Hi everyone,

This is a v2 of the patch series to add support for NXP's i.MX7
SabreSD board. It's most likely lacking some advanced features, but
basics such as SD card, Ethernet and, of course, booting Linux seem to
work OK.

The patchset is updated to use defenitions from Uwe's most recent
submission ("ARM: i.MX7: provide DDR register definitions") so this
series has that as a dependency.

Patch 1/9 contains a fix for a pretty serious screw-up on my part, so
I think it should be applied to master as well.

Also, note, that for a reason I haven't been able to track down yet,
compiling Barebox + this patchset without support for FEC will cause
upstream kernel (at least 4.12-rc1) to hang during boot while trying
to access FEC's register file. I suspect clock initialization issue,
but, as I said, I did not find that out conclusively.

Anyway, as usual, any feedback is wellcome.

Thanks,
Andrey Smirnov

Changes since [v1]:

 - Convert GPIO fix to use (val & mask) == mask idom for all bit
   fields

 - Add a patch simplifying code of gpio_request_gpio()

 - Move PHY_ID constant to a separate file

 - Make sure that all board init code is placed behing appropriated
   of_compatible guard

 - Reference the source of DCD data

 - Add minor changes (help text, adherence to alphabetical order, etc.)
