From e49631afa074e2cb8ea5baddbbe8b9483a491e32 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Wed, 12 Nov 2014 11:57:33 +0100 Subject: [PATCH] arm: am33xx: Handle NAND+I2C boot-device the same way as NAND Re-map NAND&I2C boot-device to the "normal" NAND boot-device. Otherwise the SPL boot IF can't handle this device correctly. Somehow booting with Hynix 4GBit NAND H27U4G8 on Siemens Draco leads to this boot-device passed to SPL from the BootROM. With this change, Draco boots just fine into main U-Boot.
