Gregory Nutt 2eff5a6c63 z20X: Continued development of the W25 Bootloader.
Kconfig files.  Repartition some functionality.  Bootloader support will need to be provided in logic under arch/z80/src/ez80 so the critical configuration selections were moved the Kconfig file there.

arch/z80/src/ez80/ez80_i2c.h:  Rename arch/z80/src/ez80/ez80f91_i2c.h.  It is sharable by both ez80f91 and ez80f92.

arch/z80/src/ez80/:  Add logic to perform an additional level of interrupt redirection.  This is necessary because the the interrupt handling is part of the loader FLASH-based logic.  In order to share interrupts with the program loaded into RAM by the loader, another layer or redirection is required to get control to the interrupt handlers in the loaded program.  See ez809f2_loader.asm and ez80f92_program.asm

boards/z80/ez80/z20x/scripts:  Reduce size of the interrupt re-direction buffer from 1Kb to 512b.

if ARCH_BOARD_MAKERLISP
config MAKERLISP_VGA
bool "VGA Controller attached?"
default n
---help---
Select this option if you have an I/O Controller and a VGA vide card
connected.
config MAKERLISP_COPYTORAM
bool "Copy to RAM"
default n
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.
config MAKERLISP_SDBOOT
bool "Build SD boot loader"
default n
select EZ80_BOOTLOADER
---help---
Select this option only with the boards/makerlisp/sdboot
configuration. This will enable the components needed only by the
boot loader.
