From 1ac63e4094eee321266d5e5129077a3247d9439a Mon Sep 17 00:00:00 2001 From: Jerry Huang Date: Mon, 24 Jan 2011 17:09:54 +0000 Subject: powerpc/85xx: Enable eSDHC boot support on P2020 DS We implement our own mmc_get_env_addr since the environment variables are written to just after the u-boot image on SDCard, so we must read the MBR to get the start address and code length of the u-boot image, then calculate the address of the env.
