When setting GLIB_VERSION_MAX_ALLOWED to GLIB_VERSION_2_58 or higher,
glib adds type safety checks to the g_steal_pointer() macro. This
triggers errors in the build_cdat_table() function which uses the
g_steal_pointer() for type-casting from one pointer type to the other
(which also looks quite weird since the local pointers have all been
declared with g_autofree though they are never freed here). Let's fix
it by using a proper typecast instead. For making this possible, we
have to remove the QEMU_PACKED attribute from some structs since GCC
otherwise complains that the source and destination pointer might
have different alignment restrictions. Removing the QEMU_PACKED should
be fine here since the structs are already naturally aligned. Anyway,
add some QEMU_BUILD_BUG_ON() statements to make sure that we've got
the right sizes (without padding in the structs).

When setting GLIB_VERSION_MAX_ALLOWED to GLIB_VERSION_2_58 or higher

type safety checks to the g_steal_pointer() macro. This trigger an
error in the ct3_load_cdat() function: The local char *buf variable is
assigned to uint8_t *buf in CDATObject, i.e. a pointer of a different

The reads to in_clrip[x] registers return rectified input values of the
interrupt sources.
A rectified input value of an interrupt source is defined by the section
"4.5.2 Source configurations (sourcecfg[1]–sourcecfg[1023])" of the RISC-V
AIA specification as:
"rectified input value = (incoming wire value) XOR (source is inverted)"
Update the riscv_aplic_read_input_word() implementation to match the above.

The writes to setipnum_le register in APLIC MSI-mode have special
consideration for level-triggered interrupts as-per section "4.9.2
Special consideration for level-sensitive interrupt sources" of the
RISC-V AIA specification.
Particularly, the below text from the RISC-V specification defines
the behaviour of writes to setipnum_le for level-triggered interrupts:
"A second option is for the interrupt service routine to write the
APLIC’s source identity number for the interrupt to the domain’s
setipnum register just before exiting. This will cause the interrupt’s
pending bit to be set to one again if the source is still asserting
an interrupt, but not if the source is not asserting an interrupt."
Fix setipnum_le write emulation for APLIC MSI-mode by implementing
the above behaviour in riscv_aplic_set_pending() function.

The 'virt' machine makes assumptions on the Advanced Core-Local
Interruptor, or aclint, based on 'tcg_enabled()' conditionals. This
will impact MSI related tests support when adding a RISC-V 'virt' libqos
machine. The accelerator used in that case, 'qtest', isn't being
accounted for and we'll error out if we try to enable aclint.
Create a new virt_aclint_allowed() helper to gate the aclint code
considering both TCG and 'qtest' accelerators. The error message is
left untouched, mentioning TCG only, because we don't expect the
regular user to be aware of 'qtest'.
We want to add 'qtest' support for aclint only, leaving the TCG specific
bits out of it. This is done by changing the current format we use
today:
if (tcg_enabled()) {
if (s->have_aclint) { - aclint logic - }
else { - non-aclint, TCG logic - }
}
into:
if (virt_aclint_allowed() && s->have_aclint) {
- aclint logic -
} else if (tcg_enabled()) {
- non-aclint, TCG logic -
}

Currently, the initrd is placed at 128MB, which overlaps with the kernel
when it is large (for example syzbot kernels are). From the kernel side,
there is no reason we could not push the initrd further away in memory
to accommodate large kernels, so move the initrd at 512MB when possible.
The ideal solution would have been to place the initrd based on the
kernel size but we actually can't since the bss size is not known when
the image is loaded by load_image_targphys_as() and the initrd would
then overlap with this section.

Features supported :
- the 8 STM32L4x5 GPIOs are initialized with their reset values
(except IDR, see below)
- input mode : setting a pin in input mode "externally" (using input
irqs) results in an out irq (transmitted to SYSCFG)
- output mode : setting a bit in ODR sets the corresponding out irq
(if this line is configured in output mode)
- pull-up, pull-down
- push-pull, open-drain
Difference with the real GPIOs :
- Alternate Function and Analog mode aren't implemented :
pins in AF/Analog behave like pins in input mode
- floating pins stay at their last value
- register IDR reset values differ from the real one :
values are coherent with the other registers reset values
and the fact that AF/Analog modes aren't implemented
- setting I/O output speed isn't supported
- locking port bits isn't supported
- ADC function isn't supported
- GPIOH has 16 pins instead of 2 pins
- writing to registers LCKR, AFRL, AFRH and ASCR is ineffective

This patch adds loopback for sent characters, sent BREAK,
and modem-control signals.
Loopback of send and modem-control is often used for uart
self tests in real hardware but missing from current pl011
model, resulting in self-test failures when running in QEMU.
This implementation matches what is observed in real pl011
hardware placed in loopback mode:
1. Input characters and BREAK events from serial backend
are ignored, but
2. Both TX characters and BREAK events are still sent to
serial backend, in addition to be looped back to RX.

2. Repeated starts are not emulated. Repeated starts can be triggered in real

transfer active set of write transfer request and done bit set of the same.

Since Windows text files use CRLFs for all \n, the Windows version of QEMU
inserts a CR in the PCAP stream when a LF is encountered when using USB PCAP
files. This is due to the fact that the PCAP file is opened as TEXT instead
of BINARY.
To show an example, when using a very common protocol to USB disks, the BBB
protocol uses a 10-byte command packet. For example, the READ_CAPACITY(10)
command will have a command block length of 10 (0xA). When this 10-byte
command (part of the 31-byte CBW) is placed into the PCAP file, the Windows
file manager inserts a 0xD before the 0xA, turning the 31-byte CBW into a
32-byte CBW.
Actual CBW:
0040 55 53 42 43 01 00 00 00 08 00 00 00 80 00 0a 25 USBC...........%
0050 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ...............
PCAP CBW
0040 55 53 42 43 01 00 00 00 08 00 00 00 80 00 0d 0a USBC............
0050 25 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 %..............
I believe simply opening the PCAP file as BINARY instead of TEXT will fix
this issue.

The UEFI loading mode in loongarch is very different
from that in other architectures:loongarch's UEFI code
is in rom, while other architectures' UEFI code is in flash.
loongarch UEFI can be loaded as follows:
-machine virt,pflash=pflash0-format
-bios ./QEMU_EFI.fd
Other architectures load UEFI using the following methods:
-machine virt,pflash0=pflash0-format,pflash1=pflash1-format
loongarch's UEFI loading method makes qemu and libvirt incompatible
when using NVRAM, and the cost of loongarch's current loading method
far outweighs the benefits, so we decided to use the same UEFI loading
scheme as other architectures.
