The versatile express changes for 3.16 introduced a number of build regressions for randconfig kernels by not tracking dependencies between the components right. This patch tries to rectify that: * the mach-vexpress code cannot link without the syscfg driver, which in turn needs MFD_VEXPRESS_SYSREG * various drivers call devm_regmap_init_vexpress_config(), which has to be exported so it can be used by loadable modules * the configuration bus uses OF DT helper functions that are not available to platforms disable CONFIG_OF * The sysreg driver exports GPIOs through gpiolib, which can be disabled on some platforms. * The clocksource code cannot be built on platforms that don't use modern timekeeping but rely on gettimeoffset.

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)

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