config ARCH_RAMFUNCS
	bool "Copy functions to RAM on startup"
	default n
	depends on ARCH_HAVE_RAMFUNCS
	---help---
		Copy some functions to RAM at boot time.  This is done in some
		architectures to improve performance.  In other cases, it is done
		so that FLASH can be reconfigured while the MCU executes out of
		SRAM.

comment "Board Settings"

config BOARD_LOOPSPERMSEC
	int "Delay loops per millisecond"
	default 5000
	---help---
		Simple delay loops are used by some logic, especially during boot-up,
		driver initialization.  These delay loops must be calibrated for each
		board in order to assure accurate timing by the delay loops.

config ARCH_CALIBRATION
	bool "Calibrate delay loop"
	default n
	---help---
		Enables some built in instrumentation that causes a 100 second delay
		during boot-up.  This 100 second delay serves no purpose other than it
		allows you to calibratre BOARD_LOOPSPERMSEC.  You simply use a stop
		watch to measure the actual delay then adjust BOARD_LOOPSPERMSEC until
		the actual delay is 100 seconds.

config DRAM_START
	hex "DRAM start physical address"
	help
		The physical start address of installed RAM.  Despite the naming,
		this may be SDRAM or SRAM or any other RAM technology that support
		program execution.

config DRAM_VSTART
	hex "DRAM start virtual address"
	depends on ARCH_HAVE_MMU
	help
		The virtual start address of installed RAM.  Despite the naming,
		this may be SDRAM or SRAM or any other RAM technology that support
		program execution.

config DRAM_SIZE

	help
		The size in bytes of the installed RAM.  Despite the naming,
		this may be SDRAM or SRAM or any other RAM technology that support
		program execution.

	bool

config ARCH_INTERRUPTSTACK
	int "Interrupt Stack Size"
	depends on ARCH_HAVE_INTERRUPTSTACK
	default 0
	---help---
		This architecture supports an interrupt stack. If defined, this symbol
		will be the size of the interrupt stack in bytes.  If not defined (or
		defined to be zero), the user task stacks will be used during interrupt
		handling.

	---help---
		Some configuration support booting and running from external SRAM.

config BOOT_RUNFROMFLASH
	bool "Boot and run from flash"
	---help---
		Most configurations support XIP operation from FLASH but must copy
		initialized .data sections to RAM. (This is the default).

config BOOT_RUNFROMISRAM
	bool "Boot and run from internal SRAM"
	---help---
		Some configuration support booting and running from internal SRAM.

config BOOT_RUNFROMSDRAM
