According to AHCI Spec 1.3 GHC.AE bit description:
"The implementation of this bit is dependent upon the value of the
CAP.SAM bit. If CAP.SAM is '0', then GHC.AE shall be read-write and shall
have a reset value of '0'. If CAP.SAM is '1', then AE shall be read-only
and shall have a reset value of '1'."
Being in AhciMode, for proper operation it is required, that GHC.AE bit
is always set, before any other AHCI registers are written to. Current
AhciMode implementation, both in AhciReset() and AhciModeInitialization()
functions, set GHC.AE bit only depending on 'CAP.SAM == 0' condition,
assuming (according to the AHCI spec), that otherwise it has to be set
anyway. It may however happen, that even if 'CAP.SAM == 1', GHC.AE
requires updating by software.
This patch enables in AhciMode setting GHC.AE in case its initial value
is '0'. It fixes AHCI support for Marvell Armada 70x0 and 80x0 SoC
families. The change is transparent to all other platforms.

If there is no multiplier, the DEV bit of the ATA device register would
always be set. It causes that some ATA hard drives don't response the
ATA identity command sent to them.
Below is the description about DEV bit in ATA spec:
A device is selected when the DEV bit of the Device register is equal to
the device number assigned to the device by means of a Device 0/Device 1
jumper or switch, or use of the CSEL signal.
Below is the description about DEV bit in SATA spec:
When the DEV bit in the Device register is set to one, selecting the
non-existent Device 1, the host adapter shall respond to register reads
and writes as specified for a Device 0 with no Device 1 present, as
defined in the ATA/ATAPI-5 standard.

For some SCSI commands, notably INQUIRY, it's relatively common for
the device to provide less data than we intended to read, and for
this reason EFI_EXT_SCSI_PASS_THRU_SCSI_REQUEST_PACKET makes
InTransferLength and OutTransferLength read-write. Make ATAPI
aware of this.
This makes it possible to handle EFI_NOT_READY always, not just
for read as done in r19685.
I've chosen to use a break statement instead of calling
CheckStatusRegister directly; the break statement reaches a
pre-existing call the CheckStatusRegister function. This
ensures that the assignment to *ByteCount is not missed, and
adds a further sanity check to DRQClear.

SVN r19611 (git commit 7cac240163), "MdeModulePkg/Ide: return correct
status when DRQ is not ready for ATAPI", changed the behavior of
AtaPacketReadWrite(), when DRQReady2() reported an error. The previous
logic had been to:
(a) terminate the transfer loop,
(b) check the status register with CheckStatusRegister(), and determine
AtaPacketReadWrite()'s return code directly from that.
Action (a) had been correct, but action (b) had masked genuine errors.
For example, when DRQReady2() reported EFI_TIMEOUT -- because the BSY bit
had not been cleared within the allotted time --, CheckStatusRegister()
would report EFI_SUCCESS, simply *because* BSY was still set, and the rest
of the status bits could not be evaluated.
SVN r19611 (git commit 7cac240163) intended to fix action (b) by directly
propagating the error code of DRQReady2() from AtaPacketReadWrite(),
eliminating the CheckStatusRegister() call. This was the right thing for
most of the errors reported by DRQReady2() -- timeout, command abort,
other device error --, but there was one exception: the "read" sub-case of
EFI_NOT_READY, which stands for "'read' complete, with less data available
than the requested amount".
Regarding the "write" sub-case of EFI_NOT_READY: the
AtaPacketCommandExecute() function programs the full transfer length into
the IDE device before it calls AtaPacketReadWrite(), and
AtaPacketReadWrite() only uses CylinderLsb and CylinderMsb for "chunking"
(as requested by the device). Therefore the device cannot justifiedly
clear DRQ earlier than seeing the entire data, when writing.
However, when reading from the device, a "short read" is a successful
operation. (The actual read length will be decoded by the higher level
protocols.) And "short reads" had been handled correctly by the logic
before git 7cac240163. Namely, when DRQReady2() returns EFI_NOT_READY, the
BSY bit is already clear, and we can call CheckStatusRegister() to
investigate all the other bits it cares about.
Therefore restore the logic from before git 7cac240163, but only for the
"read" sub-case of EFI_NOT_READY.
This problem was encountered with OVMF running on QEMU's i440fx IDE
emulation. Many thanks to John Snow for analyzing QEMU's behavior, and
pointing out that it adhered to the relevant specs.

The DRQReady() and DRQReady2() functions only differ in that they poll
different status registers for BSY, ERR, and DRQ: the former looks at the
Status Register (clearing interrupt status), while the latter looks at the
Alternate Status Register (not clearing interrupt status).
They both correctly return a unique status code, EFI_NOT_READY, for the
BSY==0 && ERR==0 && DRQ==0
case; that is, when the device reports "command complete".
However, the functions' leading comments don't explain this case, so it's
easy to miss in callers. Update the comments.

Some IDE controllers only update ID fields such as sector information on
specific commands such as the DIAG command.
The master/slave device is therefore selected both before and after
sending the DIAG command; otherwise reading the IDE registers yields the
master's ID fields.
(Reza's patch originally *moved* the master/slave selection from after the
DIAG command before it, however Feng asked for the original master/slave
select to be preserved; effectively making the master/slave select
*bracket* the DIAG command. See this subthread:

Setting a bit in the PxSACT register for a command in the command list indicates
to the controller that the command list slot contains a native queued command (NCQ).
This can cause problems with some controllers (one such controller is the Marvell 9128).
Since NCQ commands are not used, don't set the PxACT register for commands issued.
