qdev_prop_set_drive() can fail. None of the other qdev_prop_set_FOO()
can; they abort on error.
To clean up this inconsistency, rename qdev_prop_set_drive() to
qdev_prop_set_drive_err(), and create a qdev_prop_set_drive() that
aborts on error.

qdev_prop_set_chr() screws up when the property already has a non-null
value: it neglects to release the old value. Both the old and the new
backend become attached to the same device. Unlike for block devices
(see previous commit), this can't be observed from the monitor (I
think).
Example: -serial null -chardev null,id=chr0 -global isa-serial.chardev=chr0
Special case: attempting to use the same backend both times crashes:
$ qemu-system-x86_64 --nodefaults -serial null -global isa-serial.chardev=serial0
Unexpected error in qemu_chr_fe_init() at /work/armbru/qemu/chardev/char-fe.c:220:
qemu-system-x86_64: Device 'serial0' is in use
Aborted (core dumped)
Yet another example: -device with multiple chardev=... (but not
device_add, which silently drops all but the last duplicate property).
Perhaps chardev property override could be made to work. Perhaps it
should. I can't afford the time to figure this out now. What I can
do reject usage that leaves backends in unhealthy states. For what
it's worth, we've long done the same for netdev properties.

The floppy controller devices desugar their drive properties into
floppy devices (since commit a92bd191a4 "fdc: Move qdev properties to
FloppyDrive", v2.8.0). This involves some bad magic in
fdctrl_connect_drives(), and exists for backward compatibility.
The functions for boards to create floppy controller devices
fdctrl_init_isa(), fdctrl_init_sysbus(), and sun4m_fdctrl_init()
desugar -drive if=floppy to these floppy controller drive properties.
If you use both -drive if=floppy (or its -fda / -fdb sugar) and
-global isa-fdc for the same floppy device, -global silently loses the
conflict, and both backends involved end up with the floppy device
frontend attached, as demonstrated by iotest 172 (see commit before
previous). This is wrong.
Desugar -drive if=floppy straight to floppy devices instead, with
helper fdctrl_init_drives(). The conflict now gets rejected cleanly:
first, fdctrl_connect_drives() creates the floppy for the controller's
property, then fdctrl_init_drives() attempts to create the floppy for
-drive if=floppy, but fails because the unit is already in use.
Output of iotest 172 changes in three ways:
1. The clash gets rejected.
2. In one test case, "info qtree" has the floppy devices swapped, and
"info block" has their QOM paths swapped. This is because the
floppy device for -fda now gets created after the one for -global
isa-fdc.driveB.
3. The error message for -global floppy.drive=floppy0 changes. Before
the patch, we set isa-fdc.driveA to -fda's block backend, then
create the floppy device for it, then move the backend from
isa-fdc.driveA to floppy.drive. Floppy creation fails when
applying -global floppy.drive=floppy0, because floppy0 is still
attached to isa-fdc. After the patch, we create the floppy for
-fda, then set its drive property to floppy0. Now floppy creation
succeeds, but setting the drive property fails, because -global
already set it. Yes, this is exasperatingly complicated.

Use of -global to set a default backend for non-singleton devices is a
bad idea. But as long as we permit it, we better test it.
Test output demonstrates we screw up when -global floppy clashes with
-fda or with -device floppy: according to "info qtree", only the
latter backend is attached, but according to "info block", both are.
Here's the clash with -device:
Testing: -drive if=none,file=TEST_DIR/t.qcow2 -drive if=none,file=TEST_DIR/t.qcow2.2 -global floppy.drive=none0 -device floppy,drive=none1,unit=0
dev: isa-fdc, id ""
[...]
driveA = ""
driveB = ""
[...]
bus: floppy-bus.0
type floppy-bus
dev: floppy, id ""
unit = 0 (0x0)
---> drive = "none1"
[...]
none0 (NODE_NAME): TEST_DIR/t.qcow2 (qcow2)

none1 (NODE_NAME): TEST_DIR/t.qcow2.2 (qcow2)
---> Attached to: /machine/peripheral-anon/device[0]
Removable device: not locked, tray closed
Cache mode: writeback
/machine/peripheral-anon/device[0] is the floppy created with -device.
Test output further demonstrates the "Drive 'FOO' is already in use
because it has been automatically connected to another device" error
message can be misleading. With '-fda "" -global
floppy.drive=floppy0', it's in use because -global reuses -fda's
backend. There is no other device involved.

Fix this by splitting the 64-bit constant into two halves,
each of which is individually perfectly representable, the
sum of which produces the correct arithmetic result.
This is very likely just a sticking plaster over some underlying
incorrect code, but it will suppress the warning for the moment.

It is enough to simply map the SiFive FU540 DDR memory controller
into the MMIO space using create_unimplemented_device(), to make
the upstream U-Boot v2020.07 DDR memory initialization codes happy.
Note we do not generate device tree fragment for the DDR memory
controller. Since the controller data in device tree consumes a
very large space (see fu540-hifive-unleashed-a00-ddr.dtsi in the
U-Boot source), and it is only needed by U-Boot SPL but not any
operating system, we choose not to generate the fragment here.
This also means when testing with U-Boot SPL, the device tree has
to come from U-Boot SPL itself, but not the one generated by QEMU
on the fly. The memory has to be set to 8GiB to match the real
HiFive Unleashed board when invoking QEMU (-m 8G).
With this commit, QEMU can boot U-Boot SPL built for SiFive FU540
all the way up to loading U-Boot proper from MMC:
$ qemu-system-riscv64 -nographic -M sifive_u,msel=6 -m 8G -bios u-boot-spl.bin
U-Boot SPL 2020.07-rc3-00208-g88bd5b1 (Jun 08 2020 - 20:16:10 +0800)
Trying to boot from MMC1
Unhandled exception: Load access fault
EPC: 0000000008009be6 TVAL: 0000000010050014
The above exception is expected because QSPI is unsupported yet.

SiFive FU540 SoC supports booting from several sources, which are
controlled using the Mode Select (MSEL[3:0]) pins on the chip.
Typically, the boot process runs through several stages before it
begins execution of user-provided programs.
The SoC supports booting from memory-mapped QSPI flash, which is
how start_in_flash property is used for at present. This matches
MSEL = 1 configuration (QSPI0).
Typical booting flows involve the Zeroth Stage Boot Loader (ZSBL).
It's not necessary for QEMU to implement the full ZSBL ROM codes,
because we know ZSBL downloads the next stage program into the L2
LIM at address 0x8000000 and executes from there. We can bypass
the whole ZSBL execution and use "-bios" to load the next stage
program directly if MSEL indicates a ZSBL booting flow.

This patch implements a Ibex PLIC in a somewhat generic way.
As the current RISC-V PLIC needs tidying up, my hope is that as the Ibex
PLIC move towards spec compliance this PLIC implementation can be
updated until it can replace the current PLIC.
