Change Log ========================== 2020.8 Update OP-TEE message protocol OP-TEE message protocol is updated from version 1 to version 2 on platform RK312x/RK322x/RK3288/RK3399/RK3399Pro/RK3368/RK3328/RK3228H. This message protocol update involves some software component, including OP-TEE(trust.img), U-Boot, Kernel, binary&library in Android/Linux. The software component above **MUST** be consistent because OP-TEE message protocol v1 and v2 are not compatible, otherwise TEE related function will **NOT** work normally. One Very Important Change: MMU policy for share memory between REE and TEE +-------+-----------------+----------------+ | arch | before update | after update | +-------+-----------------+----------------+ | arm64 | dcache enabled | dcache enabled | +-------+-----------------+----------------+ | arm | dcache disabled | dcache enabled | +-------+-----------------+----------------+ Related commits are shown below: 1. rkbin c20711e rk3036: tee: update optee version to v2.00 cb7d8f9 rk322x: tee with ta: update optee version to v2.11 4f9488e rk3128x: tee with ta: update optee version to v2.11 6d6473c rk312x: tee with ta: update optee version to v2.01 c0b025b rk3288: tee with ta: update optee version to v2.01 664ccee rk3228h/rk3328: bl32: update version to 2.01 6334115 rk3368: bl32: update version to 2.01 ccf1bef rk3399pro: bl32: update version to 2.01 8c01e53 rk3399: bl32: update version to 2.01 2. uboot 7a349fdcbd lib: optee_client: add optee initialize flag 74eb602743 lib: optee_client: update to new optee msg for optee v1 platform 102dfafc4a rochchip: board: map op-tee memory as dcache enabled 396e3049bd rochchip: board: only map op-tee share memory as dcache enabled 3. kernel 1) 4.19 90928381ffa9 ARM: dts: rockchip: add firmware and optee node d752a21c0853 arm64: dts: rockchip: add firmware and optee node c31ab35ad86d ARM: rockchip_defconfig: enable CONFIG_TEE and CONFIG_OPTEE 4.
