- * If a Natoma chipset is present and this is a revision 1 zr36057,

- * (RJ: This statement is from Dave Perks' original driver,

- * RJ: The contents grab buffers needs never be accessed in the driver.
- * Therefore there is no need to allocate them with vmalloc in order
- * to get a contiguous virtual memory space.
- * I don't understand why many other drivers first allocate them with
- * vmalloc (which uses internally also get_zeroed_page, but delivers you
- * virtual addresses) and then again have to make a lot of efforts
- * to get the physical address.
- *
- * Ben Capper:
- * On big-endian architectures (such as ppc) some extra steps
- * are needed. When reading and writing to the stat_com array
- * and fragment buffers, the device expects to see little-
- * endian values. The use of cpu_to_le32() and le32_to_cpu()
- * in this function (and one or two others in zoran_device.c)
- * ensure that these values are always stored in little-endian
- * form, regardless of architecture. The zr36057 does Very Bad
- * Things on big endian architectures if the stat_com array
- * and fragment buffers are not little-endian.
