config ARMV7R_HAVE_GICv2
	bool "ARMV7R_GICv2 support"
	default y
	---help---
		Selected by the configuration tool if the architecture supports the
		Generic Interrupt Controller (GIC)

config ARMV7R_MEMINIT
	bool
	default y if BOOT_SDRAM_DATA
	default n if !BOOT_SDRAM_DATA
	---help---
		If this configuration *not* selected, then it is assumed that all
		memory resources are initialized via arm_data_initialize() and
		available at power-up reset time.  Other memories, such as SDRAM or
		some ECC SRAM memories, require some platform-specific
		initialization first.  In that case, this option should be selected
		and the platform-specific implementation of arm_boot() must perform
		the memory initialization first, then explicitly call
		arm_data_initialize().

config ARMV7R_HAVE_L2CC
	bool
	default n
	---help---
		Selected by the configuration tool if the architecture supports any
		kind of L2 cache.

config ARMV7R_HAVE_L2CC_PL310
	bool
	default n
	select ARMV7R_HAVE_L2CC
	---help---
		Set by architecture-specific code if the hardware supports a PL310
		r3p2 L2 cache (only version r3p2 is supported).

		Enable the 2 Cache Controller (L2CC) is based on the L2CC-PL310 ARM
		multi-way cache macrocell, version r3p2.  The addition of an on-chip
		secondary cache, also referred to as a Level 2 or L2 cache, is a
		method of improving the system performance when significant memory
		traffic is generated by the processor.

		This choice specifies the associativity of L2 cache in terms of the

		about properties of the memory.
