Commit 0b183fc871:"memory: move mem_path handling to
memory_region_allocate_system_memory" split memory_region_init_ram and
memory_region_init_ram_from_file. Also it moved mem-path handling a step
up from memory_region_init_ram to memory_region_allocate_system_memory.
Therefore for any board that uses memory_region_init_ram directly,
-mem-path is not supported.
Fix this by replacing memory_region_init_ram with
memory_region_allocate_system_memory.

Device models aren't supposed to go on fishing expeditions for
backends. They should expose suitable properties for the user to set.
For onboard devices, board code sets them.
A number of sysbus devices pick up block backends in their init() /
instance_init() methods with drive_get_next() instead: sl-nand,
milkymist-memcard, pl181, generic-sdhci.
Likewise, a number of sysbus devices pick up character backends in
their init() / realize() methods with qemu_char_get_next_serial():
cadence_uart, digic-uart, etraxfs,serial, lm32-juart, lm32-uart,
milkymist-uart, pl011, stm32f2xx-usart, xlnx.xps-uartlite.
All these mistakes are already marked FIXME. See the commit that
added these FIXMEs for a more detailed explanation of what's wrong.
Fortunately, only machines ppce500 and pseries-* support -device with
sysbus devices, and none of the devices above is supported with these
machines.
Set cannot_instantiate_with_device_add_yet to preserve our luck.

NICs defined with -net nic are for board initialization to wire up.
Board code examines nd_table[] to find them, and creates devices with
their qdev NIC properties set accordingly.
Except "allwinner-a10" goes on a fishing expedition for NIC
configuration instead of exposing the usual NIC properties for board
code to set: it uses nd_table[0] in its instance_init() method.
Picking up the first -net nic option's configuration that way works
when the device is created by board code. But it's inappropriate for
-device and device_add. Not only is it inconsistent with how the
other block device models work (they get their configuration from
properties "mac", "vlan", "netdev"), it breaks when nd_table[0] has
been picked up by the board or a previous -device / device_add
already.
Example:
$ qemu-system-arm -S -M cubieboard -device allwinner-a10
qemu-system-arm: -device allwinner-a10: Property 'allwinner-emac.netdev' can't take value 'hub0port0', it's in use
Aborted (core dumped)
It also breaks in other entertaining ways:
$ qemu-system-arm -M highbank -device allwinner-a10
qemu-system-arm: -device allwinner-a10: Unsupported NIC model: xgmac
$ qemu-system-arm -M highbank -net nic,model=allwinner-emac -device allwinner-a10

Character devices defined with -serial and -parallel are for board

Except a few devices go on a fishing expedition for a suitable backend

Picking up backends that way works when the devices are created by

For instance, this invocation of qemu
qemu-system-aarch64 -M virt -cpu cortex-a57,aarch64=off -smp 2
produces the following error
qemu-system-aarch64: Expected key=value format, found aarch64

Three kinds of callers:
1. On failure, report the error and abort
Passing &error_abort does the job. No functional change.
2. On failure, report the error and exit()
This is qdev_prop_set_drive_nofail(). Error reporting moves from
qdev_prop_set_drive() to its caller. Because hiding away the error
in the monitor right before exit() isn't helpful, replace
qerror_report_err() by error_report_err(). Shouldn't make a
difference, because qdev_prop_set_drive_nofail() should never be
used in QMP context.
3. On failure, report the error and recover
This is usb_msd_init() and scsi_bus_legacy_add_drive(). Error
reporting and freeing the error object moves from
qdev_prop_set_drive() to its callers.
Because usb_msd_init() can't run in QMP context, replace
qerror_report_err() by error_report_err() there.
No functional change.
scsi_bus_legacy_add_drive() calling qerror_report_err() is of
course inappropriate, but this commit merely makes it more obvious.
The next one will clean it up.

