* 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.
*
* The chipsets all follow very much the same design. The orginal Triton
* series chipsets do _not_ support independant device timings, but this
* is fixed in Triton II. With the odd mobile exception the chips then
* change little except in gaining more modes until SATA arrives. This
* driver supports only the chips with independant timing (that is those
* with SITRE and the 0x44 timing register). See pata_oldpiix and pata_mpiix
* for the early chip drivers.
*
* 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
