From 7dbe63bc950bbd12d021f72bf04104688cd324a9 Mon Sep 17 00:00:00 2001 From: Tom Rini Date: Wed, 5 Feb 2014 10:24:18 -0500 Subject: [PATCH] SPL: Add CONFIG_SUPPORT_EMMC_BOOT support to CONFIG_SPL_FRAMEWORK We use the switch CONFIG_SUPPORT_EMMC_BOOT today to enable some additional features of the eMMC boot partitions. Add support for being told that we have booted from one of these partitions to the spl framework and implement this on TI OMAP/related.
