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).

Add test sptests/spsysinit01.
Update #2408.
Call bsp_work_area_initialize() before bsp_start(). This allows
bsp_start() to use malloc() etc. which is beneficial for systems with a
plug-and-play hardware enumeration.
Update #2408.
Do not return from rtems_initialize_start_multitasking() and call
rtems_fatal() instead with a fatal source of RTEMS_FATAL_SOURCE_EXIT and
a fatal code with the exit status.
Remove all bsp_cleanup() functions. The boot_card() is now a no return
function.
The work areas (RTEMS work space and C program heap) will be initialized
now in a separate step and are no longer part of
rtems_initialize_data_structures(). Initialization is performed with
tables of Heap_Area entries. This allows usage of scattered memory
areas present on various small scale micro-controllers.
The sbrk() support API changes also. The bsp_sbrk_init() must now deal
with a minimum size for the first memory chunk to take the configured
work space size into account.
Script does what is expected and tries to do it as
smartly as possible.
+ remove occurrences of two blank comment lines
next to each other after Id string line removed.
+ remove entire comment blocks which only exited to
contain CVS Ids
+ If the processing left a blank line at the top of
a file, it was removed.
PR 1824/cpukit
* bootcard.c, bspclean.c, include/bootcard.h: Return exit/shutdown
status back to boot_card(). boot_card() propagates this to
bsp_cleanup() and returns it to the assembly that started the
application.
* bootcard.c, bspgetworkarea.c, include/bootcard.h: Switch from ssize_t
to uintptr_t for bsp_get_work_area() since the work area is larger
than a single allocatable object.
* bootcard.c, bspgetworkarea.c, bsppretaskinghook.c,
include/bootcard.h: Change size_t to ssize_t on bsp_get_work_area().
On 16-bit architectures, size_t can be 16-bits which would limit the
work area to 64K.
* bootcard.c, include/bootcard.h: Make letting boot_card() handle work
area allocation mandatory. Rename
RTEMS_BSP_BOOTCARD_HANDLES_RAM_ALLOCATION to BSP_BOOTCARD_OPTIONS.
* bspclean.c, include/bootcard.h: Use standardized bsp_cleanup() which
can optionally print a message, poll for user to press key, and call
bsp_reset(). Using this eliminates the various bsp_cleanup()
implementations which had their own implementation and variety of
string constants.
* bspreset.c, bspreset_fatal.c, bspreset_loop.c: New files.
