	Say Y here to boot in secure mode by default even if non-secure mode
	is supported. This option is useful to boot kernels which do not
	suppport booting in non-secure mode. Only set this if you need it.
	This can be overridden at run-time by setting the bootm_boot_mode env.

	  The maximum number of CPUs supported in the PSCI firmware.
	  It is no problem to set a larger value than the number of
	  CPUs in the actual hardware implementation.

	---help---
	Say Y here to use the long descriptor page table format. This is
	required if U-Boot runs in HYP mode.
