b3141c0625 sdcard: Use the ldst API
The load/store API will ease further code movement.

Per the Physical Layer Simplified Spec. "3.6 Bus Protocol":

  "In the CMD line the Most Significant Bit (MSB) is transmitted
   first, the Least Significant Bit (LSB) is the last."

13606b9951 sd: Don't trace SDRequest crc field
We don't actually implement SD command CRC checking, because
for almost all of our SD controllers the CRC generation is
done in hardware, and so modelling CRC generation and checking
would be a bit pointless. (The exception is that milkymist-memcard
makes the guest software compute the CRC.)

As a result almost all of our SD controller models don't bother
to set the SDRequest crc field, and the SD card model doesn't
check it. So the tracing of it in sdbus_do_command() provokes
Coverity warnings about use of uninitialized data.

Drop the CRC field from the trace; we can always add it back
if and when we do anything useful with the CRC.

Fixes Coverity issues 1386072, 1386074, 1386076, 1390571.

dcfebcf9a3 sdcard: Reduce sdcard_set_blocklen() trace digits
Per the Physical Layer Simplified Spec. "5.3 CSD Register":

  "The maximum block length might therefore be in the range 512...2048 bytes"

Therefore 3 hexdigits are enough to report the block length.

d1b322182b sdcard: Disable SEND_IF_COND (CMD8) for Spec v1
CMD8 is "Reserved" in Spec v1.10.

Spec v2.00 introduces the SEND_IF_COND command:

  6.4.1 Power Up

    CMD8 is newly added in the Physical Layer Specification Version
    2.00 to support multiple voltage ranges and used to check whether
    the card supports supplied voltage. The version 2.00 or later host
    shall issue CMD8 and verify voltage before card initialization.
    The host that does not support CMD8 shall supply high voltage range.

9e1245795f sdcard: Update the Configuration Register (SCR) to Spec Version 1.10
The initial implementation is based on the Specs v1.10 (see a1bb27b1e9).

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, a1bb27b1e9.

The 25MB/sec High-Speed mode was already updated in d7ecb86752.

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."

f6fb1f9b31 sdcard: Correct CRC16 offset in sd_function_switch()
Per the Physical Layer Simplified Spec. "4.3.10.4 Switch Function Status":

  The block length is predefined to 512 bits

and "4.10.2 SD Status":

  The SD Status contains status bits that are related to the SD Memory Card
  proprietary features and may be used for future application-specific usage.
  The size of the SD Status is one data block of 512 bit. The content of this
  register is transmitted to the Host over the DAT bus along with a 16-bit CRC.

Thus the 16-bit CRC goes at offset 64.

f3d9fe8f95 hw/sd/bcm2835_sdhost: Don't raise spurious interrupts
The Linux bcm2835_sdhost driver doesn't work on QEMU, because our
model raises spurious data interrupts.  Our function
bcm2835_sdhost_fifo_run() will flag an interrupt any time it is
called with s->datacnt == 0, even if the host hasn't actually issued
a data read or write command yet.  This means that the driver gets a
spurious data interrupt as soon as it enables IRQs and then does
something else that causes us to call the fifo_run routine, like
writing to SDHCFG, and before it does the write to SDCMD to issue the
read.  The driver's IRQ handler then spins forever complaining that
there's no data and the SD controller isn't in a state where there's
going to be any data:

[   41.040738] sdhost-bcm2835 3f202000.mmc: fsm 1, hsts 00000000
[   41.042059] sdhost-bcm2835 3f202000.mmc: fsm 1, hsts 00000000
(continues forever).

Move the interrupt flag setting to more plausible places:
 * for BUSY, raise this as soon as a BUSYWAIT command has executed
 * for DATA, raise this when the FIFO has any space free (for a write)
   or any data in it (for a read)
 * for BLOCK, raise this when the data count is 0 and we've
   actually done some reading or writing

This is pure guesswork since the documentation for this hardware is
not public, but it is sufficient to get the Linux bcm2835_sdhost
driver to work.

Since omap_mmc is still using the legacy SD card API, the SD
card created by sd_init() is not plugged into any bus. This
means that the controller has to reset it manually.

