Thanks, I've applied to the next branch, after doing a few tweaks, see
below.

It would have been nice to indicate the upstream status of those
patches, especially since all of them are in Linus tree and therefore
will be in Linux 4.13. I've added a "Upstream: ..." tag to each of
them, with a link to the upstream commit.

I'm sure you wanted to say i.MX7D Pico board here, so I've fixed that.

We're not creating a bootable SD card here, but flashing the internal
eMMC, so I've adjusted that as well.

We want our defconfigs to be minimal, so I've dropped those additional
packages.

Thanks a lot!

+Subject: [PATCH] ARM: dts: imx7d-pico: Add watchdog support
+
+imx7d-pico has the WDOG1_B pin connected to the PMIC, so add the
+wdog1 node and use the 'fsl,ext-reset-output' property to
+properly describe it.

+Subject: [PATCH] ARM: dts: imx7d-pico: Pass 'no-1-8-v' property to the eMMC
+
+Currently the following eMMC error is seen:
+
+mmc1: mmc_select_hs200 failed, error -74
+
+On imx7d-pico the eMMC VCCQ is fixed at 3.15V, so pass the 'no-1-8-v'
+property to properly describe that 1.8V operation is not possible.

+****************************
+Technexion i.MX7D Pico board
+****************************
+
+This file documents the Buildroot support for the Technexion i.MX7D Pico board.
+
+Build
+=====
+
+First, configure Buildroot for the i.MX6UL Pico board:
+
+  make imx7dpico_defconfig
+
+Build all components:
+
+  make
+
+You will find in output/images/ the following files:
+  - imx7d-pico.dtb
+  - rootfs.ext4
+  - rootfs.tar
+  - sdcard.img
+  - u-boot.imx
+  - zImage
+
+Create a bootable SD card
+=========================
+
+In the U-Boot prompt lauch:
+
+=> ums 0 mmc 0
+
+This will mount the eMMC content in the host PC as a mass storage device.
+
+To determine the device associated to the eMMC card have a look in the
+/proc/partitions file:
+
+  cat /proc/partitions
+
+Buildroot prepares a bootable "sdcard.img" image in the output/images/
+directory, ready to be dumped on the eMMC card. Launch the following
+command as root:
+
+  dd if=output/images/sdcard.img of=/dev/<your-sd-device>
+
+*** WARNING! This will destroy all the card content. Use with care! ***
+
+For details about the medium image layout, see the definition in
+board/freescale/common/imx/genimage.cfg.template.
+
+Boot the i.MX7D Pico board
+==========================
+
+To boot your newly created system:
+- put a micro USB cable into the Debug USB Port and connect using a terminal
+  emulator at 115200 bps, 8n1;
+- power on the board.
+
+Enjoy!
