Philipp Tomsich 224d261a16 rockchip: board: lion-rk3368: reduce env-size default to 8KiB 
We want to have the same configuration defaults for the RK3368-uQ7
as for the RK3399-Q7: this change reduces the default env-size to
8KiB to ensure that it does not overlap the boot-payload on SD/MMC
configurations.

Here is the step-by-step to boot to U-Boot on RK3368-uQ7

Get the Source and build ATF
============================

  > git clone git://git.theobroma-systems.com/arm-trusted-firmware.git
  > cd arm-trusted-firmware
  > make CROSS_COMPILE=aarch64-linux-gnu- PLAT=rk3368 bl31
  > cp build/rk3368/release/bl31.bin ../u-boot/bl31-rk3368.bin

Configure U-Boot
================

  > cd ../u-boot
  > make lion-rk3368_defconfig

Build the TPL/SPL stage
=======================

  > make CROSS_COMPILE=aarch64-unknown-elf- ARCH=arm
  > tools/mkimage -n rk3368 -T rksd -d tpl/u-boot-tpl.bin spl-3368.img
  > cat spl/u-boot-spl-dtb.bin >> spl-3368.img

Build the full U-Boot and a FIT image including the ATF
=======================================================

  > make CROSS_COMPILE=aarch64-unknown-elf- ARCH=arm u-boot.itb

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

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

SD-Card
-------

  > dd if=spl-3368.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/rk3368_loader_v2.00.256.bin
  > ./rkdeveloptool wl 64 ../spl.img
  > ./rkdeveloptool wl 512 ../u-boot.itb


If everything went according to plan, you should see the following
output on UART0:
