support for CONFIG_SERIAL_TAG on ARM boards

Hi,

please consider this:

* Patch by Steven Scholz, 19 May 2005:
Add support for CONFIG_SERIAL_TAG on ARM baords

If someone wants to pass the board's serial number to the ARM linux kernel using the ATAG_SERIAL mechanism, all she has to do is

#define CONFIG_REVISION_TAG

in the board config file and implement a trivial, board specific

#ifdef CONFIG_SERIAL_TAG
void get_board_serial(struct tag_serialnr *serialnr)

{
	serialnr->low = (u32) sernum;
	serialnr->high= (u32) 0;
}

#endif

Same goes for CONFIG_REVISION_TAG.

Thanks a million!
