Based on the downstream patch series in the WAGO PFC firmware SDK [1].
Downstream has support for other boards too, which we leave out for now
because no devices are available for testing. The upstream device trees
have been used as-is except that uart0 was set to "okay" so barebox can
enable the console on startup.

+WAGO PFC200 Fieldbus Controllers (AM335x based)
+================================================
+
+These devices already run a version of Barebox out of the box,
+although the debug console is disabled in the factory settings.
+
+Currently supported devices:
+
+* WAGO PFC200v3 750-8214
+
+Initial Device Preparation
+--------------------------
+
+The factory firmware looks for an MLO on the eMMC first.
+If nothing bootable is found there, the ROM code searches for a loader on the
+SD card instead.
+This means we have to erase the internal MLO in order to boot from the SD card.
+
+#. If you haven't set up your device yet,
+ grab a current `firmware <https://github.com/WAGO/pfc-firmware/releases>`_,
+ write it to an SD card, and boot the device with it.
+ You also need a DHCP server to connect to the device over ethernet.
+
+#. Connect to the web interface and log in with admin privileges.
+ (The default user is ``admin``, password ``wago``).
+
+#. Make sure that SSH is enabled and root login is allowed in
+ *Ports and Services* → *SSH*.
+
+#. Connect to the device over SSH, using user ``root`` and password ``wago``.
+
+#. The eMMC boot partition is */dev/mmcblk1p1*, which contains boot loaders
+ for several PFC variants (probably as a backup?),
+ but only the file named ``mlo`` is loaded by the AM335x ROM loader.
+
+ .. code-block:: console
+
+ root@PFC200V3-433502:~ mount /dev/mmcblk1p1 /mnt
+

+ -rwxr-xr-x 1 root root 91200 Sep 19 03:53 mlo.pfc200v3
+
+ .. note::
+
+ The following step makes your device unbootable without an SD card.
+ If something goes wrong, and the device can no longer boot,
+ write one of the firmware images referenced above to the SD card,
+ and go through the setup process again.
+ If you want to make the recovery process easier, make a copy of the
+ partition (e.g. using sftp or writing it onto a spare SD card.)
+
+ Remove the file ``mlo`` so the ROM loader tries to boot from the SD card.
+ You can always replace it later with one of the backup copies.
+
+Now Barebox can be booted from the SD card.
+
+Building Barebox
+----------------
+
+All necessary settings are part of *omap_defconfig* and *am335x_mlo_defconfig*.
+Build both configs to get an MLO in ``images/barebox-am33xx-pfc-750-821x-mlo.img``
+and a second-stage Barebox image in ``images/barebox-am33xx-pfc-750-821x.img``.
+
+Booting from the SD card
+------------------------
+
+With these two images, prepare an SD card according to :ref:`am335x_starting_barebox`,
+and boot the device with it.
+
+A serial console is available on the debug port on the front of the machine
+(behind the cover next to the "RUN/STOP/RESET" switch and the SD card port).
+Use a WAGO serial cable (750-920 or 750-923) to connect to the serial console
+with 115200 Baud, 8N1.
+
+Writing Barebox to the Internal eMMC
+------------------------------------
+
+The SD card is available in Barebox as */dev/mmc0*, and the eMMC is */dev/mmc1*.
+You can copy ``mlo`` and ``barebox.bin`` from */mnt/mmc0.0/* to */mnt/mmc1.0/*,
+and then boot from the eMMC without the SD card.

Better differenciate it from the new MACH_WAGO_PFC_AM335X above it, and
fix indentation to be consistent with the rest of the file.

You register a MAC for eth0 once here...

And then here again. Please decide, or implement a fallback if one

Why only register an update handler only when we boot from MMC? This

This is done unconditionally. Why isn't this enabled in the device tree
already?
