From ba09440131a707c4fabf2875b14521bcf2b86938 Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Fri, 22 Sep 2017 22:57:22 +0100 Subject: [PATCH] SPL: SPI: sunxi: add SPL FIT image support The sunxi-specific SPI load routine only knows how to load a legacy U-Boot image. Teach it how to handle FIT images as well, simply by providing the existing SPL FIT loader with the right loader routine to access the SPI NOR flash.
