Hi,
Generally, I like idea of keeping rk3328.dtsi in sync with the Linux kernel source.

With a new board from a recent Linux DT the U-boot rk3328.dtsi is in need for an update.
Please advise what to do with usb3 regulators, aliases and other stuff that has to change.
Also some of the U-boot board files could use some dtbs_check for bogus properties and restyling... ;)
rk3328 USB2 and USB3 only roughly tested.

Howto use:
Compile bl31.elf:
git clone --depth 1 https://github.com/ARM-software/arm-trusted-firmware.git cd arm-trusted-firmware make realclean make CROSS_COMPILE=aarch64-linux-gnu- PLAT=rk3328
export BL31=/<path-to>/arm-trusted-firmware/build/rk3328/release/bl31/bl31.elf cd ..
Compile U-boot:
git clone --depth 1 https://github.com/u-boot/u-boot.git uboot cd uboot make CROSS_COMPILE=aarch64-linux-gnu- a95x-z2-rk3318_defconfig all
===
Use U-boot to create a GPT on a SD card, because of partition GUID and sizes.
mmc dev 0 mmc info gpt write mmc 0 $partitions mmc part
===
Write to SD card:
export DISK=/dev/mmcblk0 sudo dd if=./idbloader.img of=${DISK} seek=64 sudo dd if=./u-boot.itb of=${DISK} seek=16384 sync
===
Format boot partition with fat16. Add /Image and /rk3318-a95x-z2.dtb Add extlinux dir with extlinux.conf
label kernel kernel /Image fdt /rk3318-a95x-z2.dtb append root=/dev/mmcblk0p5 rw console=tty0 console=ttyS2,1500000n8 earlycon=uart8250,mmio32,0xff130000,keep $
===
Use fastboot:
Hit any key to stop autoboot: usb start usb dev 1 fastboot usb 1 = sudo fastboot devices -l sudo fastboot erase loader1 sudo fastboot erase loader2 sudo fastboot flash loader1 idbloader.img sudo fastboot flash loader2 u-boot.itb = ctrl-c reset
