[coreboot] imb-a180 won't boot from single DIMM 0

Is there a straightforward way to get an IMB-A180 to boot with a single
DIMM in slot 0? It boots fine in slot 1. I've looked through the code
at length, and thought it configures the dimm, it fails in
coreboot/src/vendorcode/amd/agesa/Proc/Mem/Main/KB/mmflowKB.c
//----------------------------------------------------
// If there is no dimm on the system, do fatal exit
//----------------------------------------------------
if (NBPtr[BSP_DIE].RefPtr->SysLimit == 0) {
PutEventLog (AGESA_FATAL, MEM_ERROR_NO_DIMM_FOUND_ON_SYSTEM, 0, 0,
0, 0, &(MemMainPtr->MemPtr->StdHeader));
return AGESA_FATAL;
}
Even though it has detected and configured the dimm in slot 0.
Again, this does work with slot 1.
Many thanks,
