[coreboot] Samsung 550 Chromebook own Coreboot

[John Lewis]

Hi all,

Just want to confirm where we are in terms of things working or not.

The new system-agent binary works and recognises all 4 GB of RAM as 
long as an additional pei data field is added to Stefan's patches in 
http://review.coreboot.org/#/c/3831/ as detailed by Kyösti in the 
comments.

The patches in http://review.coreboot.org/#/c/3830/ don't appear to do 
anything for mrc.cache (it's still zero size) and this (or perhaps 
something else) results in a time to SeaBIOS prompt of between 5 to 9 
seconds.

I added a 64 GB SSD this afternoon, which I have working, but something 
strange went on with geometry - if I tried to dd the partition itself 
back it would crap out at 2 GB (this was after dd'ing the backed up mbr 
onto the new drive). If I dd'ed the whole device it worked, but the 
partition wouldn't mount, and fdisk would report that the partition was 
too large for the device. Luckily, after reboot, it worked anyway. :)

Summary: if we could get rid of the 5 to 9 second delay, and just 
confirm the drive detection geometry is A1 I think we are there.

John.
