Sunxi (pine64-lts) SPL load BL32

You can use "sunxi-fel" tool(which is part of sunxi-tool[0]) to load
Secure OS on pine64.

Also, you have to use specific SPL binary[1] to make it work.Besides
that you need USB Type A Male to Type A male cable(connected
from host to upper USB socket on Pine64 machine)

So, you can try following from host machine(after building sunxi-tool package)

# /sunxi-fel -v -p spl sunxi-a64-spl32-ddr3.bin write 0x44000 bl31.bin
write 0x40000000 tee-pager_v2.bin write 0x4a000000 u-boot.bin write
0x42080000 Image write 0x43080000 sun50i-a64-pine64-plus.dtb reset64
0x44000

Hi Andre,

Right now, we club different binaries together using FIT image(if I am
right ?), is it a good idea to club Secure OS image as well
with in FIT for A64 based platform ?
