coreboot

I build coreboot today for the ASUS P8Z77-V LX2 and used the latest coreboot master code.

The 2 8GiB DIMMs are working fine at first boot. You can start computer, install from a live media the OS and so on. But at the second boot it failes boot forever and its bootooping. It does not make a change if i boot for a second until SeaBIOS output and then turn off the computer or use the computer for longer time. The second boot is always broken.
Workaround 1: Remove one of the two 8GiB DIMMs. Then the computer also starts fine after a reboot.
Workaround 2: Install two 4GiB DIMMs instead of two 8GiB DIMMs. Then the computer also starts fine after reboot.
Workaround 3: At every boot boot for a second with one DIMM. Turn off the computer, insert the second DIMM and start it again.

kmalkki told me to rebuid the image with DEBUG_RAM_SETUP=y

I then build a second image, with DEBUG_RAM_SETUP=y.
The logfile contains the first successfull boot (created with Workaround 3), the poweroff and the poweron with the bootloop. I have let it bootloop few times before turned off the PSU.
