        * shared/irq_asm.S: From code inspection I have found the following
        issues (most SMP), and some improvements in irq_asm.S. I would need a
        long test with interrupts to verify the interrupt handler better,
        however I can not see that these patches hurt. Please see comment per
        hunk below, One should go through the file to indent delay-slots
        correctly, I have fixed some in the patch areas. An extra space is
        added in front of delay slots to indicate a delay slot.

2008-05-15      Joel Sherrill <joel.sherrill@OARcorp.com>

        * shared/bspstart.c, shared/start.S: 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.

2008-05-12      Joel Sherrill <joel.sherrill@OARcorp.com>

        * shared/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.

        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.

        be with or without DCache snooping. Caches without snooping needs the
        drivers to flush cache or use the sparc instruction lda to force
        cache miss...)

2007-09-05      Daniel Hellstrom <daniel@gaisler.com>

        * Makefile.am: LEON3 AMBA PnP bus scanning moved to shared/amba/amba.c
        and shared/include/ambapp.h. The AMBA scanning was improved to take
        account for PnP info address translation. This is useful when
        scanning remote AMBA busses for example when a board connected with
        PCI has an AMBA bus that needs to be scanned, before the addresses
        was hard coded. Also, LEON2 now have AMBA PnP bus scanning support.
        By using the new AMBA scanning routines it is possible to isolate the
        AMBA scanning code to ambapp.c, however existing drivers should be
        updated to use them in order to save space.

        * shared/bspstart.c, shared/start.S: Use common clock driver template
        and eliminate all fast idle code specific to this BSP. This
        eliminates a fair amount of code in the BSP clock driver and
        bsp_startup. The LEON3 has to do a scan of the AMBA bus to find the
        timer so I added the new hook Clock_driver_support_find_timer to
        support this. In general, there was some clean up to the file headers
        of various files.
