From 26935d1ecc3e92803de985473b1a124982a9e226 Mon Sep 17 00:00:00 2001 From: Felix Held Date: Tue, 8 Dec 2020 00:40:04 +0100 Subject: soc/amd: factor out legacy I/O and cf9 decode enable functions Replace sb prefix with fch prefix, since those are all FCHs and no south bridges any more. Verstage on PSP uses the I/O access mechanism instead of the MMIO one, so keep a separate function for that, but also move it to the common mmio_util file to have them all in one place.
