Grant Grundler b312c33e36 [PARISC] Document that we tolerate "Relaxed Ordering" This means "DMA Read returns" can bypass "MMIO Writes". Violating the PCI specs in this case improves outbound DMA "flows" and is currently not required by any drivers. This is NOT a new behavior. Previous chipsets did this already and I believe ZX1 PDC was already setting this for hpux. I just want to further document the behavior.

/*
** HP VISUALIZE Workstation PCI Bus Defect
**
** "HP has discovered a potential system defect that can affect
** the behavior of five models of HP VISUALIZE workstations when
** equipped with third-party or customer-installed PCI I/O expansion
** cards. The defect is limited to the HP C180, C160, C160L, B160L,
** and B132L VISUALIZE workstations, and will only be encountered
** when data is transmitted through PCI I/O expansion cards on the
** PCI bus. HP-supplied graphics cards that utilize the PCI bus are
** not affected."

** REVISIT: "go/pci_defect" link below is stale.
