Fix #285, Refactor OSAL to avoid inclusion of C files
Use separate source files and CMake-based source selection based on feature configuration, rather than using the C preprocessor for including/excluding different OSAL function groups. Refactor all implementation units to provide a separate header file for each functional group/subsystem. Remove "static" declaration on internal helper functions so they can be invoked from unit test.

| # Default configuration options for OSAL | ||
| # | ||
| # This file specifies the default values for various compile-time options | ||
| # supported by OSAL. These options can be further tuned by the specific | ||
| # OSAL and BSP selection, as well as the user application. | ||
| # | ||
| # NOTE: | ||
| # The defaults in this file should _not_ be directly modified for tuning. | ||
| # | ||
| # Instead, use the "OSAL_CONFIGURATION_FILE" CMake variable to define | ||
| # a custom file which can override/modify the configuration for the items | ||
| # which require tuning. | ||

| # OSAL_CONFIG_INCLUDE_NETWORK | ||
| # ---------------------------------- | ||
| # | ||
| # Whether to include the Network API | ||
| # | ||
| # If set TRUE, the the socket abstraction (if applicable on the platform) | ||
| # will be included. If set FALSE, then all calls to the network API will | ||
| # return OS_ERR_NOT_IMPLEMENTED. | ||
| # | ||
| # This can be set FALSE for platforms which do not have a network or | ||
| # IP stack available, or to save code space if the application does | ||
| # not use network resources. | ||
| # | ||
| set(OSAL_CONFIG_INCLUDE_NETWORK TRUE) | ||
|
|
||
|
|
||
| # | ||
| # OSAL_CONFIG_INCLUDE_DYNAMIC_LOADER | ||
| # ---------------------------------- | ||
| # | ||
| # Whether to include the capability of loading dynamic code objects | ||
| # | ||
| # This is normally set TRUE to support modularized applications on | ||
| # platforms which have this capability. | ||
| # | ||
| # For deployments which are always statically linked, this may be set | ||
| # FALSE for a smaller library size and reduced linking requirements. | ||
| # | ||
| set(OSAL_CONFIG_INCLUDE_DYNAMIC_LOADER TRUE) | ||
|
|
||
|
|
||
| # | ||
| # OSAL_CONFIG_INCLUDE_STATIC_LOADER | ||
| # ---------------------------------- | ||
| # | ||
| # Whether to include a compatibility "loader" for statically-linked objects | ||
| # | ||
| # This feature allows applications normally written for dynamic module loading | ||
| # operate transparently in a static link environment. If this is set TRUE, | ||
| # then the application must supply an object named "OS_STATIC_SYMBOL_TABLE" that | ||
| # contains the names and addresses of statically-linked symbols that should | ||
| # be known to the lookup/load functions. | ||
| # | ||
| # Note that modules "loaded" using this abstraction are still assigned a | ||
| # module ID and still require a slot in the module table even though | ||
| # no actual runtime loading is performed (see OSAL_CONFIG_MAX_MODULES). | ||
| # | ||
| set(OSAL_CONFIG_INCLUDE_STATIC_LOADER TRUE) | ||
|
|
||
| # | ||
| # OSAL_CONFIG_INCLUDE_SHELL | ||
| # ---------------------------------- | ||
| # | ||
| # Whether to include features which utilize the operating system shell. | ||
| # | ||
| # Remote Shell commands can be very powerful tool for remotely diagnosing | ||
| # and mitigating runtime issues in the field, but also have significant | ||
| # security implications. If this is set to "false" then shell functionality | ||
| # is disabled and OSAL functions which invoke the shell will return | ||
| # OS_ERR_NOT_IMPLEMENTED. | ||
| # | ||
| set(OSAL_CONFIG_INCLUDE_SHELL FALSE) | ||
|
|
||
|
|
||
| # | ||
| # OSAL_CONFIG_DEBUG_PERMISSIVE_MODE | ||
| # ---------------------------------- | ||
| # | ||
| # The OSAL_CONFIG_DEBUG_PERMISSIVE_MODE option controls how privileged operations | ||
| # are handled by the OSAL in the event that the user does not have sufficient permission. | ||
| # In particular this applies to task priorities and message queues. | ||
| # | ||
| # If set FALSE, then all permissions are enforced, and a failure due to lack of permission | ||
| # will cause a failure of the overall operation, which is passed back to the application. | ||
| # | ||
| # If set to TRUE, this will treat some errors non-fatal and enable a graceful fallback, | ||
| # allowing the overall operation to complete in a reduced form. This makes the | ||
| # OSAL library compatible with a non-root (normal user mode) environment. | ||
| # | ||
| # In the PC-Linux/Posix build, this means: | ||
| # - A message queue deeper than the maximum system limit will be silently truncated | ||
| # to the maximum system limit (no error). | ||
| # - If the user does not have permission to create elevated priority tasks, then the tasks will | ||
| # be created at the default priority (no error). | ||
| # | ||
| set(OSAL_CONFIG_DEBUG_PERMISSIVE_MODE FALSE) | ||
|
|
||
| # | ||
| # OSAL_CONFIG_DEBUG_PRINTF | ||
| # ---------------------------------- | ||
| # | ||
| # Controls inclusion of OS_DEBUG statements in the code | ||
| # | ||
| # If set FALSE, all OS_DEBUG statements are compiled out. | ||
| # | ||
| # If set TRUE, all the "OS_DEBUG" statements will be compiled in and displayed | ||
| # on the debug console. The statements may still be suppressed at runtime. | ||
| # | ||
| set(OSAL_CONFIG_DEBUG_PRINTF FALSE) | ||
