		Select this option only with the boards/z20x/sdboot

		boot loader.

		configuration.  This will enable the components needed only by the
		boot loader.

config Z20X_PROGRAM
	bool "Loadable program"
	select EZ80_PROGRAM
	---help---
		Normal program that resides on SD card or in W25 FLASH and is
		loaded into RAM by a bootloader.

config Z20X_STANDALONE
	bool "Standalone FLASH progroam"
	select BOOT_RUNFROMFLASH
	---help---
		Select this option only to build a small program that executes
		from z20x FLASH memory.

config Z20X_COPYTORAM
	bool "Copy to RAM"
	select BOOT_RUNFROMEXTSRAM
	---help---
		This option is available only when running from external SRAM
		(CONFIG_BOOT_RUNFROMEXTSRAM).  In that case there are two possible
		options:  (1) The configuration runs entirely out of SRAM and must
		be copied into SRAM by a boot loader.  Or (2) The configuration
		boots out of FLASH, copies itself to SRAM, and runs from SRAM.  This
		configuration setting selects that latter option.

	---help---
		This is the size of the partition at the beginning to the W25
		serial FLASH that will be used to hold the boot program.  Since
		this program must run from SRAM, there would be no purpose int
		making this size any larger than the size of the internal SRAM.
