Change the ppc440_sdram model to a QOM class derived from the
PPC4xx-dcr-device and name it ppc4xx-sdram-ddr2. This is mostly
modelling the DDR2 SDRAM controller found in the 460EX (used on the
sam460ex board). Newer SoCs (regardless of their PPC core, e.g. 405EX)
may have this controller but we only emulate enough of it for the
sam460ex u-boot firmware.

Move the check for valid memory sizes from board to sdram controller
init. This adds the missing valid memory sizes of 16 and 8 MiB to the
DoC and the board now only checks for additional restrictions imposed
by its firmware then sdram init checks for valid sizes for SoC.

Change the ppc4xx_sdram model to a QOM class derived from the
PPC4xx-dcr-device and name it ppc4xx-sdram-ddr. This is mostly
modelling the DDR SDRAM controller found in the 440EP (used on the
bamboo board) but also backward compatible with the older DDR
controllers on some 405 SoCs so we also use it for those now. This
likely does not cause problems for guests we run as the new features
are just not accessed but to model 405 SoC accurately some features
may have to be disabled or the model split between 440 and older.
Newer SoCs (regardless of their PPC core, e.g. 405EX) may have an
updated DDR2 SDRAM controller implemented by the ppc440_sdram model
(only partially, enough for the 460EX on the sam460ex) that is not yet
QOM'ified in this patch. That is intended to become ppc4xx-sdram-ddr2
when QOM'ified later.

The do_init parameter of ppc4xx_sdram_init() is used to map memory
regions that is normally done by the firmware by programming the SDRAM
controller. Do this from board code emulating what firmware would do
when booting a kernel directly from -kernel without a firmware so we
can get rid of this do_init hack.

Previously the 32-bit version was incorrectly chosen, leading to funny

corresponding to the 64-bit asm-generic definition.
For reference, this program should produce the same output no matter
natively compiled or not, for loongarch64 or not:
```c
#include <stdio.h>
#include <sys/statfs.h>
int main(int argc, const char *argv[])

the maximum priority level is from num_priorities Property which is

To boot S-mode firmware payload like EDK2 from persistent
flash storage, qemu needs to pass the flash address as the
next_addr in fw_dynamic_info to the opensbi.
When both -kernel and -pflash options are provided in command line,
the kernel (and initrd if -initrd) will be copied to fw_cfg table.
The S-mode FW will load the kernel/initrd from fw_cfg table.
If only pflash is given but not -kernel, then it is the job of
of the S-mode firmware to locate and load the kernel.
In either case, update the kernel_entry with the flash address
so that the opensbi can jump to the entry point of the S-mode
firmware.

Section 5.6.6.3 of VirtIO specification states, "Events will also
be reported via sense codes..." However, no sense data is sent when
VIRTIO_SCSI_EVT_RESET_RESCAN or VIRTIO_SCSI_EVT_RESET_REMOVED events
are reported (when disk hotplug/hotunplug events occur). SCSI layer
on Solaris depends on this sense data, and hence does not handle disk
hotplug/hotunplug events.
When the disk inventory changes, use the bus unit attention mechanism
to return a CHECK_CONDITION status with sense data of 0x06/0x3F/0x0E
(sense code REPORTED_LUNS_CHANGED). The first device on the bus to
execute a command successfully will report and consume the unit
attention status.

This has been tested under msys2 & windows 11. I haven't tried to make
it work with other environments yet, but that should be enough to
validate the channel-command implementation anyway.
Here are the changes:
- drop tests/ from fifo/pipe path, to avoid directory issues
- use g_find_program() to lookup the socat executable (otherwise we
would need to change ChanneCommand to use G_SPAWN_SEARCH_PATH, and deal
with missing socat differently)
- skip the "echo" test when socat is missing as well

The initial implementation was changing the pipe state created by GLib
to PIPE_NOWAIT, but it turns out it doesn't work (read/write returns an
error). Since reading may return less than the requested amount, it
seems to be non-blocking already. However, the IO operation may block
until the FD is ready, I can't find good sources of information, to be
safe we can just poll for readiness before.
Alternatively, we could setup the FDs ourself, and use UNIX sockets on
Windows, which can be used in blocking/non-blocking mode. I haven't
tried it, as I am not sure it is necessary.

Simplify qio_channel_command_new_spawn() with GSpawn API. This will
allow to build for WIN32 in the following patches.
As pointed out by Daniel Berrangé: there is a change in semantics here
too. The current code only touches stdin/stdout/stderr. Any other FDs
which do NOT have O_CLOEXEC set will be inherited. With the new code,
all FDs except stdin/out/err will be explicitly closed, because we don't
set the flag G_SPAWN_LEAVE_DESCRIPTORS_OPEN. The only place we use
QIOChannelCommand today is the migration exec: protocol, and that is
only declared to use stdin/stdout.

The /io/channel/command/echo tests run the reader side and the writer
side with the same underlying command channel. Setting the blocking mode
of the fd/handles while the other end is already reading/writing may
create issues (deadlock in win32 when earlier attempt of this series
