board/orangepi: add basic support for orangepi-zero board
This patch adds basic support for orangepi-zero board. Board support package includes the following components: - mainline kernel v4.11 - mainline u-boot v2017.03 - extra kernel config options: spidev, spi nor flash, wifi - dts patches to enable SPI NOR and spidev More details about this board are available here: - http://linux-sunxi.org/Orange_Pi_Zero Note that at the moment networking is not supported right out of the box. Ethernet submission to mainline kernel is a work in progress, see the latest dwmac-sun8i branches at https://github.com/montjoie/linux On-board SDIO WiFi chip XR819 is supported by off-the-tree wireless driver available at https://github.com/fifteenhex/xradio Changes from v1: * Send patch using proper subject * Update xr819 kernel dts patch: add compatible property [Peter: fix s/PC/Zero/ typo] Signed-off-by: Sergey Matyukevich <geomatsi@gmail.com> Signed-off-by: Peter Korsgaard <peter@korsgaard.com>

+Subject: [PATCH 1/3] ARM: dts: orange-pi-zero: specify XR819 WiFi chip
+ interrupts
+
+The orange-pi-zero board has Allwinner XR819 SDIO wifi chip. The board
+dts file provides a node enabling mmc1 controller. Together with an
+out-of-tree driver https://github.com/fifteenhex/xradio this node
+enables using the wifi chip.
+
+This commit specifies XR819 interrupt configuration for the driver.

+OrangePi Zero
+
+Intro
+=====
+
+This default configuration will allow you to start experimenting with the
+buildroot environment for the OrangePi Zero. With the current configuration
+it will bring-up the board, and allow access through the serial console.
+
+How to build it
+===============
+
+Configure Buildroot:
+
+ $ make orangepi_zero_defconfig
+
+Compile everything and build the SD card image:
+
+ $ make
+
+How to write the SD card
+========================
+
+Once the build process is finished you will have an image called "sdcard.img"
+in the output/images/ directory.
+
+Copy the bootable "sdcard.img" onto an SD card with "dd":
+
+ $ sudo dd if=output/images/sdcard.img of=/dev/sdX
