commit: https://git.buildroot.net/buildroot/commit/?id=c5255422538103afa1acba50c54f81bcf07d7a0d
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master
Add support for mx6sx udoo neo boards. For more information about these
boards, please check:
http://www.udoo.org/udoo-neo
The U-Boot and kernel dts patches will be removed when we bump U-Boot
to 2017.01 and kernel to 4.10 version as they have already been sent
upstream.

+Subject: ARM: dts: imx6sx: Add UDOO Neo support
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Add initial device trees for UDOO Neo Basic, Extended and Full boards:
+* Serial console is enabled, other serial ports are prepared.
+* I2C based PMIC is enabled.
+* Ethernet is enabled for Basic and Full.
+* SDHC is enabled, with the SDIO_PWR GPIO modeled as a regulator.
+* Both user LEDs are enabled, with the orange one reserved for the M4
+ and with the SD card as default trigger for the red LED.
+
+The decision on a board compatible string is deferred to later.

+Subject: [PATCH] mx6sx: Add initial support for UDOO Neo Board
+
+UDOO Neo Board is a development board from Seco that has three models:
+ - UDOO Neo Basic
+ - UDOO Neo Basic Kick Starter
+ - UDOO Neo Extended
+ - UDOO Neo Full
+
+All versions are based on the i.MX6 SoloX processor.
+
+For more details about the UDOO Neo board, please refer to:
+http://www.udoo.org/udoo-neo/
+
+This work is based on a previous commit of Francesco Montefoschi
+<francesco.monte at gmail.com>:
+https://github.com/fmntf/u-boot/commit/877b71184a5105e708024f232d36aed574961844
+
+Only tested on the UDOO Neo Full board.

+MX6X Udoo Neo board

+http://www.udoo.org/udoo-neo/
+
+To build a minimal support for these boards:
+
+ $ make mx6sx_udoo_neo_defconfig
+ $ make
+
+Buildroot prepares a bootable "sdcard.img" image in the output/images/
+directory, ready to be dumped on an SD card:
+
+dd if=output/images/sdcard.img of=/dev/<your-microsd-device>
+
+For details about the medium image layout, see the definition in
