From 93d9fc26cb7b4fcbb849e79d21d16b114e4501a9 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Thu, 3 Mar 2016 16:57:39 +0100 Subject: arm: socfpga: sr1500: Misc updates (SPI speed, env location) This patch makes the following changes to the SR1500 board port: - Update defconfig to support SPI NOR (use make savedefconfig). - Increase SPI speed to a maximum of 100MHz for faster system bootup. - Change environment location, so that its not between SPL and main U-Boot. This way the combined SPL / U-Boot image can be used for updates.
