From 70fe2876352939194ccd9091379453a5ddb64ddb Mon Sep 17 00:00:00 2001 From: Kever Yang Date: Thu, 23 Aug 2018 17:17:59 +0800 Subject: spl: add support to booting with OP-TEE OP-TEE is an open source trusted OS, in armv7, its loading and running are like this: loading: - SPL load both OP-TEE and U-Boot running: - SPL run into OP-TEE in secure mode; - OP-TEE run into U-Boot in non-secure mode; To make code simple, it would be fine to use IH_OS_TEE for the os tyle in TPL(just like IH_OS_LINUX is using both in SPL and U-Boot). Here is the diagram for SPL loading OP-TEE, IH_OS_TEE:(make u-boot.itb for SPL) Non-Secure Secure BootROM | v SPL | v --------- OP-TEE | v U-Boot | V Linux For other two king of OP-TEE loading/booting, see commit message: 45b55712d4 image: Add IH_OS_TEE for TEE chain-load boot More detail: https://github.com/OP-TEE/optee_os and search for 'boot arguments' for detail entry parameter in: core/arch/arm/kernel/generic_entry_a32.S Signed-off-by: Kever Yang Cc: Bryan O'Donoghue Reviewed-by: Philipp Tomsich --- include/spl.h | 13 +++++++++++++ 1 file changed, 13 insertions(+) (limited to 'include/spl.h') diff --git a/include/spl.h b/include/spl.h index b42683c9e7..9a439f468b 100644 --- a/include/spl.h +++ b/include/spl.h @@ -288,6 +288,19 @@ int spl_mmc_load_image(struct spl_image_info *spl_image, */ void spl_invoke_atf(struct spl_image_info *spl_image); +/** + * spl_optee_entry - entry function for optee + * + * args defind in op-tee project + * https://github.com/OP-TEE/optee_os/ + * core/arch/arm/kernel/generic_entry_a32.S + * @arg0: pagestore + * @arg1: (ARMv7 standard bootarg #1) + * @arg2: device tree address, (ARMv7 standard bootarg #2) + * @arg3: non-secure entry address (ARMv7 bootarg #0) + */ +void spl_optee_entry(void *arg0, void *arg1, void *arg2, void *arg3); + /** * board_return_to_bootrom - allow for boards to continue with the boot ROM * -- cgit v1.2.3
