From: Scott Wood Date: Sat, 18 Aug 2012 00:46:29 +0000 (-0500) Subject: spl/mpc85xx: move udelay to cpu code X-Git-Tag: v2013.01-rc2~117^2~18 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=59629c2897eb84c4550cf95b49e0761fbd23cef0;p=oweals%2Fu-boot.git 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.
