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Currently there is an extra (and outdated) rockchip-optee.dtsi which can create an u-boot.itb which can also hold the OP-TEE binary.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).
