[coreboot] Success! Fwd: IMB-A180E H coreboot won't boot (new)

[Mark C. Mason]

Wim, you nailed it.  With a single-rank SODIMM the ASROCK IMB_A180 
coreboot build succeeds.

Much obliged!

We will look into the memory controller code next, as our design will 
use double-rank SODIMMs.

Hello Mark,

Have you tried using a slower SODIMM yet? I have seen issues here myself that 
were caused by the faster especially dual rank SODIMMs.

The easy solution is to simply use a slower or single rank SODIMM. The real 
solution is to manipulate the AGESA code for correct initialization of the 
memory controller.

I'm new to coreboot, and I'm working to use it with an ASROCK IMB-A180, the H 
version with the LVDS port.

I've read previous posts regarding the "IMB-A180 won't boot" on this group, and 
tried the .config that was posted, but the result is the same.

The debugging output shows things progressing until agesawwrapper_amdinitmid is 
called, then the boot restarts, then stops cold at the same point:

           PCI: 00:18.4
           PCI: 00:18.5
        Done allocating resources.
        BS: BS_DEV_RESOURCES times (us): entry 0 run 1095130 exit 0
        POST: 0x74
        Enabling resources...

        Fam16 - domain_enable_resources: AmdInitMid.
        agesawrapper_amdinitmid
<garbage characters>     Tue Feb 4     16:46:38 PST

Any help with this would be greatly appreciated.  Full serial debug output and 
.config are attached below.
