The TEST UNIT READY, INQUIRY, MODE SENSE, REQUEST SENSE and READ CAPACITY
commands define bits [7:5] of Cdb[1] as Reserved (potentially as part of a
larger Reserved bitfield):
Command Reserved bitfield in Cdb[1] SCSI spec reference
------------------ --------------------------- -------------------
TEST UNIT READY all bits SPC-4 6.37
INQUIRY bits [7:2] SPC-4 6.4.1
MODE SENSE (6) bits [7:4] SPC-4 6.11.1
MODE SENSE (10) bits [7:5] SPC-4 6.12
REQUEST SENSE bits [7:1] SPC-4 6.29
READ CAPACITY (10) bits [7:1] SBC-3 5.16
READ CAPACITY (16) bits [7:5] SBC-3 5.17
Update the UefiScsiLib functions accordingly.
(In ScsiReadCapacity16Command() the LUN has not been encoded, so there we
just remove the useless ScsiIo->GetDeviceLocation() call, with its
auxiliary local variables.)
The EFI_SCSI_TARGET_MAX_BYTES and EFI_SCSI_LOGICAL_UNIT_NUMBER_MASK macros
become unused with this patch, remove them too.
