From 2c17e6d1d996a1b8b9325de15f253a13d5877dee Mon Sep 17 00:00:00 2001 From: pekon gupta Date: Mon, 18 Nov 2013 19:03:02 +0530 Subject: am335x: fix GPMC config for NAND and NOR SPL boot GPMC controller is common IP to interface with both NAND and NOR flash devices. Also, it supports max 8 chip-selects, which can be independently connected to any of the devices. But ROM code expects the boot-device to be connected to only chip-select[0]. Thus to resolve conflict between NOR and NAND boot. This patch: - combines NOR and NAND configs spread in board files to common gpmc_init() - configures GPMC based on boot-mode selected for SPL boot.
