[SeaBIOS] [PATCH 00/17] Block driver command dispatch cleanup

[Kevin O'Connor]

This series implements some code reorganization in an attempt to
simplify the disk driver command dispatch system.  The series should
have no user-visible changes - it's mostly just code reorg.

At the end of the series, the command dispatch for "scsi style"
devices is removed in favor of a single dispatch system for all
drives.

The series also makes the supported runtime modes (ie, 32bit or 16bit)
of drivers more explicit.

Kevin O'Connor (17):
  block: Split process_op() command dispatch up into multiple functions
  block: Introduce default_process_op() with common command handling
    codes
  block: Route scsi style commands through 'struct disk_op_s'
  blockcmd: Introduce scsi_fill_cmd()
  ata: Handle ATA ATAPI drives directly via 'struct disk_op_s' requests
  ahci: Handle AHCI ATAPI drives directly via 'struct disk_op_s'
    requests
  usb-msc: Handle USB drives directly via 'struct disk_op_s' requests
  usb-uas: Handle USB drives directly via 'struct disk_op_s' requests
  lsi-scsi: Handle LSI drives directly via 'struct disk_op_s' requests
  esp-scsi: Handle ESP drives directly via 'struct disk_op_s' requests
  megasas: Handle Megasas drives directly via 'struct disk_op_s'
    requests
  virtio-scsi: Handle virtio drives directly via 'struct disk_op_s'
    requests
  pvscsi: Move pvscsi_fill_req() code into pvscsi_cmd()
  pvscsi: Handle pvscsi drives directly via 'struct disk_op_s' requests
  blockcmd: Remove unused scsi_process_op() and cdb_cmd_data()
  blockcmd: Convert cdb_is_read() to scsi_is_read()
  block: Rename process_XXX_op() functions to XXX_process_op()