Introduce the new boolean field "arm_boot_info.firmware_loaded". When this
field is set, it means that the portion of guest DRAM that the VCPU
normally starts to execute, or the pflash chip that the VCPU normally
starts to execute, has been populated by board-specific code with
full-fledged guest firmware code, before the board calls
arm_load_kernel().
Simultaneously, "arm_boot_info.firmware_loaded" guarantees that the board
code has set up the global firmware config instance, for arm_load_kernel()
to find with fw_cfg_find().
Guest kernel (-kernel) and guest firmware (-bios, -pflash) has always been
possible to specify independently on the command line. The following cases
should be considered:
nr -bios -pflash -kernel description
unit#0
-- ------- ------- ------- -------------------------------------------
1 present present absent Board code rejects this case, -bios and
present present present -pflash unit#0 are exclusive. Left intact
by this patch.
2 absent absent present Traditional kernel loading, with qemu's
minimal board firmware. Left intact by this
patch.
3 absent present absent Preexistent case for booting guest firmware
present absent absent loaded with -bios or -pflash. Left intact
by this patch.
4 absent absent absent Preexistent case for not loading any
firmware or kernel up-front. Left intact by
this patch.
5 present absent present New case introduced by this patch: kernel
absent present present image is passed to externally loaded
firmware in unmodified form, using fw_cfg.
An easy way to see that this patch doesn't interfere with existing cases
is to realize that "info->firmware_loaded" is constant zero at this point.
Which makes the "outer" condition unchanged, and the "inner" condition
(with the fw_cfg-related code) dead.

fw_cfg already supports exposure over MMIO (used in ppc/mac_newworld.c,
ppc/mac_oldworld.c, sparc/sun4m.c); we can easily add it to the "virt"
board.
Because MMIO access is slow on ARM KVM, we enable the guest, with
fw_cfg_init_mem_wide(), to transfer up to 8 bytes with a single access.
This has been measured to speed up transfers up to 7.5-fold, relative to
single byte data access, on both ARM KVM and x86_64 TCG.
The MMIO register block of fw_cfg is advertized in the device tree. As
base address we pick 0x09020000, which conforms to the comment preceding
"a15memmap": it falls in the miscellaneous device I/O range 128MB..256MB,
and it is aligned at 64KB. The DTB properties follow the documentation in
the Linux source file "Documentation/devicetree/bindings/arm/fw-cfg.txt".
fw_cfg automatically exports a number of files to the guest; for example,
"bootorder" (see fw_cfg_machine_reset()).

Add "secure" Vexpress machine specific property to allow override of the
default secure state configuration. By default, when using the QEMU
-kernel command line argument, Vexpress machines boot into NS/SVC. When using
the QEMU -bios command line argument, Vexpress machines boot into S/SVC.
The secure state can be changed from the default specifying the secure
state as a machine property. For example, the below command line would disable
security extensions on a -kernel Linux boot:
aarch64-softmmu/qemu-system-aarch64
-machine type=vexpress-a15,secure=off
-kernel ...

Add Vexpress machine objects for the the Cortex A9 & A15 variants. The older
style QEMUMachine types were replaced with dedicated TypeInfo objects. The new
objects include dedicated class init functions that currently ustilze dedicated
machine init methods. The previous qemu_register_machine calls were replaced
with the newer type_register_status calls.

Adds base Vexpress class and machine objects and infrastructure. This is in
preparation for switching to the full QEMU object model. The base vexpress
infrastructure is intended to handle common vexpress details.

Coverity reports the 'size' may be used uninitialized, but that can't happen,
because the caller has checked "if (binfo->dtb_filename || binfo->get_dtb)"
before call 'load_dtb'.
Here we simply remove the 'if (binfo->get_dtb)' to satisfy coverity.

Variable 'ram_lo' is allocated unconditionally, but used only in some cases.
When it is unused pointer will be lost at function exit, resulting in a
memory leak. Allocate memory for 'ram_lo' only if it is needed.
