Make rtems_initialize_data_structures(), rtems_initialize_before_drivers() and rtems_initialize_device_drivers() static. Rename rtems_initialize_start_multitasking() to rtems_initialize_executive() and call the registered system initialization handlers in this function. Add system initialization API available via #include <rtems/sysinit.h>. Update the documentation accordingly. This is no functional change, only the method to call the existing initialization routines changes. Instead of direct function calls a table of function pointers contained in the new RTEMS system initialization linker set is used. This table looks like this (the actual addresses depend on the target). nm *.exe | grep _Linker | sort 0201a2d0 D _Linker_set__Sysinit_begin 0201a2d0 D _Linker_set__Sysinit_bsp_work_area_initialize 0201a2d4 D _Linker_set__Sysinit_bsp_start 0201a2d8 D _Linker_set__Sysinit_rtems_initialize_data_structures 0201a2dc D _Linker_set__Sysinit_bsp_libc_init 0201a2e0 D _Linker_set__Sysinit_rtems_initialize_before_drivers 0201a2e4 D _Linker_set__Sysinit_bsp_predriver_hook 0201a2e8 D _Linker_set__Sysinit_rtems_initialize_device_drivers 0201a2ec D _Linker_set__Sysinit_bsp_postdriver_hook 0201a2f0 D _Linker_set__Sysinit_end Add test sptests/spsysinit01. Update #2408.
