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>2017.08.x

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
