306 | * each MJPEG buffer needs to be physically contiguous. | |

310 | * RJ: The contents grab buffers needs never be accessed in the driver. | |
311 | * Therefore there is no need to allocate them with vmalloc in order | |
312 | * to get a contiguous virtual memory space. | |
313 | * I don't understand why many other drivers first allocate them with | |
314 | * vmalloc (which uses internally also get_zeroed_page, but delivers you | |
315 | * virtual addresses) and then again have to make a lot of efforts | |
316 | * to get the physical address. | |
317 | * | |
318 | * Ben Capper: | |
319 | * On big-endian architectures (such as ppc) some extra steps | |
320 | * are needed. When reading and writing to the stat_com array | |
321 | * and fragment buffers, the device expects to see little- | |
322 | * endian values. The use of cpu_to_le32() and le32_to_cpu() | |
323 | * in this function (and one or two others in zoran_device.c) | |
324 | * ensure that these values are always stored in little-endian | |
325 | * form, regardless of architecture. The zr36057 does Very Bad | |
326 | * Things on big endian architectures if the stat_com array | |
