This includes support for rk3188 from Heiko Stübner and and rk3328 from
Kever Yang.  Also included is SPL support for rk3399 and a fix for
rk3288 to get it booting again (spl_early_init()).

Introduction
============
RK3328 key features we might use in U-Boot:
* CPU: ARMv8 64bit quad-core Cortex-A53
* IRAM: 36KB
* DRAM: 4GB-16MB dual-channel
* eMMC: support eMMC 5.0/5.1, suport HS400, HS200, DDR50
* SD/MMC: support SD 3.0, MMC 4.51
* USB: USB2.0 EHCI host port *2
* Display: RGB/HDMI/DP/MIPI/EDP
evb key features:
* regulator: pwm regulator for CPU B/L
* PMIC: rk808
* debug console: UART2
In order to support Arm Trust Firmware(ATF), we need to use the
miniloader from rockchip which:
* do DRAM init
* load and verify ATF image
* load and verify U-Boot image
Here is the step-by-step to boot to U-Boot on rk3328.
Get the Source and prebuild binary
==================================
> mkdir ~/evb_rk3328
> cd ~/evb_rk3328
> git clone https://github.com/ARM-software/arm-trusted-firmware.git
> git clone https://github.com/rockchip-linux/rkbin
> git clone https://github.com/rockchip-linux/rkflashtool
Compile ATF
===============
> cd arm-trusted-firmware
> make realclean
> make CROSS_COMPILE=aarch64-linux-gnu- PLAT=rk3328 bl31
Compile U-Boot
==================
> cd ../u-boot
> make CROSS_COMPILE=aarch64-linux-gnu- evb-rk3328_defconfig all
Compile rkflashtool
=======================
> cd ../rkflashtool
> make
Package image for miniloader
================================
> cd ..
> cp arm-trusted-firmware/build/rk3328/release/bl31.bin rkbin/rk33
> ./rkbin/tools/trust_merger rkbin/tools/RK3328TRUST.ini
> ./rkbin/tools/loaderimage --pack --uboot u-boot/u-boot-dtb.bin uboot.img
> mkdir image
> mv trust.img ./image/
> mv uboot.img ./image/rk3328evb-uboot.bin
Flash image
===============
Power on(or reset with RESET KEY) with MASKROM KEY preesed, and then:
> ./rkflashtool/rkflashloader rk3328evb
You should be able to get U-Boot log message in console/UART2 now.

Rockchip Dynamic Memory Controller Driver
Required properties:
- compatible: "rockchip,rk3399-dmc", "syscon"
- rockchip,cru: this driver should access cru regs, so need get cru here
- rockchip,pmucru: this driver should access pmucru regs, so need get pmucru here
- rockchip,pmugrf: this driver should access pmugrf regs, so need get pmugrf here
- rockchip,pmusgrf: this driver should access pmusgrf regs, so need get pmusgrf here
- rockchip,cic: this driver should access cic regs, so need get cic here
- reg: dynamic ram protocol controller(PCTL) address, PHY Independent(PI) address, phy controller(PHYCTL) address and memory schedule(MSCH) address
- clock: must include clock specifiers corresponding to entries in the clock-names property.
Must contain
dmc_clk: for ddr working frequency
- rockchip,sdram-params: SDRAM parameters, including all the information by ddr driver:
Must contain
Genarate by vendor tool and adjust for U-Boot dtsi.
Example:
dmc: dmc {
u-boot,dm-pre-reloc;
compatible = "rockchip,rk3399-dmc";
devfreq-events = <&dfi>;
interrupts = <GIC_SPI 1 IRQ_TYPE_LEVEL_HIGH 0>;

@ -825,6 +825,10 @@ drivers marked with DM_FLAG_PRE_RELOC or the device tree
'u-boot,dm-pre-reloc' flag are initialised prior to relocation. This helps
to reduce the driver model overhead.
It is possible to limit this to specific relocation steps, by using
the more specialized 'u-boot,dm-spl' and 'u-boot,dm-tpl' flags
in the devicetree.
Then post relocation we throw that away and re-init driver model again.
For drivers which require some sort of continuity between pre- and
post-relocation devices, we can provide access to the pre-relocation
