From de93c3c119382cb888ca8a94b642dbcf8035525e Mon Sep 17 00:00:00 2001 From: Michal Simek Date: Fri, 28 Jan 2011 13:26:54 +0100 Subject: [PATCH] microblaze: Fix ASM optimized code for LE Microblaze little-endian doesn't support ASM optimized library functions(memcpy/memmove). Kconfig doens't contain any information about endian that's why it is necessary to check it in the source code. The code is used with barrel shifter is used.
