This patch set introduces ARMv8 PSCI framework, all the PSCI functions are implemented a default dummy one, it is up to each platform to implement their own specific ones.
The first 1/6 patch is a prepare clean up for adding ARMv8 PSCI. Patches 2/6 to 5/6 introduce new ARMv8 framework and set it up. The last 6/6 adds a most simple implementation on NXP LS1043 platform, to verify this framework.
This patch set mainly introduces ARMv8 PSCI framework, for easier review and merge, further PSCI implementation on LS1043 is coming later.
Hongbo Zhang (6): ARMv8: LS1043A: change macro CONFIG_ARMV8_PSCI definition ARMv8: Add secure sections for PSCI text and data ARMv8: Add basic PSCI framework ARMv8: Setup PSCI memory and dt ARMv8: Enable SMC instruction ARMv8: LS1043A: Enable LS1043A default PSCI support
Conceptually this is good. I have some issues around order of the patches, and where the Kconfig entries end up. Looking over the series we introduce usage of some CONFIG symbols prior to declaring them in Kconfig. This is more of a hard no now as it will break bisecting when the test for no new CONFIG symbols is tripped. The other problem is that I think the symbols you're adding in board/freescale/ls1043ardb/Kconfig need to be in arch/arm/cpu/armv8/Kconfig and then use default ... if ... to give the right address for the layerscape boards.
