Hello,
I'm soliciting comments of this patchset. The patchset adds a driver for the cache controller(specifically the PL310). This cache controller can be found on many ARMv7 SoCs. I don't think it's used on ARMv8 platforms.
This driver will retrieve the cache properties from the board DTS files and set the corresponding bits in cache controller.
I think we can do something similar without make this driver and placing the file in /arch/arm/cpu/armv7, but wanted to get feedback.
To-dos: - Add error checking - Add more cache properties
Thanks,
