This patchset comprises changes into i2c-designware-amdpsp.c module which aims to add support for new SoCs, while keep backward compatibility with Cezanne platforms. Beside new algorithm introduced for the PSP-x86 communication, it also switches from MSR/MMIO access to SMN (System Management Network) since only the latter is working on both old new revisions of SoCs.
