From 819833af39a91fa1c1e8252862bbda6f5a602f7b Mon Sep 17 00:00:00 2001 From: Peter Tyser Date: Mon, 12 Apr 2010 22:28:08 -0500 Subject: Move architecture-specific includes to arch/$ARCH/include/asm This helps to clean up the include/ directory so that it only contains non-architecture-specific headers and also matches Linux's directory layout which many U-Boot developers are already familiar with.
