From 367b8112fe2ea5c39a7bb4d263dcdd9b612fae18 Mon Sep 17 00:00:00 2001 From: Chris Zankel Date: Thu, 6 Nov 2008 06:40:46 -0800 Subject: xtensa: move headers files to arch/xtensa/include Move all header files for xtensa to arch/xtensa/include and platform and variant header files to the appropriate arch/xtensa/platforms/ and arch/xtensa/variants/ directories. Moving the files gets also rid of all uses of symlinks in the Makefile. This has been completed already for the majority of the architectures and xtensa is one out of six missing.
