[PATCH v2 1/3] Documentation: i.MX: Increase :maxdepth: for board documentation

[Andrey Smirnov]

A number of board documentation file have subsections. Increase
:maxdepth: so we'd get proper TOC and numbering.

[PATCH v2 3/3] ARM: i.MX: Add support for ZII i.MX8MQ based devices

[Andrey Smirnov]

Add support for the following ZII i.MX8MQ based boards:

   - ZII i.MX8MQ RMB3
   - ZII i.MX8MQ Zest

Most of the basic peripherals are supported by this patch. More
advanced features such as PCIe, display support, etc, are planned to
be added later.

+ZII i.MX8MQ Based Boards
+========================
+
+Building Barebox
+----------------
+
+To build Barebox of ZII i.MX8MQ based board do the following:
+
+.. code-block:: sh
+
+  make ARCH=arm CROSS_COMPILE=<AArch64 toolchain prefix> mrproper
+  make ARCH=arm CROSS_COMPILE=<AArch64 toolchain prefix> zii_v8_defconfig
+  make ARCH=arm CROSS_COMPILE=<AArch64 toolchain prefix>
+
+Uploading Barebox via JTAG
+--------------------------
+
+Barebox can be bootstrapped via JTAG using OpenOCD (latest master) as
+follows:
+
+.. code-block:: sh
+
+        cd barebox
+        openocd -f Documentation/boards/imx/zii-imx8mq-dev/openocd.cfg --command "init; ddr_init; start_barebox"
