From 4520a2f28eade14b97618b37148ac615e78783df Mon Sep 17 00:00:00 2001 From: Priyanka Jain Date: Thu, 28 Nov 2013 10:12:16 +0530 Subject: [PATCH] powerpc: mmc: Add corenet devices support in esdhc spl Existing eSDHC SPL framework assumes booting from sd-image with boot_format header which contains final u-boot Image offset and size. No such header is present in case of corenet devices like T1040 as corenet deivces use PBI-RCW based intialization. So, for corenet deives, SPL bootloader use values provided at compilation time. These values can be defined in board specific config file.
