From c0872f26d7fc4b8a30679ebdc7002ae8c072a0fb Mon Sep 17 00:00:00 2001 From: "Ronald G. Minnich" Date: Wed, 10 Jul 2013 15:22:17 -0700 Subject: Pit: move parade writes to mainboard.c What gets written into the parade is highly mainboard-dependent. So the parade_writes array needs to be there. Change-Id: Ia382d9bf1929e67b7c14d7a09f5461b71866a16b Signed-off-by: Ronald G.
