinfo for my my unit lists as "Via Samuel 2" at 551Mhz and 1101BogoMips, otherwise the same as the one I posted in this thread yesterday.
