I was going to try coreboot on an ASROCK FM2A88X Extreme4+ (
https://www.asrock.com/mb/AMD/FM2A88X%20Extreme4+/) with the configuration
of the supported ASUS A88XM-E (
https://doc.coreboot.org/mainboard/asus/a88xm-e.html) which has the same
chipset (A88X Bolton).
Welcome to coreboot. There is a very small chance, that using an image
from another board might damage the board due to GPIOs being
misconfigured, and a short-circuit is programmed.
The fact is that, at this moment, I only have a 16 MiB flash, while the
image is 8 MiB. As the chipset claims that it
“Supports a maximum SPI ROM size of 16MB” I think there should be no
problem, but I wonder how I have to burn the image. That led me to the
question of how the translation between CPU and flash addresses are done.
For supporting various ROM sizes, I guess the controller should somehow
know the size of the ROM, but I don't see anywhere where that could be
specified.
In `make menuconfig` in the section *Mainboard* adapt
ROM chip size (8192 KB (8 MB)) --->
to 16 MB. But it might be useful to also adapt the size for the CBFS
filesystem in ROM. (It’s automatically adapted if you delete `.config`
beforehand.)
In the past, taking the 8 MB file, and concatenating it twice to a 16 MB
image also worked.

Kind regards,
Paul
