[coreboot] X201i RAM upgrade not working

[Mono]

Hallo all,

Is anyone successfuly running the x201 port with two RAM modules installed? I am using it (commit 8128a56c0ec7e147d4ad68e6ba55979e9ead25ae from Sep 18) for booting a x201i computer with only one RAM module (2GB). As soon as I insert a second RAM module (2GB) it does not boot anymore. The screen stays black, grub is not showing up. Both modules work when just one of them is installed. Do I need to change anything in the coreboot configuration for supporting two RAM modules?

any help is much appreciated!
