From: Ralf Baechle Date: Thu, 5 Aug 2010 12:25:56 +0000 (+0100) Subject: MIPS: PNX8550: Move code one directory level up. X-Git-Tag: v3.0~4142^2~98 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=79d7cd31f9a3d3e75ae67f742aa5eb199cfa71cf;p=platform%2Fkernel%2Flinux-amlogic.git MIPS: PNX8550: Move code one directory level up. It was sharing the nxp directory but no code with pnx833x and will fit better into the new platform makefile scheme, if moved. Also after the pnx833x code has been moved up, the pnx8550 Code was the last users of the nxp dir.
