From c01c71bc16d2836c3ff81af54529dab0686bca00 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sat, 7 Feb 2015 10:47:29 -0700 Subject: [PATCH] arm: spl: Provide for a board-specific loader Some boards have a special way of loading U-Boot that does not fit with the existing SPL code. For example sunxi uses an 'FEL' mode where U-Boot is loaded over USB. Add a CONFIG option and boot mode for this.
