pc: Make -no-fd-bootchk stick across boot order changes
Option -no-fd-bootchk asks the BIOS to attempt booting from a floppy
even when the boot sector signature isn't there, by setting a bit in
RTC CMOS. It was added back in 2006 (commit
52ca8d6a).
Two years later, commit
0ecdffbb added monitor command boot_set.
Implemented by new function pc_boot_set(). It unconditionally clears
the floppy signature bit in CMOS.
Commit
e0f084bf added -boot option once to automatically change the
boot order on first reset. Reuses pc_boot_set(), thus also clears the
floppy signature bit. Commit
d9346e81 took care to preserve this
behavior.
Thus, -no-fd-bootchk applies to any number of boots. Except it
applies just to the first boot with -boot once, and never after
boot_set. Weird. Make it stick instead: set the bit according to
-no-fd-bootchk in pc_boot_set().

vl: Fix -boot order and once regressions, and related bugs
Option "once" sets up a different boot order just for the initial
boot. Boot order reverts back to normal on reset. Option "order"
changes the normal boot order.
The reversal is implemented by reset handler restore_boot_devices(),
which takes the boot order to revert to as argument.
restore_boot_devices() does nothing on its first call, because that
must be the initial machine reset. On its second call, it changes the
boot order back, and unregisters itself.
Because we register the handler right when -boot gets parsed, we can
revert to an incorrect normal boot order, and multiple -boot can
interact in funny ways.
Here's how things work without -boot once or order:
* boot_devices is "".
* main() passes machine->boot_order to to machine->init(), because
boot_devices is "". machine->init() configures firmware
accordingly. For PC machines, machine->boot_order is "cad", and
pc_cmos_init() writes it to RTC CMOS, where SeaBIOS picks it up.
Now consider -boot order=:
* boot_devices is "".
* -boot order= sets boot_devices to "" (no change).
* main() passes machine->boot_order to to machine->init(), because
boot_devices is "", as above.
Bug: -boot order= has no effect. Broken in commit
e4ada29e.
Next, consider -boot once=a:
* boot_devices is "".
* -boot once=a registers restore_boot_devices() with argument "", and
sets boot_devices to "a".
* main() passes boot_devices "a" to machine->init(), which configures
firmware accordingly. For PC machines, pc_cmos_init() writes the
boot order to RTC CMOS.
* main() calls qemu_system_reset(). This runs reset handlers.
- restore_boot_devices() gets called with argument "". Does
nothing, because it's the first call.
* Machine boots, boot order is "a".
* Machine resets (e.g. monitor command). Reset handlers run.
- restore_boot_devices() gets called with argument "". Calls
qemu_boot_set("") to reconfigure firmware. For PC machines,
pc_boot_set() writes it into RTC CMOS. Reset handler
unregistered.
Bug: boot order reverts to "" instead of machine->boot_order. The
actual boot order depends on how firmware interprets "". Broken
in commit
e4ada29e.
Next, consider -boot once=a -boot order=c:
* boot_devices is "".
* -boot once=a registers restore_boot_devices() with argument "", and
sets boot_devices to "a".
* -boot order=c sets boot_devices to "c".
* main() passes boot_devices "c" to machine->init(), which configures
firmware accordingly. For PC machines, pc_cmos_init() writes the
boot order to RTC CMOS.
* main() calls qemu_system_reset(). This runs reset handlers.
- restore_boot_devices() gets called with argument "". Does
nothing, because it's the first call.
* Machine boots, boot order is "c".
Bug: it should be "a". I figure this has always been broken.
* Machine resets (e.g. monitor command). Reset handlers run.
- restore_boot_devices() gets called with argument "". Calls
qemu_boot_set("") to reconfigure firmware. For PC machines,
pc_boot_set() writes it into RTC CMOS. Reset handler

Bug: boot order reverts to "" instead of "c". I figure this has
always been broken, just differently broken before commit
e4ada29e.
Next, consider -boot once=a -boot once=b -boot once=c:

