Philipp Tomsich e92e580350 rockchip: ARM64: puma-rk3399: get DRAM size from DMC init 
With the RK3399 DRAM controller (DMC) driver providing all the
infrastructure, retrieve the DRAM size from the DMC init in the
board-specific code (instead of hard-coding) for the RK3399-Q7 (Puma).

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

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
=================

	> tools/mkimage -n rk3399 -T rksd -d spl/u-boot-spl.bin spl.img
	> tools/mkimage -f board/theobroma/puma_rk3399/fit_spl_atf.its \
		-E rk3399_bl3x.itb

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

Copy the SPL to offset 32k and the FIT image containing the payloads
(U-Boot proper, ATF, M0 Firmware, devicetree) to offset 256k on a SD
card.

  > dd if=spl.img of=/dev/sdb seek=64
  > dd if=rk3399_bl3x.itb of=/dev/sdb seek=512

After powering up the board (with the inserted SD card), you should see
a U-Boot console on UART0 (115200n8).
