24 This option enables support for systems using Cortex processor based
25 ARM core and logic (FPGA) tiles on the Versatile Express motherboard,
28 - CoreTile Express A5x2 (V2P-CA5s)
29 - CoreTile Express A9x4 (V2P-CA9)
30 - CoreTile Express A15x2 (V2P-CA15)
31 - LogicTile Express 13MG (V2F-2XV6) with A5, A7, A9 or A15 SMMs
32 (Soft Macrocell Models)
33 - Versatile Express RTSMs (Models)
35 You must boot using a Flattened Device Tree in order to use these
36 platforms. The traditional (ATAGs) boot method is not usable on
37 these boards with this option.

47 Provides common dependencies for Versatile Express platforms
48 based on Cortex-A5 and Cortex-A9 processors. In order to
49 build a working kernel, you must also enable relevant core
50 tile support or Flattened Device Tree based support options.

65 bool "Versatile Express Serial Power Controller (SPC)"
68 The TC2 (A15x2 A7x3) versatile express core tile integrates a logic
69 block called Serial Power Controller (SPC) that provides the interface
70 between the dual cluster test-chip and the M3 microcontroller that
71 carries out power management.
73 config ARCH_VEXPRESS_TC2_PM
74 bool "Versatile Express TC2 power management"
77 select ARCH_VEXPRESS_SPC
79 Support for CPU and cluster power management on Versatile Express
80 with a TC2 (A15x2 A7x3) big.LITTLE core tile.
