Probably I didn't commit all the old code I used to have.
Anyway, the things we have to do in early_mtrr.c are:
1. enable SYSCFG_MSR_MtrrFixDramModEn
2. set fixed mtrrs for 0-0x9FFFF and 0xC0000-0xFFFFF
as WB and READ_MEM and WRITE_MEM
3. set fixed mtrrs for 0xA0000-0xBFFF to UC
4. disable SYSCFG_MSR_MtrrFixDramModEn
5. enable SYSCFG_MSR_MtrrFixDramEn
