		FUNCTION inp, outp, inpw, outpw, inpdw, outpdw

		DESCRIPTION
		IN/OUT port macros for byte and word ports, typically inlined by compilers
		which support these routines

		PARAMETERS
		inp( xx_addr )
		inpw( xx_addr )
		inpdw( xx_addr )
		outp( xx_addr, xx_byte_val )
		outpw( xx_addr, xx_word_val )
		outpdw( xx_addr, xx_dword_val )
		xx_addr - Address of port to read or write (may be memory mapped)
		xx_byte_val - 8 bit value to write
		xx_word_val - 16 bit value to write
		xx_dword_val - 32 bit value to write

		DEPENDENCIES
		None

		RETURN VALUE
		inp/inpw/inpdw: the byte, word or dword read from the given address
		outp/outpw/outpdw: the byte, word or dword written to the given address

		SIDE EFFECTS
		None.
