Hi Fabian, It was ported to older intel architectures by Nicola Corna here : https://review.coreboot.org/#/c/21107/ I don't know what would need to be done to port it to work with amd, but in theory, all it needs is for the chipset to support SPI operations. If it can read and write to the spi flash for the purposes of the mrc.cache, then it should be easy to make it work. The real work to port it to other architectures was pretty much only to make sure the spi controller doesn't use global variables so it could be included in the bootblock and romstage.
Good luck. Youness. On Fri, Sep 15, 2017 at 12:40 PM, Fabian <coreb...@bufa.info> wrote: > Hi everyone, > > I try to get coreboot run on my H8SCM.
