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.
