[U-Boot] [RFC PATCHv1 0/3] misc: pl310: add a dm cache driver

[Dinh Nguyen <dinguyen@kernel.org>]

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,
