[U-Boot] [PATCH] OMAP3: Enable SPL on omap3_logic

Sat Jan 30 03:12:34 CET 2016
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.
