Re: [PATCH] pm8001: support HDA (flashless) mode

[Mark Salyzyn <mark_salyzyn@xyratex.com>]

PMC still does not like the images or firmware header files getting out willy-nilly, have not got free redistribution rights or approvals (in effect, as their agent). And they won't take the action to submit them to the Linux archives. As an OEM customer we are bound to follow their NDA requirements and approvals. Someone not bound by the NDA, on the other hand, can do so <hint hint>.

Conversion from their header format to binary is as follows:

	for i in aap1img.h ilaimg.h iopimg.h istrimg.h ; do
		gcc -x c -c -o ${i%.h}.bin ${i}
		objcopy -O binary ${i%h}.bin
	done

Sincerely -- Mark Salyzyn
