b88561299b make/expression: improving up asm/C/C++ compile times
In the current compilation environment, the recursive assignment(=) for compile
flags will be delayed until every file is actually need to be compile.

For example:
--------------------------------------------------------------------------------
arch/arm/src/Makefile:

INCLUDES += ${shell $(INCDIR) "$(CC)" $(ARCH_SRCDIR)$(DELIM)chip}
INCLUDES += ${shell $(INCDIR) "$(CC)" $(ARCH_SRCDIR)$(DELIM)common}
INCLUDES += ${shell $(INCDIR) "$(CC)" $(ARCH_SRCDIR)$(DELIM)$(ARCH_SUBDIR)}
INCLUDES += ${shell $(INCDIR) "$(CC)" $(TOPDIR)$(DELIM)sched}

CPPFLAGS += $(INCLUDES) $(EXTRAFLAGS)
CFLAGS += $(INCLUDES) $(EXTRAFLAGS)
CXXFLAGS += $(INCLUDES) $(EXTRAFLAGS)
AFLAGS += $(INCLUDES) $(EXTRAFLAGS)
--------------------------------------------------------------------------------

All compilation options will be included recursively,
which will be delayed until the compilation options are actually used:

tools/Config.mk:

--------------------------------------------------------------------------------
define COMPILE
  @echo "CC: $1"
  $(Q) $(CC) -c $(CFLAGS) $($(strip $1)_CFLAGS) $1 -o $2
endef
--------------------------------------------------------------------------------

All compile flags to be reexecuted $(INCDIR) as long as one file needs to be compiled,
but in fact, the compilation options have not changed in the current directory.

So the we recommand to change the syntax of assignment
From
    Recursive (=)
To
    Simple    (:=)

In this way, we can ensure that all compilation options are expanded only once and reducing repeated works.

e249a2f82f Makefile: Fix Make.dep not updated by config changes
Make.dep file should be updated by .config changed after first make.
There are 2 cases affected for this problem:

 1) Add source files by config symbol
 2) Include header files in #ifdef directive

These 2 cases may not be included in Make.dep and this may prevent the
differential build from working correctly.

- Remove per-thread errno from the TCB structure (pterrno)
- Remove get_errno() and set_errno() as functions.  The macros are still available as stubs and will be needed in the future if we need to access the errno from a different address environment (KERNEL mode).
- Add errno value to the tls_info_s structure definitions

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.

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.

8c00e43c1a arch/z80/src/ez80: Fix eZ80F92 Interrupt Controller
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.

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.

With this change, the z20x board FINALLY builds and links correctly with no errors.

The ez80f92 is similar to the currently supported ez80f91 except that is:

1. Has no PLL and has a maximum CPU frequency of only 20MHz
2. Has no Ethernet controller
3. Timers are different
4. Has no GPIO Port A
5. Timers are different
6. It comes in a smaller package

and other small differences.

This provided the architecture (only) support for the forthcoming z20x port.

6d69439f58 Call xxx_timer_initialize from clock subsystem
Call xxx_timer_initialize from clock subsystem to make timer ready for use as soon as possiblei and revert the workaround:

commit 0863e771a9
Author: Gregory Nutt <gnutt@nuttx.org>
Date:   Fri Apr 26 07:24:57 2019 -0600

    Revert "sched/clock/clock_initialize.c:  clock_inittime() needs to be done with CONFIG_SCHED_TICKLESS and clock_initialize should skip clock_inittime() for external RTC case since the RTC isn't ready yet."

    This reverts commit 2bc709d4b9.

    Commit 2bc709d4b9 was intended to handle the case where up_timer_gettime may not start from zero case.  However, this change has the side-effect of breaking every implementation of tickless mode:  After this change the tickless timer structures are used before they are initialized in clock_inittime().  Initialization happens later when up_initialize is called() when arm_timer_initialize().

    Since the tickless mode timer is very special, one solution might be to

    1. Rename xxx_timer_initialize to up_timer_initialize
    2  Move up_timer_initialize to include/nuttx/arch.h
    3.  Call it from clock subsystem instead up_initialize

    Basically, this change make timer initialization almost same as rtc initialization(up_rtc_initialize).

    For now, however, we just need to revert the change.

87cf5c58ae Correct some problems with network timed events when there are multiple network devices in the configuration.
Squashed commit of the following:

Author: Gregory Nutt <gnutt@nuttx.org>

    Ran nxstyle against many of the affected files.  But this job was too big for today.  Many of the network drivers under arch are highly non-compiant and generate many, many faults from nxstyle.  Those will have to be visited again another day.

Author: Xiang Xiao <xiaoxiang@xiaomi.com>

    This effects all network drivers as well as timing related portions of net/: devif_poll_tcp_timer shouldn't be skipped in the multiple card case.  devif_timer will be called multiple time in one period if the multiple card exist, the elapsed time calculated for the first callback is right, but the flowing callback in the same period is wrong(very short) because the global variable g_polltimer is used in the calculation.  So let's pass the delay time to devif_timer and remove g_polltimer.

                    drivers: - extra drivers specific for platform

                      tools: - extra tools specific for platform
                    <config>: - board specific configuration(s)

    Note:
    <xxx> names are dependent on platform

    This is a logical change to aim to the arch layout but this is a
    huge change it should be done in several steps to lower the risk.

4e98980045 Add initial support for the MakerLisp eZ80 board. Ref: https://makerlisp.com/
Squashed commit of the following:

    configs/makerlisp:  Update comments about use of serial console.

    configs/makerlisp:  Add LED support, remove vestiges of button support (the board has no user buttons).  Add support for SPI-based MMC/SD card slot.

    arch/z80/src/ez80:  Fix some link problems.

    libs/libc/syslog/lib_syslog.c:  The ZDS-II toolchain does not declare va_coy in stdarg.h.  I think that the use of va_copy in vsyslog() is no necessary.

    configs/makerlisp:  Initial configuration directories cloned from ez80f910200zco with little more than naming changes.

Gregory Nutt
641a98a434 arch/: The saved return register state is available on the user stack. Thic commit reorders some logic so that certain, critical registers are preserved in the TCB. This does not make the logic 100% secure, but does prevent some obvious things. sched/signal/sig_delivery: Add a flag to the TCB to indicate that we are in a signal handler. Use this flag to assure that a there a never attempts to nest signal handling operations on a thread. This was guaranteed before but when locking of pre-emption during signal delivering was eliminated in a previous commit, there was a remote possibility of an attempt to do nested signal handling. This flag assures that there is only one signal handled at a time. 2019-02-03 15:29:47 -06:00
