From f87427f1a4303d6cab26f29641831b4d3dec8451 Mon Sep 17 00:00:00 2001 From: Raul E Rangel Date: Tue, 9 Feb 2021 10:54:57 -0700 Subject: [PATCH] soc/amd/stoneyridge: Add SPI registers This is a copy/paste of amdblocks/lpc.h. The registers are different for picasso and cezanne, so I'm moving them to soc.
