To start a new port to a new hardware platform, copy these files and implement
the required documented content.

You can also start from a similar already ported platform accessible on the CVS
tree.

special note on HAL initialisation
----------------------------------

startup.c or startup.asm is the main RESET entry point. This file must be placed
in the proto/cos/<platform> sub-folder.

__hal_init() function in halinit.c file is the main HAL entry point for
initialization. This file must be placed in the proto/hal/<platform>
sub-folder.

The initialisation is a 4 parts process :

. startup at the RESET vector. Initialize (typically in assembler except for
  the simulator) a lot of low-level stuff such as :
	. encipher memory data
	. erase memory data
	. auto-detect kind of reset (warm/cold) and update *rr_raison*
	. setup a stack !

. then auto-detect the communication interface in use, updating *if_type*

. then call cos_init() function (which will indirectly call __hal_init())

. finally call the __bios_tcl_main() function to enter T=CL FSM or the
  cos_main() function for the command dispatcher, based on the current
  communication interface in use.
