[ECOS] PID ROM/RAM bootup support

Hi,
	Please find attached some PID ROM/RAM bootup code, 

the tgz contains the ROM/RAM mlt files (similiar to RAM files with some
ROM stuff added) I've no idea if these will auto-generate correctly, 

and a diff -u containing the changes to the hal I've made to support it, 
there is still one dodgy point in the diffs for UNMAPPED_PTR, I'm using a
define from hal_platform_setup.h PID_RAM_BASE=0x8000 to decide how much I
need to subtract for the write vector.. this doesn't seem the Right Way to
do things, but it is the only way I can get the correct address for the
reset vector..

This is due to RAM starting at 0 but the code starting at 0x8000,

This builds code that can boot on the PID ROM get copied to RAM and
execute..

Regards,
	Dave.
