* 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.
* 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.
* start.S: Modificatins to preserve the current CWP and adjust the
WIM accordingly. This improves compatibility with the remote
debugger and the mkprom prom-builder.
* ChangeLog, .cvsignore, Makefile.am, bspclean.c, bspstart.c,
gnatcommon.c, start.S: New files. Largely moved from ERC32
BSP to be able to be shared with LEON and other SPARC BSPs.