Failing to do this mostly didn't affect the guest since the
guest typically does a programmed SD card reset as part of
its SD controller driver initialization, but would mean that
migration fails because it's only in sd_reset() that we
set up the wpgrps_size field.

fd3b02c889 pci: Add INTERFACE_CONVENTIONAL_PCI_DEVICE to Conventional PCI devices
Add INTERFACE_CONVENTIONAL_PCI_DEVICE to all direct subtypes of
TYPE_PCI_DEVICE, except:

1) The ones that already have INTERFACE_PCIE_DEVICE set:

* base-xhci
* e1000e
* nvme
* pvscsi
* vfio-pci
* virtio-pci
* vmxnet3

2) base-pci-bridge

Not all PCI bridges are Conventional PCI devices, so
INTERFACE_CONVENTIONAL_PCI_DEVICE is added only to the subtypes
that are actually Conventional PCI:

* dec-21154-p2p-bridge
* i82801b11-bridge
* pbm-bridge
* pci-bridge

The direct subtypes of base-pci-bridge not touched by this patch
are:

* xilinx-pcie-root: Already marked as PCIe-only.
* pcie-pci-bridge: Already marked as PCIe-only.
* pcie-port: all non-abstract subtypes of pcie-port are already
  marked as PCIe-only devices.

3) megasas-base

Not all megasas devices are Conventional PCI devices, so the
interface names are added to the subclasses registered by
megasas_register_types(), according to information in the
megasas_devices[] array.

"megasas-gen2" already implements INTERFACE_PCIE_DEVICE, so add
INTERFACE_CONVENTIONAL_PCI_DEVICE only to "megasas".

e4f4fb1eca sysbus: Set user_creatable=false by default on TYPE_SYS_BUS_DEVICE
commit 33cd52b5d7 unset
cannot_instantiate_with_device_add_yet in TYPE_SYSBUS, making all
sysbus devices appear on "-device help" and lack the "no-user"
flag in "info qdm".

To fix this, we can set user_creatable=false by default on
TYPE_SYS_BUS_DEVICE, but this requires setting
user_creatable=true explicitly on the sysbus devices that
actually work with -device.

Fortunately today we have just a few has_dynamic_sysbus=1
machines: virt, pc-q35-*, ppce500, and spapr.

virt, ppce500, and spapr have extra checks to ensure just a few
device types can be instantiated:

* virt supports only TYPE_VFIO_CALXEDA_XGMAC, TYPE_VFIO_AMD_XGBE.
* ppce500 supports only TYPE_ETSEC_COMMON.
* spapr supports only TYPE_SPAPR_PCI_HOST_BRIDGE.

This patch sets user_creatable=true explicitly on those 4 device
classes.

Now, the more complex cases:

pc-q35-*: q35 has no sysbus device whitelist yet (which is a
separate bug). We are in the process of fixing it and building a
sysbus whitelist on q35, but in the meantime we can fix the
"-device help" and "info qdm" bugs mentioned above. Also, despite
not being strictly necessary for fixing the q35 bug, reducing the
list of user_creatable=true devices will help us be more
confident when building the q35 whitelist.

xen: We also have a hack at xen_set_dynamic_sysbus(), that sets
has_dynamic_sysbus=true at runtime when using the Xen
accelerator. This hack is only used to allow xen-backend devices
to be dynamically plugged/unplugged.

This means today we can use -device with the following 22 device
types, that are the ones compiled into the qemu-system-x86_64 and
qemu-system-i386 binaries:

* allwinner-ahci
* amd-iommu
* cfi.pflash01
* esp
* fw_cfg_io
* fw_cfg_mem
* generic-sdhci
* hpet
* intel-iommu
* ioapic
* isabus-bridge
* kvmclock
* kvm-ioapic
* kvmvapic
* SUNW,fdtwo
* sysbus-ahci
* sysbus-fdc
* sysbus-ohci
* unimplemented-device
* virtio-mmio
* xen-backend
* xen-sysdev

This patch adds user_creatable=true explicitly to those devices,
temporarily, just to keep 100% compatibility with existing
behavior of q35. Subsequent patches will remove
user_creatable=true from the devices that are really not meant to
user-creatable on any machine, and remove the FIXME comment from
the ones that are really supposed to be user-creatable. This is
being done in separate patches because we still don't have an
obvious list of devices that will be whitelisted by q35, and I
would like to get each device reviewed individually.

e90f2a8c3e qdev: Replace cannot_instantiate_with_device_add_yet with !user_creatable
cannot_instantiate_with_device_add_yet was introduced by commit
efec3dd631 to replace no_user. It was
supposed to be a temporary measure.

When it was introduced, we had 54
cannot_instantiate_with_device_add_yet=true lines in the code.
Today (3 years later) this number has not shrunk: we now have
57 cannot_instantiate_with_device_add_yet=true lines. I think it
is safe to say it is not a temporary measure, and we won't see
the flag go away soon.

Instead of a long field name that misleads people to believe it
is temporary, replace it a shorter and less misleading field:
user_creatable.

Except for code comments, changes were generated using the
following Coccinelle patch:

  expression DC;
  @@
  (
  -DC->cannot_instantiate_with_device_add_yet = false;
  +DC->user_creatable = true;
