	default y

		Selected by the configuration tool if the architecture supports the
		Generic Interrupt Controller (GIC)

	---help---
		Enable GICC_CTLR.EOImode, this will separates the priority drop and interrupt
		deactivation operations.

config ARMV7R_HAVE_PTM
	bool
	default n
	---help---
		Selected by the configuration tool if the architecture supports the
		per-processor Private Timers (PTMs)

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).

	---help---
		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
