0430891ce1 hw: Clean up includes
Clean up includes so that osdep.h is included first and headers
which it implies are not included manually.

This commit was created with scripts/clean-includes.

ba306c7a55 sd: Mark brittle abuse of blk_attach_dev() FIXME
blk_attach_dev() fails here only when we're working for device
"sdhci-pci" (which already attached the backend), and then we don't
want to attach a second time.  If we ever create another failure mode,
we're setting up ourselves to using the same backend from multiple
frontends, which is likely to end in tears.  Can't clean this up this
close to the release, so mark it FIXME.

5ec911c30f sdhci: Pass drive parameter to sdhci-pci via qdev property
Commit 19109131 disabled the sdhci-pci support because it used
drive_get_next().  This patch reenables sdhci-pci and changes it to
pass the drive via a qdev property - for example:
 -device sdhci-pci,drive=drive0 -drive id=drive0,if=sd,file=myimage

ef1e1e0782 maint: avoid useless "if (foo) free(foo)" pattern
The free() and g_free() functions both happily accept
NULL on any platform QEMU builds on. As such putting a
conditional 'if (foo)' check before calls to 'free(foo)'
merely serves to bloat the lines of code.

16b781aaef hw/sd: Don't pass BlockBackend to sd_reset()
The only valid BlockBackend to pass to sd_reset() is the one for
the SD card, which is sd->blk. Drop the second argument from this
function in favour of having it just use sd->blk.

c9d9331851 sd: convert sd_normal_command() ffs(3) call to ctz32()
ffs() cannot be replaced with ctz32() when the argument might be zero,
because ffs(0) returns 0 while ctz32(0) returns 32.

The ffs(3) call in sd_normal_command() is a special case though.  It can
be converted to ctz32() + 1 because the argument is never zero:

  if (!(req.arg >> 8) || (req.arg >> (ctz32(req.arg & ~0xff) + 1))) {
      ~~~~~~~~~~~~~~~
            ^--------------- req.arg cannot be zero

4be746345f hw: Convert from BlockDriverState to BlockBackend, mostly
Device models should access their block backends only through the
block-backend.h API.  Convert them, and drop direct includes of
inappropriate headers.

Just four uses of BlockDriverState are left:

* The Xen paravirtual block device backend (xen_disk.c) opens images
  itself when set up via xenbus, bypassing blockdev.c.  I figure it
  should go through qmp_blockdev_add() instead.

* Device model "usb-storage" prompts for keys.  No other device model
  does, and this one probably shouldn't do it, either.

* ide_issue_trim_cb() uses bdrv_aio_discard() instead of
  blk_aio_discard() because it fishes its backend out of a BlockAIOCB,
  which has only the BlockDriverState.

* PC87312State has an unused BlockDriverState[] member.

The next two commits take care of the latter two.

7179585688 hw/sd/sd.c: Drop unused sd_acmd_type[] array
Drop the sd_acmd_type[] array: it is never used. (The equivalent
sd_cmd_type[] array for normal commands is used to identify
those commands whose argument includes the card address in the
top 16 bits; but for app commands the card address is passed
with the APP_CMD prefix, not with the argument to the app command
itself.)

794cbc26eb sd: Avoid access to NULL BlockDriverState
Commit 4f8a066b5f (blockdev: Remove IF_*
check for read-only blockdev_init) added a usage of bdrv_is_read_only()
to sd_init(), which is called for versatilepb, versatileab and
xilinx-zynq-a9 machines among others with NULL argument by default,
causing the new qom-test to fail.

Add a check to prevent this.

4f8a066b5f blockdev: Remove IF_* check for read-only blockdev_init
IF_NONE allows read-only, which makes forbidding it in this place
for other types pretty much pointless.

Instead, make sure that all devices for which the check would have
errored out check in their init function that they don't get a read-only
BlockDriverState. This catches even cases where IF_NONE and -device is
used.

37ab4a5668 sd/sd.c: Fix "inquiry" ACMD41
QEMU models two (of the three) ACMD41 has two modes, "inquiry" and
"first". The selection logic for which of the two is incorrect - it
compares != 0 for the entire argument value rather than only bits 23:0
as per the spec. Fix.
