    hpt366: simplify UltraDMA filtering (take 4) · 2648e5d9
    Sergei Shtylyov authored
    Simplify UltraDMA mode filtering in the driver:
    - make use of the newly introduced 'udma_mask' field of 'ide_pci_device_t' to
      set the correct hwif->ultra_mask, modifying init_setup_hpt366() to select
      the correct mask based on the chip revision;
    - replace 'max_mode' field of the 'struct hpt_info' with 'max_ultra' specifying
      the maximum UltraDMA mode allowed;
    - rewrite hpt3xx_udma_filter() to differ the filters based on the 'chip_type'
      field, and only use it for HPT366 and HPT370[A] where it's really necessary.
