459ad99373 Use EXTRAFLAGS instead of EXTRADEFINES to be used by make via command line
So call 'make EXTRAFLAGS=-Wno-cpp' could suppress the warnings with pre-processor
directive #warning in GCC.

3ee1af5bcc Build System: Resolve CPU-specific logic in common build files
* tools/Config.mk - Add empty definition POSTBUILD
* tools/Makefile.unix/win - Replace CXD56xx specific logic with $(call POSTBUILD)
* boards/arm/cxd56xx/scripts/Config.mk - Add POSTBUILD definitions with logic removed from Makefile.unix/win
* boards/arm/cxd56xx/spresense/scripts/Make.defs - Include the CXD56xx Config.mk immediately after tools/Config.mk so that the empty POSTBUILD definition will be replaced with the correct one

NOTE: There is a precedent for this approach.  This is the way that other architecture-specific build options are implemented.  See, for example, tools/zds/Config.mk

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.

e814977c0f boards/z80/ez80/z20x/: Add W25 bootloader
The SD boot loader was not satisfactory because 1) the SD slot is on an optional board and, hence, cannot be part of a fundamental solution.  And 2) it is too big.

The only storage on borard is the Winbond W25 SPI-bsed FLASH.  This commit adds support for a bootload to 1) read code in HEX format from a serial port and write it to the W25 FLASH, or 2) read code in binary form from the W25 FLASH into SRAM and execute the loaded program.

boards/z80/ez80/z20x/configs:  Added w25boot configuration
boards/z80/ez80/z20x/src:  Add bootloader logic, w25_main.c.  Add logic to manage shared SRAM memory map so that the loaded program does not clobber the bootloader memory.  Add logic to recover the bootloader memory into the heap after the loaded program as started.
boards/z80/ez80/z20x/scripts:  Rework scripts and configuration to support a bootloader and program build.  The boolloader cannot use all of SRAM; the program must not clobber the SRAM region used by the bootloader.

41ef33bded eZ80: Fix optimization issues
board/z80/ez80/*/scripts/Make.defs:  Fix optimization definition use in assembly flags.  It was using the compiler optimization settings instead of the assembler optimization settings.  Hence, enabling optimization would could cause assembler command line errors.

arch/z80/src/ez80/Toolchain.defs:  Back out some work arounds.  Now compiler optimization flags can again set set without assembler command line errors.

boards/z80/ez80/z20x/README.txt:  Trivial update to size/optimization discussion.

a9610e16bd boards/z80/ez80/z20x: Update CFLAGS and linker scripts.
arch/z80/src/ez80/Toolchain.defs:  Update some CFLAGS to match CFLAGS from ZDS-II IDE.  Apparently, we must say that the CPU is an eZ80F91 event when compiler for eZ80F92.
boards/z80/ez80/z20x:  Update linker scripts.

e6f545beab Extend revised ZDS-II support to z8 and z16f
* tools/zds/zds_Config.mk: Move  boards/z80/ez80/scripts/eZ80_Config.mk to tools/zds/zds_Config.mk where it can be shared by other ZDS-II platforms.
* boards/z16/z16f:  Duplicate changes for new ZDS-II support from ez80
* boards/z80/z8:  Duplicate changes for new ZDS-II support from ez80
* arch/z16/src/z16f/Toolchain.defs:  Create required Toolchain.defs file for Z16f

7516f76422 boards/z80/ez80: More consolidation of build files.
arch/z80/arc/ez80/Toolchain.sh:  Move more common toolchain definitions from Make.defs.
boards/z80/ez80/scripts/eZ80_Config.mk:  Move common defines that override tools/Config.mk to this new file.

This does not solve the ez80 build problem yet but does assure that when the solution is in place, it will automatically apply to all present and future ez80 configurations.
