qemu-img: Recognize no creation support in -o help
The only users of print_block_option_help() are qemu-img create and
qemu-img convert for the output image, so this function is always used
for image creation (it used to be used for amendment also, but that is
no longer the case).
So if image creation is not supported by either the format or the
protocol, there is no need to print any option description, because the
user cannot create an image like this anyway.

qemu-img: Add print_amend_option_help()
The more generic print_block_option_help() function is not really
suitable for qemu-img amend, for a couple of reasons:
(1) We do not need to append the protocol-level options, as amendment
happens only on one node and does not descend downwards to its
children.
(2) print_block_option_help() says those options are "supported". For
option amendment, we do not really know that. So this new function
explicitly says that those options are the creation options, and not
all of them may be supported.
(3) If the driver does not support option amendment, we should not print
anything (except for an error message that amendment is not
supported).

qemu-img: Amendment support implies create_opts
Instead of checking whether a driver has a non-NULL create_opts we
should check whether it supports image amendment in the first place. If
it does, it must have create_opts.
On the other hand, if it does not have create_opts (so it does not
support amendment either), the error message "does not support any
options" is a bit useless. Stating clearly that the driver has no
amendment support whatsoever is probably better.

ahci: move PIO Setup FIS before transfer, fix it for ATAPI commands
The PIO Setup FIS is written in the PIO:Entry state, which comes before
the ATA and ATAPI data transfer states. As a result, the PIO Setup FIS
interrupt is now raised before DMA ends for ATAPI commands, and tests have
to be adjusted.
This is also hinted by the description of the command header in the AHCI
specification, where the "A" bit is described as
When ‘1’, indicates that a PIO setup FIS shall be sent by the device
indicating a transfer for the ATAPI command.
and also by the description of the ACMD (ATAPI command region):
The ATAPI command must be either 12 or 16 bytes in length. The length
transmitted by the HBA is determined by the PIO setup FIS that is sent
by the device requesting the ATAPI command.
QEMU, which conflates the "generator" and the "receiver" of the FIS into
one device, always uses ATAPI_PACKET_SIZE, aka 12, for the length.

ahci: fix PxCI register race
Fixes: https://bugs.launchpad.net/qemu/+bug/1769189
AHCI presently signals completion prior to the PxCI register being
cleared to indicate completion. If a guest driver attempts to issue
a new command in its IRQ handler, it might be surprised to learn there
is still a command pending.
In the case of Windows 10's boot driver, it will actually poll the IRQ
register hoping to find out when the command is done running -- which
will never happen, as there isn't a command running.
Fix this: clear PxCI in ahci_cmd_done and not in the asynchronous BH.
Because it now runs synchronously, we don't need to check if the command
is actually done by spying on the ATA registers. We know it's done.

sdcard: Update the Configuration Register (SCR) to Spec Version 1.10
The initial implementation is based on the Specs v1.10 (see a1bb27b1e98).
However the SCR is anouncing the card being v1.01.
The new chapters added in version 1.10 are:
4.3.10 Switch function command
Switch function command (CMD6) 1 is used to switch or expand
memory card functions. [...]
This is a new feature, introduced in SD physical Layer
Specification Version 1.10. Therefore, cards that are
compatible with earlier versions of the spec do not support
it. The host shall check the "SD_SPEC" field in the SCR
register to recognize what version of the spec the card
complies with before using CMD6. It is mandatory for SD
memory card of Ver1.10 to support CMD6.
4.3.11 High-Speed mode (25MB/sec interface speed)
Though the Rev 1.01 SD memory card supports up to 12.5MB/sec
interface speed, the speed of 25MB/sec is necessary to support
increasing performance needs of the host and because of memory
size which continues to grow.
To achieve 25MB/sec interface speed, clock rate is increased to
50MHz and CLK/CMD/DAT signal timing and circuit conditions are
reconsidered and changed from Physical Layer Specification
Version 1.01.
4.3.12 Command system (This chapter is newly added in version 1.10)
SD commands CMD34-37, CMD50, CMD57 are reserved for SD command
system expansion via the switch command.
[These commands] will be considered as illegal commands (as
defined in revision 1.01 of the SD physical layer specification).
The SWITCH_FUNCTION is implemented since the first commit, a1bb27b1e98.
The 25MB/sec High-Speed mode was already updated in d7ecb867529.
The current implementation does not implements CMD34-37, CMD50 and
CMD57, thus these commands already return ILLEGAL.
With this patch, the SCR register now matches the description of the header:
* SD Memory Card emulation as defined in the "SD Memory Card Physical
* layer specification, Version 1.10."
