Adds -fno-strict-aliasing to ARCHOPTIMIZAITON definition for all sim Make.defs file. This is constistent with the setting used in the Make.defs file of all other architectures and should eliminate the build test warnings:
arp/arp_arpin.c: In function 'arp_arpin':
arp/arp_arpin.c:136:13: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing]
net_ipv4addr_hdrcopy(arp->ah_sipaddr, &dev->d_ipaddr);
^~~~~~~~~~~~~~~~~~~~
arp/arp_format.c: In function 'arp_format':
arp/arp_format.c:96:3: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing]
net_ipv4addr_hdrcopy(arp->ah_dipaddr, &ipaddr);
^~~~~~~~~~~~~~~~~~~~
And similar warnings from icmp/icmp_input.c, and tcp/tcp_send.c. -fno-strict-aliasing i required for a warning free build of NuttX code since there is use of punned pointers.
arch/z80/src/ez80/ez80_timerisr.c: Fix an error that looks the file got damaged by a bad keystroke in the editor while a string was highlighted.
boards/z80/ez80/z20x/src/ez80_spi.c: Fix some bad conditional compilationi. Prevented W25 chip select from being initialized.
This reverts commit f735584514.
These header changes introduce unacceptable errors:
1. The changes alter the width of the initial block comment. That will cause nxstyle failures on most of the files.
2. The third line of the header is an (optional) short description of content of the the file. This change erroneously removes that line.
Automated header file changes can screw up a lot of files, very quickly.
Commit 797e45d6bf attempted to reduce the frequency of SPI reconfiguration by keeping track of the current frequency and mode settings and changing these settings only when the new settings differ from the old settings.
However, the original commit neglected to save the new frequency setting and, hence, was not effective in what it was trying to do: Every time the SPI setfrequency() method was called, it still looked like a new frequency and the frequency was still reconfigured, even though it hadn't really changed.
arch/z80/src/ez80/ez80_spi.c: Do not configure SPI chip select pin. It is not used by the driver and configuring it just clobbers other usage of that pin. Add some additional debug outputs; correct some exiting debug outputs.
drivers/mtd/w25.c: Add some debug output.
boards/z80/ez80/z20x/src/ez80_w25.c: Correct SPI bus number used in initialization. Only SPI1 is supported.
arch/z80/src/ez80/ez80_timerisr.c: Some initial timer configuration fixes.
* 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
The SPECIFIC_DRIVERS configuration was removed from the drivers Kconfig and
the build will ignore the specific drivers.
This patch enables the config locally for the CXD56 board

This sensor driver needs rework to match the needed layout for standar NuttX driver.
In the meantime it is moved to board specific sensors to fix the violation.

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.
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.
* imxrt: GPIO make tables const
* imxrt: Call out to board to set up FlexRAM

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.
The eZ80F92 interrupt controller is very different from the eZ80F91. The eZ80F91 has:
1. Four byte interrupt vectors
2. The vector base address register is 16-bit so the vector table can lie in RAM
Whereas the eZ80F92 has:
1. Two byte interrupt vectors
2. An 8-bit vector base address
This means that the vectors must lie in the first 16-bits of FLASH and there must be a "trampoline" to get to interrupt handlers outside of the first 64-Kb of FLASH.
arch/z80/src/ez80/Toolchain.defs: Correct some CFLAGS when optimization suppressed.
arch/z80/src/ez80/Kconfig arch/z80/src/ez80/ez80_emac.c: Remove configuration option for selecting EMAC RAM address. This is duplicated and possibly conflicting. The correct address for the RAM is provided in the linker command file. The RAM should be configured once and using this single definitions.
arch/z80/src/ez80/ez80_startup.asm and arch/z80/src/ez80/ez80f9*_init.asm. Move RAM and FLAH intialization out of MCU-specific logic to common start-up logic. We cannot call any functions until SRAM is initialized and the stack is properly initialized because the return address is stored on the stack. Use internal SRAM for the IDLE stack to avoid the chicken'n'egg problem.
boards/z80/ez80/z20x/configs/sdboot/sdboot.zdsproj: Discuss build environments.
CONFIG_FAT_MAXFNAME is set to 255 and CONFIG_NAME_MAX is set to 765
