From 9e20560221807ca4b8c540311168fe3f0d48022d Mon Sep 17 00:00:00 2001 From: Tim Harvey Date: Thu, 14 May 2015 11:48:04 -0700 Subject: env_nand: use nand_spl_load_image for readenv if SPL The readenv() implementation of env_nand uses the mtd layer which is unnecessary overhead in SPL when we already have a nand_spl_load_image() function that doesn't need it. Using this instead eliminates the need to provide a mtd_read for SPL env as well as reduces code (4KB savings in IMX6 SPL).
