From 1f9ad44546ea872fc6671602eb411377dd424c9e Mon Sep 17 00:00:00 2001 From: Alexey Brodkin Date: Tue, 3 Feb 2015 13:58:14 +0300 Subject: [PATCH] arc: add selection of endianess in Kconfig This change allows to keep board description clean and minimalistic. This is especially helpful if one board may house different CPUs with different features. It is applicable to both FPGA-based boards or those that have CPUs mounted on interchnagable daughter-boards.
