From 79d7cd31f9a3d3e75ae67f742aa5eb199cfa71cf Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Thu, 5 Aug 2010 13:25:56 +0100 Subject: [PATCH] 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.
