[ECOS] [PATCH] for ROMRAM support for PID board

Hi,
	Please find attached two files one containing a tgz file with the
three mlt files (new files) and a patch against CVS for the ROM/RAM pid
support 

I've fixed most of things requested by Jonathan, the only one remaining is
the 0x8000 define that I've called CYGHWR_HAL_RAM_VADDR, I cannot think
how to get this, for the UNMAPPED macro, it needs to come from a .h as
0x8000, I cannot use __exception_handlers and it seems to generate a
reset_vector address that is total crap, (it seems to use the variable
storing execption_handlers rather than the contents...

Maybe I'm still missing something but I think I messed around with this a
fair bit..

Also to use the ROMRAM image with the flash programmer for the PID board
the arm-elf-objcopy command is different than when doing a ROM image

arm-elf-objcopy --strip-debug --change-address=0x58000 <romram.in>
<flash.out>

The change addresses value is different.. this may require a note in the
PID docs..

Dave.
