From 49c7303f0e526d46f8d16c5556963faf47c59d35 Mon Sep 17 00:00:00 2001 From: Adam Ford Date: Fri, 29 Jan 2016 20:12:34 -0600 Subject: [PATCH] OMAP3: Enable SPL on omap3_logic Previously, Omap3_logic assumed X-loader was present. With this patch, we can finally replace X-loader with an MLO generated by U-Boot. This requires ECC to be setup to match the Linux Kernel and the PBIAS confgured for the SD card.
