	  Describes the total size of the MCU or OCMC MSRAM present on

	  ROM can use some part of this RAM. Once ROM gives control to
	  SPL then this complete size can be usable.

	  This option enables to provide a custom key that can be used for

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

config K3_SYSFW_IMAGE_SIZE_MAX
	int "Amount of memory dynamically allocated for loading SYSFW blob"
	depends on K3_LOAD_SYSFW
	default	278000
	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 K3_SYSFW_IMAGE_SPI_OFFS
	hex "SPI offset of SYSFW firmware and configuration blob"
	depends on K3_LOAD_SYSFW
	default	0x6C0000

	  Offset of the combined System Firmware and configuration image tree
	  blob to be loaded when booting from a SPI flash memory.

config SYS_K3_SPL_ATF
	bool "Start Cortex-A from SPL"
	depends on SPL && CPU_V7R

	  Enabling this will try to start Cortex-A (typically with ATF)

config K3_ATF_LOAD_ADDR
	hex "Load address of ATF image"

	depends on SPL && CPU_V7R && (SOC_K3_J721E || SOC_K3_J721S2) && !CLK_TI_SCI && !TI_SCI_POWER_DOMAIN
	default y
	help
	  Enabling this will indicate that the system has separate DM
	  and TIFS firmware images in place, instead of a single SYSFW
	  firmware. Due to DM being executed on the same core as R5 SPL
	  bootloader, it makes RM and PM services not being available
	  during R5 SPL execution time.
