From 59629c2897eb84c4550cf95b49e0761fbd23cef0 Mon Sep 17 00:00:00 2001 From: Scott Wood Date: Fri, 17 Aug 2012 19:46:29 -0500 Subject: spl/mpc85xx: move udelay to cpu code It applies to non-Freescale 85xx boards as well as Freescale boards, so it doesn't belong in board/freescale. Plus, it needs to come out of nand_spl if it's to be used by the new SPL.
