From 91785f70b9b7ebfd1a2da4772a8268b36f58fa3d Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Tue, 27 Jan 2015 22:13:39 -0700 Subject: x86: mmc: Move common FSP functions into a common file Since these board functions seem to be the same for all boards which use FSP, move them into a common file. We can adjust this later if future FSPs need more flexibility. This creates a generic PCI MMC device.
