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.

d1a8a803e4 Build system: Get rid of the MOVEOBJ definition
Eliminate the MOVEOBJ definition from tools/Config.mk, Makefiles, and other locations.  The MOVEOBJ definition was used to work around the case where the object output of a compile or assemble is in a different directory than the source file.  The ZDS-II tools have no command line option to perform this move; MOVEOBJ handled the move as a post-compiler operation.

MOVEOBJ is no longer needed because this the ez80 COMPILE and ASSEMBLE definitions now handle all of the object file movement cases.

PR317 removed definitions for SEC_PER_MIN, SEC_PER_HOUR, and SEC_PER_DAY because these were duplicates of definitions in include/nuttx/clock.h.  However, the PR did not include nuttx/clock.h so the removal of these definitions resulted in compilation failures.

81f1133174 ELF64 support (#220)
* include: Introduce elf64.h and elf.h

    Added elf64.h for 64bit ELF support and moved common definitions
    from elf32.h to elf.h. Also introduced Elf_xxx to be used in
    common libraries such as binfmt.

  * binfmt, include, modlib, module: Add support for ELF64

    Elf_xxx must be used instead of Elf32_xxx to support ELF64.
    To use ELF64, CONFIG_ELF_64BIT must be enabled.

  * binfmt, modlib: Add support for relocate address

  * arch: risc-v: Add include/elf.h

  * libs: machine: Add risc-v related files.

    NOTE: Currently only supports ELF64

  * boards: maix-bit: Add elf and posix_spawn configurations

  * boards: maix-bit: Add support for module configuration

8b92305265 This commit brings in the drivers needed to support OpenAMP. These changes were ported from https://github.com/FishsemiCode/nuttx. The current state: Most drivers do now compile but are not yet verfied.
This port was effort of a number of people, I rather arbitrarily gave authorship to Guiding Li because he has the largest number of fundamental quashed commits from the Xiamoi repository.

Squashed commit of the following:

    drivers/timer:  Add configure and build support for syslog RTC.
    drivers/syslog:  Add configure and build support for syslog RPC.
    drivers/serial:  Add configure and build support for serial RPC.
    Kconfig, tools/*.mk. openamp/:  Add basic OpenAMP build support.
    drivers/rptun:  Add configure and build support for OpenAMP tunnel drivers.
    drivers/net:  Update Make.defs and Kconfig for OpenSDA support.
    Remove drivers/clk/clk-rpmsg.c drivers/power/rpmsg_regulator.c.  These depend on upstreaming support for a new subsystem based on the clk/regulator is model from Linux.  Removed because we want to separate the activities.  We will just try to get the basic OpenAMP support in place for now.
    Remove drivers/misc/misc_rpmsg.c and include/nuttx/misc/misc_rpmsg.h.  These are specific to the Xiaomi application.

65aabe3048 libs/symtab: move symtab/ to libs/symtab. Let's no clutter up the top level directory. Shorten CONFIG_EXECFUNCS_GENERATE_SYSTEM_SYSTAB to just CONFIG_EXECFUNCS_SYSTEM_SYMTAB. Some items in syscall/syscall.csv are only valid when CONFIG_LIB_SYSCALL is defined. That is always defined when really building the syatem calls, but causes errors in libs/symtab because they are not valid in the normal, FLAT build context. 2019-08-25 19:28:04 -06:00

f751aff7fe boards/boardctl.c and libs/libc/builtin: The BINFS file system uses the same builtin library and builtin arrays as does NSH. The builtin arrays are simple name-value pairs that map builtin function names with the user-space entry point. In the FLAT build, the builtin arrays are available everywhere via the backdoor left open by the FLAT address space. In the PROTECTED build, however, the kernel must maintain its own reference to the user-space builtin array. This commits adds those kernel globals and a new boardctl(BOARDIOC_BUILTINS) that can be used by applications to the provide the builtin list reference to the kernel. 2019-08-25 16:58:43 -06:00

3c30cf1f05 Squashed commit of the following:
task_spawn() and posix_spawn() are NuttX OS interfaces.  In PROTECTED and KERNEL build modes, then can be reached from applications only via a system call.  Currently, the number of parameters in a system call is limited to six; these spawn function have seven parameters.  Rather than extend the maximum number of parameters across all architectures, I opted instead to marshal the seven parameters into a structure.
     *

In order to support builtin in function in protected mode, a task_spawn() system call must be supported.  Unfortunately this is overly complex because there is a (soft) limit of 6 parameters in a system call; task_spawn has seven paramters.  This is a soft limit but still difficult to extend because it involves assembly language changes to numerous architectures.  Better to get more creative.

dd97fb991b This commit moves shared builtin information out of binfmt/libbuiltin and into libs/libc/builtin where it can be shared. This should permit builtin application in the PROTECTED build where binfmt/libbuiltin is not available in user space.
Squashed commit of the following:

    Correct some additional compile-related issues.

    Move  include/nuttx/binfmt/builtin.h to include/nuttx/lib/builtin.h.  Move apps/builtin/lib_builtin_forindex.c to libs/libc/builtin/lib_builtin_forindex.c.

    Move binfmt/libbuiltin to libs/libc/builtin.  There are calls made directly from apps/nshlib into this logic and hence, must be part of a library that can be shared between the OS and applications.

380198c985 symtab/, tools/: NuttX provides lists of available syscalls and library functions and tools to process them. The lists can be used to build symbol table which allows runtime program loading which can reuse functions already compiled into NuttX system image. List processing, compilation and linking to the final system image has been possible only under manual control until now.
Provided changes add option (CONFIG_EXECFUNCS_GENERATE_SYSTEM_SYMTAB) to build complete list of available functions and syscalls automatically.  The symbolic table is generated in form libsymtab.a which can be reused by application or directly pull in when "g_symtab" and "g_nsymbols" variables are requested by EXECFUNCS configuration.

I have tried to follow mechanisms for library compilation in different kernel protection modes but tested only flat no-MMU build. The basic assumption is that this library and libraries providing syscall stubs and C-library functions are available in user-space context and initial application (usually NSH) registers the symbol table through IOCTL.  The table can be reused then by another applications in their address space as kernel allows. Simple for flat or protected mode, I am not sure if really support in MMU mode. It is highly probable that I have made some mistake, overlooked something, but functionality is optional (should not cause troubles in any mode if disabled) and main purpose is to lower memory overhead when more applications are loaded on memory constrained system which usually use direct kernel calling without protection or address space separation. If the table should be provided by kernel to applications then makefiles has to be adjusted.
