Hi.
Now you have coreboot running.
coreboot searches for FSP, finds it and executes the first call into it.
FSP returns with an error and what you see is this (taken from
src/drivers/intel/fsp/cache_as_ram.inc):
/*
* Failures for postcode 0xBB - failed in the FSP:
*
* 0x00 - FSP_SUCCESS: Temp RAM was initialized successfully.
* 0x02 - FSP_INVALID_PARAMETER: Input parameters are invalid.
* 0x0E - FSP_NOT_FOUND: No valid microcode was found in the
microcode region.
* 0x03 - FSP_UNSUPPORTED: The FSP calling conditions were not met.
* 0x07 - FSP_DEVICE_ERROR: Temp RAM initialization failed
* 0x14 - FSP_ALREADY_STARTED: Temp RAM initialization has been invoked
*/
So what you actually see is error code 0x07 from FSP. This can mean that
your CPU is not supported by this FSP version.
If you use GOLD1 or GOLD2, then a D0 stepping is not supported and if
you have in advance a D0 stepping installed on your board,
than you have to use GOLD3 FSP release as it was already mentioned.
I had the same issue and it was due to missing D0-Support in GOLD1
release. So, I would suggest to try the right FSP-release from Intel.
Bye
