[PATCH 2/4] ARM: imx: Add support for switching primary/secondary boot mode to bmode

[sbabic at denx.de]

> The i.MX6/i.MX7 is capable of booting a secondary "redundant" system
> image in case the primary one is corrupted. The user can force this
> boot mode as well by explicitly setting SRC GPR10 bit 30. This can be
> potentially useful when upgrading the bootloader itself. Expose this
> functionality to the user.
