[RFC PATCH v1 0/6] add rk3318 A95X Z2 board

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
