* shared/bspgetworkarea.c: 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.
* configure.ac: Make letting boot_card() handle work area allocation
mandatory. Rename RTEMS_BSP_BOOTCARD_HANDLES_RAM_ALLOCATION to
BSP_BOOTCARD_OPTIONS.
* Makefile.am: bsp_cleanup() had the same code which was executed when
you returned from boot_card() to start.S. So just use the stub
bsp_cleanup() implementation and remove a file.
* shared/bspstart.c: Use shared bsp_get_work_area() in its own file and
rely on BSP Framework to perform more initialization.
* shared/bspgetworkarea.c: New file.
* include/bsp.h: Review of all bsp_cleanup() implementations. In this
phase, all prototypes were removed from bsp.h and empty
implementations were removed and made to use the shared stub.
* startup/linkcmds: All SPARC executables should include
rtems_get_version_string so the monitor used can provide RTEMS
awareness based upon the version.
* Makefile.am, configure.ac, startup/bspstart.c: Add capability for
bootcard.c BSP Initialization Framework to ask the BSP where it has
memory for the RTEMS Workspace and C Program Heap. These collectively
are referred to as work area. If the BSP supports this, then it does
not have to include code to split the available memory between the
two areas. This reduces the amount of code in the BSP specific
bspstart.c file. Additionally, the shared framework can initialize
the C Library, call rtems_debug_enable(), and dirty the work area
memory. Until most/all BSPs support this new capability, if the BSP
supports this, it should call
RTEMS_BSP_BOOTCARD_HANDLES_RAM_ALLOCATION from its configure.ac. When
the transition is complete, this autoconf macro can be removed.

Initialization Framework to ask the BSP where it has memory for the
RTEMS Workspace and C Program Heap. These collectively are referred

include code to split the available memory between the two areas.

* startup/bspstart.c: Refactored and renamed initialization routines to
rtems_initialize_data_structures, rtems_initialize_before_drivers,
rtems_initialize_device_drivers, and
rtems_initialize_start_multitasking. This opened the sequence up so
that bootcard() could provide a more robust and flexible framework
which is easier to explain and understand. This also lays the
groundwork for sharing the division of available memory between the
RTEMS workspace and heap and the C library initialization across all
BSPs.
