Subject: i.MX7 support

Message-ID: <20170116105108.13617-1-s.hauer@pengutronix.de> (raw)

The following series adds i.MX7 support to barebox. The port
was done on the WaRP7 board. The board starts, eMMC, USB and serial work.
This board does not have ethernet or NAND, so supporting this is
left for a later exercise.

It will be some additional fun to support the 2nd CPU for i.MX7d as we'll
need PSCI support then. So far we are limited to a single core, but
the only currently supported board is single core anyway.

One issue remaining is that I am currently unable to reset the board
using the watchdog or the barebox reset command. Out of ideas, will
fix later.
