lib: optee: remove the duplicate CONFIG_OPTEE The configuration CONFIG_OPTEE is defined 2 times: 1- in lib/optee/Kconfig for support of OPTEE images loaded by bootm command 2- in drivers/tee/optee/Kconfig for support of OP-TEE driver. It is abnormal to have the same CONFIG define for 2 purpose; and it is difficult to managed correctly their dependencies. Moreover CONFIG_SPL_OPTEE is defined in common/spl/Kconfig to manage OPTEE image load in SPL. This definition causes an issue with the macro CONFIG_IS_ENABLED(OPTEE) to test the availability of the OP-TEE driver. This patch cleans the configuration dependency with: - CONFIG_OPTEE_IMAGE (renamed) => support of OP-TEE image in U-Boot - CONFIG_SPL_OPTEE_IMAGE (renamed) => support of OP-TEE image in SPL - CONFIG_OPTEE (same) => support of OP-TEE driver in U-Boot - CONFIG_OPTEE_LIB (new) => support of OP-TEE library After this patch, the macro have the correct behavior: - CONFIG_IS_ENABLED(OPTEE_IMAGE) => Load of OP-TEE image is supported - CONFIG_IS_ENABLED(OPTEE) => OP-TEE driver is supported Signed-off-by: Patrick Delaunay <patrick.delaunay@foss.st.com>

optee: Add lib entries for sharing OPTEE code across ports This patch adds code to lib to enable sharing of useful OPTEE code between board-ports and architectures. The code on lib/optee/optee.c comes from the TI omap2 port. Eventually the OMAP2 code will be patched to include the shared code. The intention here is to add more useful OPTEE specific code as more functionality gets added.

an OPTEE image created with mkimage
optee: Add CONFIG_OPTEE_TZDRAM_SIZE OPTEE is currently linked to a specific area of memory called the TrustZone DRAM. This patch adds a CONFIG entry for the default size of TrustZone DRAM that a board-port can over-ride. The region that U-Boot sets aside for the OPTEE run-time should be verified before attempting to hand off to the OPTEE run-time. Each board-port should carefully ensure that the TZDRAM size specified in the OPTEE build and the TZDRAM size specified in U-Boot match-up. Further patches will use TZDRAM size with other defines and variables to carry out a degree of automated verification in U-Boot prior to trying to boot an OPTEE image.

help
Select this command to enable chain-loading of a Linux kernel
via an OPTEE firmware.
The bootflow is BootROM -> u-boot -> OPTEE -> Linux in this case.
