This patch separates the PMU driver code from the low level CCI driver code and enables the PMU driver for ARM64. Introduces config options for both. ARM_CCI400_PORT_CTRL - controls the low level driver code for CCI400 ports. ARM_CCI400_PMU - controls the PMU driver code ARM_CCI400_COMMON - Common defintions for CCI400 This patch also changes: ARM_CCI - common code for probing the CCI devices. This can be used for adding support for newer CCI versions(e.g, CCI-500).

This option enables support for systems using Cortex processor based

ARM core and logic (FPGA) tiles on the Versatile Express motherboard,
|
|
for example:
|
|
|
|
- CoreTile Express A5x2 (V2P-CA5s)
|
|
- CoreTile Express A9x4 (V2P-CA9)
|
|
- CoreTile Express A15x2 (V2P-CA15)
|
|
- LogicTile Express 13MG (V2F-2XV6) with A5, A7, A9 or A15 SMMs
|
|
(Soft Macrocell Models)
|
|
- Versatile Express RTSMs (Models)
|

You must boot using a Flattened Device Tree in order to use these

platforms. The traditional (ATAGs) boot method is not usable on
|

these boards with this option.
