[U-Boot] [PATCH] arm: mx6: specify SPL padding

[Stefan Agner <stefan@agner.ch>]

From: Stefan Agner <stefan.agner@toradex.com>

When building SPL with eMMC boot support, specify standard padding
for payload to match the load sector during boot. This allows to
use the u-boot-with-spl.imx build target to generate a direcly
flashable image which can be flashed using:

  dd if=u-boot-with-spl.imx of=/dev/mmcblk0 bs=512 skip=2
