| 439 | * |
| 440 | * If a Natoma chipset is present and this is a revision 1 zr36057, |

| 442 | * (RJ: This statement is from Dave Perks' original driver, |
| 443 | * I could never check it because I have a zr36067) |
| 444 | * The driver cares about this because it reduces the buffer |
| 445 | * size to MAX_KMALLOC_MEM in that case (which forces contiguous allocation). |
| 446 | * |
| 447 | * RJ: The contents grab buffers needs never be accessed in the driver. |
| 448 | * Therefore there is no need to allocate them with vmalloc in order |
| 449 | * to get a contiguous virtual memory space. |
| 450 | * I don't understand why many other drivers first allocate them with |
| 451 | * vmalloc (which uses internally also get_zeroed_page, but delivers you |
| 452 | * virtual addresses) and then again have to make a lot of efforts |
| 453 | * to get the physical address. |
| 454 | * |
| 455 | * Ben Capper: |
| 456 | * On big-endian architectures (such as ppc) some extra steps |
| 457 | * are needed. When reading and writing to the stat_com array |
| 458 | * and fragment buffers, the device expects to see little- |
| 459 | * endian values. The use of cpu_to_le32() and le32_to_cpu() |
| 460 | * in this function (and one or two others in zoran_device.c) |
| 461 | * ensure that these values are always stored in little-endian |
| 462 | * form, regardless of architecture. The zr36057 does Very Bad |
| 463 | * Things on big endian architectures if the stat_com array |
| 464 | * and fragment buffers are not little-endian. |
