[coreboot] Modifying FSP in Binary Configuration Tool (BCT)

In my experience with my Baytrail system I can tell you my system is "really" memory down because has soldered memory chips on the motherboard BUT has also a soldered SPD memory so, if keep "Enable Memory Down = Disabled" in BCT the system fetch memory timings from SPD so, no need to edit memory timings but other things like "DRAM Speed" and "DRAM Type" and other settings (not timings) needs to be edited.

but if still needed to edit timings extract them from SPD with "i2c-tools-perl".... I alredy sent you this information in previous emails and attachments so, look for this.....

Good luck,
