Select this option only with the boards/z20x/sdboot
configuration. This will enable the components needed only by the
boot loader.

Select this option only with the boards/z20x/w25boot
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"
depends on 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"
depends on 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.

depends on Z20X_W25BOOT
---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.