* -boot once=a registers restore_boot_devices() with argument "", and
sets boot_devices to "a".
* -boot once=b registers restore_boot_devices() with argument "a", and
sets boot_devices to "b".
* -boot once=c registers restore_boot_devices() with argument "b", and
sets boot_devices to "c".
* main() passes boot_devices "c" to machine->init(), which configures
firmware accordingly. For PC machines, pc_cmos_init() writes the
boot order to RTC CMOS.
* main() calls qemu_system_reset(). This runs reset handlers.
- restore_boot_devices() gets called with argument "". Does

- restore_boot_devices() gets called with argument "a". Calls

- restore_boot_devices() gets called with argument "b". Calls
qemu_boot_set("b") to reconfigure firmware. For PC machines,
pc_boot_set() writes it into RTC CMOS. Reset handler
unregistered.
* Machine boots, boot order is "b".
Bug: should really be "c", because that came last, and for all other
-boot options, the last one wins. I figure this was broken some
time before commit
37905d6a, and fixed there only for a single
occurence of "once".
* Machine resets (e.g. monitor command). Reset handlers run.
- restore_boot_devices() gets called with argument "". Calls
qemu_boot_set("") to reconfigure firmware. For PC machines,
pc_boot_set() writes it into RTC CMOS. Reset handler

Same bug as above: boot order reverts to "" instead of
machine->boot_order.
Fix by acting upon -boot options order, once and menu only after
option parsing is complete, and the machine is known. This is how the
other -boot options work already.

scsi-generic: fix sign extension of READ CAPACITY(10) data
Issuing the READ CAPACITY(10) command in the guest will cause QEMU
to update its knowledge of the maximum accessible LBA in the disk.
The recorded maximum LBA will be wrong if the disk is bigger than
1TB, because ldl_be_p returns a signed int.
When this is fixed, a latent bug will be unmasked. If the READ
CAPACITY(10) command reported an overflow (0xFFFFFFFF), we must
not overwrite the previously-known maximum accessible LBA, or the guest
will fail to access the disk above the first 2TB.

scsi: reset cdrom tray statuses on scsi_disk_reset
Tray statuses should be also reset. Some guests may lock the tray and
right after resetting the guest it should be unlocked and closed. This
is done on power-on, reset and resume from suspend/hibernate on bare-metal.
This fix is already committed for IDE CD.
Check the commit
a7f3d65b65b8c86a5ff0c0abcfefb45e2ec6fe4c.
Test results on bare-metal:
- on reset/power-on the CD-ROM tray is closed even before the monitor
is turned on
- on resume from suspend/hibernate the tray is also closed before
the monitor is turned on
From test results it seems that this behavior is OS and probably BIOS
independent.

ide-test: fix failure for test_flush
bd07684aacfb61668ae2c25b7dd00b64f3d7c7f3 added a test to ensure BSY
flag is set when a flush request is in flight. It does this by setting
a blkdebug breakpoint on flush_to_os before issuing a CMD_FLUSH_CACHE.
It then resumes CMD_FLUSH_CACHE operation and checks that BSY is unset.
The actual unsetting of BSY does not occur until ide_flush_cb gets
called in a bh, however, so in some cases this check will race with
the actual completion.
Fix this by polling the ide status register until BSY flag gets unset
before we do our final sanity checks. According to
f68ec8379e88502b4841a110c070e9b118d3151c this is in line with how a guest
would determine whether or not the device is still busy.

configure: Require libfdt for arm, ppc, microblaze softmmu targets
A number of our softmmu targets (PPC, ARM, Microblaze) now more or
less require flattened device tree support for various board models
to work correctly. Make libfdt mandatory if the target list includes
these, rather than building unhelpful half-functional binaries.

configure: dtc: Probe for libfdt_env.h
Currently QEMU provides a local clone of the file libfdt_env.h in
/include. This file is supposed to come with the libfdt package and is
only needed for broken installs of libfdt. Now that we have submodule
dtc, just ignore these broken installs and prompt for the dtc submodule
install instead. QEMU's local libfdt_env.h is removed accordingly.
Manifests as a bug when building QEMU with modern libfdt. The new
version of libfdt does not compile when QEMUs libfdt_env.h takes
precedence over the hosts.
