2009-05-08 Kate Feng <feng1@bnl.gov>

	* include/bsp.h, start/start.S, startup/bspstart.c:
	added CONFIGURE_MALLOC_BSP_SUPPORTS_SBRK in bsp.h.
	removed BSP_INIT_STACK_SIZE in bsp.h -- it uses __stack defined
	by the linker script (shared/startup/linkcmds) for the initial
	stack.
	replaced __rtems_end+4096 with __stack in start.S
	Removed legacy code in bspstart.c (inherited from old mvme2307 BSP
	but not relevant to this one) that tested trapping
	into PPCBug.
	Changed ConfVPD_buff[] to be static and added ReadConfVPD_buf() in
	bspstart.c
