SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com> 2018-05-06 21:58:06 +00:00			`# SPDX-License-Identifier: GPL-2.0+`
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.

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> 2021-09-02 09:56:16 +00:00			`obj-y += optee.o`
