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. Signed-off-by: Stefan Roese <sr@denx.de> Cc: Marek Vasut <marex@denx.de>
