The documentation says
The main SPI flash can be accessed using flashrom, if the AmdSpiRomProtect modules have been deleted in the factory image previously.
So what does that mean? How can i do that? I would like to flash it internal
maybe Balazs could advise. However, to make sure you could easily unbrick your A88XM-E in the case of a bad coreboot build, I really recommend you to order a cheap USB CH341A programmer (preferably with a Green PCB) - and PLCC clip to easily remove a DIP8 flash chip from a motherboard's socket without bending the chip's legs. Then, you'll be able to easily install a new coreboot image by plugging a DIP8 flash chip into the programmer's socket and using the opensource flashrom tool.

The factory BIOS is write protected with that efi module. To have an unrestricted factory firmware, your options are: - dump the chip, remove the module and reflash the content - remove the module from the image you want to flash, and flash it with EZflash This module exists in the factory BIOS for the A88XM-E from the very beginning, and was introduced to F2A85-M in a later release. For more information please refer to: https://doc.coreboot.org/mainboard/asus/f2a85-m.html#internal-programming

I don't recognize the "AmdSpiRomProtect modules". My top guess, though, is it's referring to something that would program the RomProtect registers at D14F3x050, 54, etc. These are write-once and require a reset to unprotect the regions.
Thanks, Marshall
