Hi May,
you might have already gotten past this, but I thought I'd comment.
The codebase you're working from is intel's proof of concept
implementation. I don't remember if they have the MRC cache enabled.
For Rangeley/Avoton platforms though, saving and restoring the MRC cache
required, not optional as it is on many other FSPs.
The MRC cache is for saving the state of the memory controller. Other
FSPs require that the MRC data get saved and restored for S3 resume and
for "Fast Boot". For Rangeley it's required that it get restored every
time. If the MRC cache isn't restored, the system gets reset an
additional time on boot. If the platform doesn't have the hardware for
a full power down sequence (blade systems are the example I saw), then
the system will hang on reset about 30% of the time.
If the code to save and restore the MRC cache isn't available in the
codebase you're using, I'd recommend switching to a codebase that does.

Hello Viktor,
I went thru your log file attached below, and I found a difference
between our coreboot.rom which used the same Rangeley platform (Mohon
Peak CRB).
would you please tell me how you generate this hightlighted mrc.cache
file, I didn't find any configuration in 'menuconfig' or Kconfig
files. My code base is '*RANGELEY_CB_POSTGOLD_001_20131218*' which was
downloaded from Intel website.
I've already googled 'mrc.cache' but hardly found much hits, what is
this file for? could you please also give some hints :)
Thanks
May

*Subject:* [coreboot] SeaBIOS, serial output, grub, sgabios does
not seem to load
Hello,
I've been trying to boot grub installed on the hard drive using
coreboot
and SeaBIOS as a payload. The motherboard I'm using is Intel Mohon
Peak.
Also, I do not use VGA for output, only serial port. So, I
included the
sgabios into my rom file. Here is its layout:
$ ./build/cbfstool build/coreboot.rom print
coreboot.rom: 8192 kB, bootblocksize 1024, romsize 8388608, offset
0x600000
alignment: 64 bytes, architecture: x86

fsp.bin 0x77ffc0 (unknown) 372736
(empty) 0x7db000 null 150424
The issue is, it looks like SeaBIOS does not load sgabios at all.
Here is the SeaBIOS output, debug level 7 (I also put it in the
attachment):

The last five lines is clearly grub output, only after this goes
nothing
and it seems to me that sgabios does not forward VGA output to the
serial port.
So, how do I fix that? Am I missing something?
