Changes for v3:
- Rebase on master
- Fix checkpatch.pl Warnings
- Add IMX6_BMODE_UART macro for uart bootmode
- Remove value assignment in enum, since all enum list is order

Changes for v3:
- Update IMX6_BMODE_* shift macros with real number instead of bitops
- %s/IMX6_BMODE_SERIAL/IMX6_BMODE_SERIAL_ROM
- Assign enums with numbers so-that it can easy to see same in RM
- Update board MAINTAINERS file with imx6ul-isiot-emmc.dts file

Changes for v2:
- Rebase on master
- Add Is.IoT eMMC boot patches
- Add few mmc env patches on board

Applied to u-boot-imx, thanks !

The dts files fail to build:

I think that's because there is '/dts-v1/;' in the imx6ul-isiot.dtsi file and in imx6ul-isiot-*.dts files.
