From: Peng Fan Date: Wed, 10 Jan 2018 05:20:31 +0000 (+0800) Subject: imx: refactor imx_get_mac_from_fuse X-Git-Tag: v2018.03-rc2~47^2~53 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=6ce8b10b873e2c9812e2a82ca534396b9ae4f08b;p=oweals%2Fu-boot.git imx: refactor imx_get_mac_from_fuse Move imx_get_mac_from_fuse to a new mac.c for i.MX6/7. Since fuse regs structure are different for i.MX6/7, use mac address offset in code and define a new local struture imx_mac_fuse. Also sort the config order.
