Prepare for OP-TEE support in stm32mp1 #79

Closed etienne-lms closed 4 years ago

These files do not exist upstream, any plan to avoid diverging?

etienne-lms commented 4 years ago

stm32mp1 DTS/DTSI files were refactored between Linux kernel v5.5 and v5.6.

The PSCI part of this change was posted to the upstream [1] and should be applied on Linux kernel v5.8.

As for the OP-TEE node and related reserved memory, mainline Linux/stm32mp1 does not embed OP-TEE, hence this extra change in current P-R and likely be ported again when OP-TEE upgrades in kernel version.

Yeah, OK, those make sense to keep here of course.
