From 74752baa738ee9dafe69d726910e26da56f6f722 Mon Sep 17 00:00:00 2001 From: Scott Wood Date: Thu, 6 Dec 2012 13:33:16 +0000 Subject: spl: Change PAD_TO to CONFIG_SPL_PAD_TO This was already used by some SPL targets, and allows the pad amount to be specified by board config headers rather than only in makefile fragments. Also supply a pad-to of zero if the variable is undefined. It works without this, but this avoids relying on undocumented behavior.
