* sim.h: These changes enable RTEMS to automatically generate the ram_init file used by gdb with the BDM patches. The 332 has on-board chip select lines (for RAM and FLASH) that must be configured before use of these peripherals. These patches parse data from start.c where the chip select lines are configured in the runtime executable and automatically generates the gdb initialization file using the same settings. A great time saver. A similar file, ram_init_FW (flash writable), is also generated that the flash programming tool uses. * BSP/start/start.c: Must be modified to support above. * BSP/start/ram_init.ld, BSP/start/ram_init.sed: New files.
