* startup/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, configure.ac, startup/bspstart.c: Add
bsp_get_work_area() implementation and use more of the BSP
Initialization Framework.
* startup/bspgetworkarea.c, startup/bsppost.c: New files.
* 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.
* clock/clock.c: The Shared Memory Driver no longer requires the
special IOCTL in Clock_control. This was a hack which has existed
since before the Classic API Timer Manager was implemented. All
implementations of and references to Clock_control were removed.
* 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.
* 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.
* clock/clock.c, include/bsp.h, startup/bspstart.c,
startup/rtems-ctor.cc: Eliminate copies of the Configuration Table.
Use the RTEMS provided accessor macros to obtain configuration
fields.
* include/bsp.h, startup/bspstart.c: Move interrupt_stack_size field
from CPU Table to Configuration Table. Eliminate CPU Table from all
ports. Delete references to CPU Table in all forms.
* startup/bspstart.c: Moved most of the remaining CPU Table fields to
the Configuration Table. This included pretasking_hook,
predriver_hook, postdriver_hook, idle_task, do_zero_of_workspace,
extra_mpci_receive_server_stack, stack_allocate_hook, and
stack_free_hook. As a side-effect of this effort some multiprocessing
code was made conditional and some style clean up occurred.
* Makefile.am, startup/main.c: Now can link with C compiler and not
require C++ compiler to link. The file rtems-ctor.cc is not being
built but if there is a need for C++ code to run on this BSP, then it
will have to be addressed. The simplest solution which might work is
to check the RTEMS system state before calling bsp_start() in main().
