commit 364609066b3ad1be8c5827405d6d3813c72a65a6 Author: Sebastian Andrzej Siewior bigeasy@linutronix.de Date: Fri Oct 26 19:01:45 2012 +0200
northbridge/sch: read the size of main memory from the proper register
I don't know if the size main memory supposed to be in PCI(0,0) reg 0x9c but it is not written there. The size of memory is written in src/northbridge/intel/sch/raminit.c to SCH port(2, 8, 4) (look for "Setting up TOM").
