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:

Author: Xiang Xiao <xiaoxiang@pinecone.net>
    include/nuttx/b2c.h and libx/libc/string:  Add non-standard string functions to deal with cases where there are more than 8-bits in a type char.

Author: Gregory Nutt <gnutt@nuttx.org>
    Fix several build issues/missing definitiona needed for OpenAMP build in drivers/.
    Add OpenAMP code has been reviewed and ran through tools/nxstyle (with all reports accounted for).

Author: Xiang Xiao <xiaoxiang@xiaomi.com>
    tools/:  Fix the minor issue in Makefile

Author: Gregory Nutt <gnutt@nuttx.org>
    drivers/rptun/rptun.c:  Review for coding standard.  Run against tools/nxstyle.
    tools/LibTargets.mk:  Fix some TABs that were turned into spaces by a copy-paste.
    fs/hostfs:  Add configure and build support for hostfs RPC.
    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.

5f37226b6d tools/ Make fragments: Fix the various minor issue for NUTTXLIBS/USERLIBS
1. Remove libcxx duplication in FlatLibs.mk and from kernel space
2. Remove libpass1 from KernelLibs.mk since kernel build doesn't support the two pass mode
3. Remove FSDIR related comment since file system cannot be disabled now

8e74365b96 ibs/libc, libs/symtab, tools/ build system: Move symbol table generation into libc since the address in symbol table should come from userspace binary for protect build, not kernel binary. 2019-09-28 11:14:48 -06:00

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

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.

Move boards to boards folder

* boards: rename configs folder to boards

    This is the proposed layout after the change:

    boards: - folder containing board folders
            <board>: - name of each board
                    drivers: - extra drivers specific for platform
                    include: - header files for the boars
                    scripts: - extra scripts specific for platform
                        src: - board specific code
                      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.

a64869aa67 CONFIG_NFILE_DESCRIPTORS=0 can no longer be used to disable the file system. NuttX with no file system does not make sense.
Squashed commit of the following:

    configs/:  The few configurations that formerly set CONFIG_NFILE_DESCRIPTORS=0 should not default, rather they should set the number of descriptors to 3.
    fs/:  Remove all conditional logic based on CONFIG_NFILE_DESCRIPTORS == 0
    tools/:  Tools updates for changes to usage of CONFIG_NFILE_DESCRIPTORS.
    syscall/:  Remove all conditional logic based on CONFIG_NFILE_DESCRIPTORS == 0
    libs/:  Remove all conditional logic based on CONFIG_NFILE_DESCRIPTORS == 0
    include/:  Remove all conditional logic based on CONFIG_NFILE_DESCRIPTORS == 0
    drivers/:  Remove all conditional logic based on CONFIG_NFILE_DESCRIPTORS == 0

4becaea8e3 This commit extends support for the two-pass build. Its primary purpose is to incorporate source logic generated by applications into the kernel phase of the build.
In the two pass build, the application logic is built during the first phase, pass 1.  In that phase, the application may generate and install source files in the pass1/directory.  The operating system is built during phase 2 of the build.  At that time, those source files in the pass1/ directory will be built and incorporated into the kernel address space.

The primary purpose of the pass1/ directory is to such application-generated kernel symbol tables.  For an example of the use of this feature, look at apps/examples/module/drivers/Makefile.  Kernel symbol tables are needed to support kernel modules.  Of course, addition board-specific logic in, say, configs/<board>/src would have to be included to make use of the application-installed symbol tables.
