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

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

66 bool "Versatile Express Serial Power Controller (SPC)"
69 The TC2 (A15x2 A7x3) versatile express core tile integrates a logic
70 block called Serial Power Controller (SPC) that provides the interface
71 between the dual cluster test-chip and the M3 microcontroller that
72 carries out power management.
