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.
Provides common dependencies for Versatile Express platforms based on Cortex-A5 and Cortex-A9 processors. In order to build a working kernel, you must also enable relevant core tile support or Flattened Device Tree based support options.
Support for the Dual Cluster System Configuration Block (DCSCB). This is needed to provide CPU and cluster power management on RTSM implementing big.LITTLE.
The TC2 (A15x2 A7x3) versatile express core tile integrates a logic block called Serial Power Controller (SPC) that provides the interface between the dual cluster test-chip and the M3 microcontroller that carries out power management.
