[PATCH v1 0/5] rockchip: Support OP-TEE binaries in ARM FIT images

[Alex Bee]

This adds support for OP-TEE binaries to Rockchip's ARM FIT image 
generation by binman.

Currently there is an extra (and outdated) rockchip-optee.dtsi which can
create an u-boot.itb which can also hold the OP-TEE binary. It has to be
included manually in the respective SoC-specific device trees. But even if
that is done, it won't be merged in rockchip-u-boot.bin, which aims to be 
platform-consistent.
The bootable FIT image must therefore currently be created manually.

This will be done automatically with this patch-set and a single
u-boot-rockchip.bin file with an bootable FIT image containing all
binaries will be generated.

Additionally this series adds a configuration option which has to be
set if a vendor-provided OP-TEE binary is used. This is required as those
use a different calling convention. 
For RK3036, RK3128 and RK3288 SoCs this currently the only option to get an
TEE, as no upstream implementation exists for them.
Those binaries can be found at [1]

There are also some adaptions for RK322x in order to successfully use that
FIT image and some changes to the documenation.

This series has been tested on RK3229 (both vendor and upstream OP-TEE) and
RK3288 (vendor implementation only).
