I've trimmed my platform Kconfig down to:

config ARCH_TANGO4
	bool "Sigma Designs Tango4 (SMP87xx)"
	default y
	select ARCH_HAS_HOLES_MEMORYMODEL
	select ARM_ERRATA_754322
	select ARM_ERRATA_764369
	select ARM_GIC
	select CACHE_L2X0
	select CLKSRC_MMIO
	select GENERIC_IRQ_CHIP
	select HAVE_ARM_SCU
	select HAVE_ARM_TWD
	select NEON
	select SMP


Didn't find much documentation on ARCH_HAS_HOLES_MEMORYMODEL.
What is it used for?

http://cateee.net/lkddb/web-lkddb/ARCH_HAS_HOLES_MEMORYMODEL.html

Is it OK to select CACHE_L2X0, NEON, and SMP?

Regards.
