Simon Glass 14ca9f7f5a dm: core: Rename ofnode_get_chosen_prop()
This function is actually intended to read a string rather than a
property. All of its current callers use it that way. Also there is no way
to return the length of the property from this function.

Rename it to better indicate its purpose, using ofnode_read as the prefix
since this matches most other functions.

Also add some tests which are missing for these functions.

Introduction
============

The RK3399-Q7 (Puma) is a system-on-module featuring the Rockchip
RK3399 in a Qseven-compatible form-factor.

RK3399-Q7 features:
	* CPU: ARMv8 64bit Big-Little architecture,
		* Big: dual-core Cortex-A72
		* Little: quad-core Cortex-A53
		* IRAM: 200KB
	* DRAM: 4GB-128MB dual-channel
	* eMMC: onboard eMMC
	* SD/MMC
	* GbE (onboard Micrel KSZ9031) Gigabit ethernet PHY
	* USB:
		* USB3.0 dual role port
		* 2x USB3.0 host, 1x USB2.0 host via onboard USB3.0 hub
	* Display: HDMI/eDP/MIPI
	* Camera: 2x CSI (one on the edge connector, one on the Q7 specified CSI ZIF)
	* NOR Flash: onboard SPI NOR
	* Companion Controller: onboard additional Cortex-M0 microcontroller
		* RTC
		* fan controller
		* CAN

Here is the step-by-step to boot to U-Boot on rk3399.

Get the Source and build ATF/Cortex-M0 binaries
===============================================

  > git clone git://git.theobroma-systems.com/arm-trusted-firmware.git
  > git clone git://git.theobroma-systems.com/rk3399-cortex-m0.git

Compile the ATF
===============

  > cd arm-trusted-firmware
  > make CROSS_COMPILE=aarch64-linux-gnu- PLAT=rk3399 bl31
  > cp build/rk3399/release/bl31.bin ../u-boot/bl31-rk3399.bin

Compile the M0 firmware
=======================

  > cd ../rk3399-cortex-m0
  > make CROSS_COMPILE=arm-cortex_m0-eabi-
  > cp rk3399m0.bin ../u-boot

Compile the U-Boot
==================

  > cd ../u-boot
  > make CROSS_COMPILE=aarch64-linux-gnu- puma-rk3399_defconfig all

Package the image
=================

Creating a SPL image for SD-Card/eMMC
  > tools/mkimage -n rk3399 -T rksd -d spl/u-boot-spl.bin spl_mmc.img
Creating a SPL image for SPI-NOR
  > tools/mkimage -n rk3399 -T rkspi -d spl/u-boot-spl.bin spl_nor.img
Create the FIT image containing U-Boot proper, ATF, M0 Firmware, devicetree
  > make CROSS_COMPILE=aarch64-linux-gnu-

Flash the image
===============

Copy the SPL to offset 32k for SD/eMMC, offset 0 for NOR-Flash and the FIT
image to offset 256k card.

SD-Card
-------

  > dd if=spl_mmc.img of=/dev/sdb seek=64
  > dd if=u-boot.itb of=/dev/sdb seek=512

eMMC
----

rkdeveloptool allows to flash the on-board eMMC via the USB OTG interface with
help of the Rockchip loader binary.

  > git clone https://github.com/rockchip-linux/rkdeveloptool
  > cd rkdeveloptool
  > autoreconf -i && ./configure && make
  > git clone https://github.com/rockchip-linux/rkbin.git
  > ./rkdeveloptool db rkbin/rk33/rk3399_loader_v1.08.106.bin
  > ./rkdeveloptool wl 64 ../spl_mmc.img
  > ./rkdeveloptool wl 512 ../u-boot.itb

NOR-Flash
---------

Writing the SPI NOR Flash requires a running U-Boot. For the sake of simplicity
we assume you have a SD-Card with a partition containing the required files
ready.

  > load mmc 1:1 ${kernel_addr_r} spl_nor.img
  > sf probe
  > sf erase 0 +$filesize
  > sf write $kernel_addr_r 0 ${filesize}
  > load mmc 1:1 ${kernel_addr_r} u-boot.itb
  > sf erase 0x40000 +$filesize
  > sf write $kernel_addr_r 0x40000 ${filesize}


Reboot the system and you should see a U-Boot console on UART0 (115200n8).
