- 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.
