AFAIK, writeX macros should swap as needed, i.e.

	writel(0x100,ioaddr);

should arrive as bit 8 set on the hardware. [please correct me if I'm 
wrong] Thus the input into write{b,w,l} should be in host byte order.

	u{8,16,32}	array[];

	__set_bit_{8,16,32}(,array);

	write{b,w,l}(array[],ioaddr);

would achieve that.
