[Tee-dev] Need help in understanding OP-TEE boot flow on ARMv7.

Hi OP-TEE experts,

I am working on to integrate OP-TEE secure OS with u-boot on ARMv7 and came across following question that I need to clarify:

- It seems that optee-os doesn't save u-boot context at its entry point during its initialization.

o Like registers r0-r12, sp etc.

- Is it the responsibility of boot-loader (u-boot in my case) to save its context, pass

control to optee-os and then retrieve context after optee-os returns control back to boot-loader?

If someone can help clarify this it would be very much appreciated.

Thanks and regards, Sumit
