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.

48 Provides common dependencies for Versatile Express platforms
49 based on Cortex-A5 and Cortex-A9 processors. In order to
50 build a working kernel, you must also enable relevant core
51 tile support or Flattened Device Tree based support options.
53 config ARCH_VEXPRESS_DCSCB
54 bool "Dual Cluster System Control Block (DCSCB) support"
56 select ARM_CCI400_PORT_CTRL
58 Support for the Dual Cluster System Configuration Block (DCSCB).
59 This is needed to provide CPU and cluster power management
60 on RTSM implementing big.LITTLE.
62 config ARCH_VEXPRESS_SPC
63 bool "Versatile Express Serial Power Controller (SPC)"
66 The TC2 (A15x2 A7x3) versatile express core tile integrates a logic
67 block called Serial Power Controller (SPC) that provides the interface
68 between the dual cluster test-chip and the M3 microcontroller that
69 carries out power management.

72 bool "Versatile Express TC2 power management"
74 select ARM_CCI400_PORT_CTRL
75 select ARCH_VEXPRESS_SPC
76 select ARM_CPU_SUSPEND
78 Support for CPU and cluster power management on Versatile Express
79 with a TC2 (A15x2 A7x3) big.LITTLE core tile.
