	help
	  Describes the total size of the MCU MSRAM. This doesn't
	  specify the total size of SPL as ROM can use some part
	  of this RAM. Once ROM gives control to SPL then this
	  complete size can be usable.

	  Address at which ROM stores the value which determines if SPL
	  is booted up by primary boot media or secondary boot media.

config SYS_K3_KEY
	string "Key used to generate x509 certificate"
	help
	  This option enables to provide a custom key that can be used for
	  generating x509 certificate for spl binary. If not needed leave
	  it blank so that a random key is generated and used.

config K3_EARLY_CONS
	bool "Activate to allow for an early console during SPL"
	depends on SPL
	help
	  Turn this option on to enable an early console functionality in SPL
	  before the main console is being brought up. This can be useful in
	  situations where the main console is dependent on System Firmware
	  (SYSFW) being up and running, which is usually not the case during
	  the very early stages of boot. Using this early console functionality
	  will allow for an alternate serial port to be used to support things
	  like UART-based boot and early diagnostic messages until the main
	  console is ready to get activated.

config K3_EARLY_CONS_IDX
	depends on K3_EARLY_CONS
	int "Index of serial device to use for SPL early console"
	default 1

	  Use this option to set the index of the serial device to be used
	  for the early console during SPL execution.

	  Address on the MMC to load the combined System Firmware and
	  configuration image tree blob from, when the MMC is being used
	  in raw mode. Units: MMC sectors (1 sector = 512 bytes).

config K3_SYSFW_IMAGE_SIZE_MAX

	default	277000
	help
	  Amount of memory (in bytes) reserved through dynamic allocation at
	  runtime for loading the combined System Firmware and configuration image
	  tree blob. Keep it as tight as possible, as this directly affects the
	  overall SPL memory footprint.

config SYS_K3_SPL_ATF
	bool "Start Cortex-A from SPL"
	depends on SPL && CPU_V7R
	help
	  Enabling this will try to start Cortex-A (typically with ATF)
	  after SPL from R5.
