 * Documentation
 *      Publically available from Intel web site. Errata documentation
 * is also publically available. As an aide to anyone hacking on this
 * driver the list of errata that are relevant is below.going back to
 * PIIX4. Older device documentation is now a bit tricky to find.
 *
 * Errata of note:
 *
 * Unfixable
 *      PIIX4    errata #9      - Only on ultra obscure hw
 *      ICH3     errata #13     - Not observed to affect real hw
 *                                by Intel
 *
 * Things we must deal with
 *      PIIX4   errata #10      - BM IDE hang with non UDMA
 *                                (must stop/start dma to recover)
 *      440MX   errata #15      - As PIIX4 errata #10
 *      PIIX4   errata #15      - Must not read control registers
 *                                during a PIO transfer
 *      440MX   errata #13      - As PIIX4 errata #15
 *      ICH2    errata #21      - DMA mode 0 doesn't work right
 *      ICH0/1  errata #55      - As ICH2 errata #21
 *      ICH2    spec c #9       - Extra operations needed to handle
 *                                drive hotswap [NOT YET SUPPORTED]
 *      ICH2    spec c #20      - IDE PRD must not cross a 64K boundary
 *                                and must be dword aligned
 *      ICH2    spec c #24      - UDMA mode 4,5 t85/86 should be 6ns not 3.3
 *
 * Should have been BIOS fixed:
 *      450NX:  errata #19      - DMA hangs on old 450NX
 *      450NX:  errata #20      - DMA hangs on old 450NX
 *      450NX:  errata #25      - Corruption with DMA on old 450NX
 *      ICH3    errata #15      - IDE deadlock under high load
 *                                (BIOS must set dev 31 fn 0 bit 23)
 *      ICH3    errata #18      - Don't use native mode
