284 * If a Natoma chipset is present and this is a revision 1 zr36057,
285 * each MJPEG buffer needs to be physically contiguous.
286 * (RJ: This statement is from Dave Perks' original driver,
287 * I could never check it because I have a zr36067)
289 * RJ: The contents grab buffers needs never be accessed in the driver.
290 * Therefore there is no need to allocate them with vmalloc in order
291 * to get a contiguous virtual memory space.
292 * I don't understand why many other drivers first allocate them with
293 * vmalloc (which uses internally also get_zeroed_page, but delivers you
294 * virtual addresses) and then again have to make a lot of efforts
295 * to get the physical address.
298 * On big-endian architectures (such as ppc) some extra steps
299 * are needed. When reading and writing to the stat_com array
300 * and fragment buffers, the device expects to see little-
301 * endian values. The use of cpu_to_le32() and le32_to_cpu()
302 * in this function (and one or two others in zoran_device.c)
303 * ensure that these values are always stored in little-endian
304 * form, regardless of architecture. The zr36057 does Very Bad
305 * Things on big endian architectures if the stat_com array
306 * and fragment buffers are not little-endian.
