Add basic implementation of the AC'97 sound part used in VIA south
bridge chips. Not all features of the device is emulated, only one
playback channel is supported for now but this is enough to get sound
output from some guests using this device on pegasos2.

According to the PegasosII schematics the PCI interrupt lines are
connected to both the gpp pins of the Mv64361 north bridge and the
PINT pins of the VT8231 south bridge so guests can get interrupts from
either of these. So far we only had the MV64361 connections which
worked for on board devices but for additional PCI devices (such as
network or sound card added with -device) guest OSes expect interrupt
from the ISA IRQ 9 where the firmware routes these PCI interrupts in
VT8231 ISA bridge. After the previous patches we can now model this
and also remove the board specific connection from mv64361. Also
configure routing of these lines when using Virtual Open Firmware to
match board firmware for guests that expect this.
This fixes PCI interrupts on pegasos2 under Linux, MorphOS and AmigaOS.

The real VIA south bridges implement a PCI IRQ router which is configured
by the BIOS or the OS. In order to respect these configurations, QEMU
needs to implement it as well. The real chip may allow routing IRQs from
internal functions independently of PCI interrupts but since guests
usually configute it to a single shared interrupt we don't model that
here for simplicity.
Note: The implementation was taken from piix4_set_irq() in hw/isa/piix4.

Back in the mists of time, before EISA came along and required per-pin
level control in the ELCR register, the i8259 had a single chip-wide
level-mode control in bit 3 of ICW1.
Even in the PIIX3 datasheet from 1996 this is documented as 'This bit is
disabled', but apparently MorphOS is using it in the version of the
i8259 which is in the Pegasos2 board as part of the VT8231 chipset.
It's easy enough to implement, and I think it's harmless enough to do so
unconditionally.

To be 'usable', QDev objects (which are QOM objects) must be
1/ initialized (at this point their properties can be modified), then
2/ realized (properties are consumed).
Some devices (objects) might depend on other devices. When creating
the 'QOM composition tree', parent objects can't be 'realized' until
all their children are. We might also have circular dependencies.
A common circular dependency occurs with IRQs. Device (A) has an
output IRQ wired to device (B), and device (B) has one to device (A).
When (A) is realized and connects its IRQ to an unrealized (B), the
IRQ handler on (B) is not yet created. QEMU pass IRQ between objects
as pointer. When (A) poll (B)'s IRQ, it is NULL. Later (B) is realized
and its IRQ pointers are populated, but (A) keeps a reference to a
NULL pointer.
A common pattern to bypass this circular limitation is to use 'proxy'
objects. Proxy (P) is created (and realized) before (A) and (B). Then
(A) and (B) can be created in different order, it doesn't matter: (P)
pointers are already populated.
Commit bb98e0f59c ("hw/isa/vt82c686: Remove intermediate IRQ
forwarder") neglected the QOM/QDev circular dependency issue, and
removed the 'proxy' between the southbridge, its PCI functions and the
interrupt controller, resulting in PCI functions wiring output IRQs to
'NULL', leading to guest failures (IRQ never delivered) [1] [2].
Since we are entering feature freeze, it is safer to revert the
offending patch until we figure a way to strengthen our APIs.

QOM objects shouldn't access each other internals fields
except using the QOM API.
mips_cps_realize() instantiates a TYPE_MIPS_ITU object, and
directly sets the 'saar' pointer:
if (saar_present) {
s->itu.saar = &env->CP0_SAAR;
}
In order to avoid that, pass the MIPS_CPU object via a QOM
link property, and set the 'saar' pointer in mips_itu_realize().

microMIPS J & JAL instructions perform a jump in a 128MB region and 5
top bits of the address need to be preserved. This is different behavior
compared to standard mips systems, where the jump is executed within a
256MB region.
Note that microMIPS32 instruction set documentation appears to have
inconsistent information regarding JALX32 instruction - it is written in
the doc that:
"To execute a procedure call within the current 256 MB-aligned region
(...)
The low 26 bits of the target address is the target field shifted left
2 bits."
But the target address is already 26 bits. Moreover, the operation
description indicates that 28 bits are copied, so the statement about
use of 26 bits is _most likely_ incorrect and the corresponding code
remains the same as for standard mips instruction set.

Currently, the max satp mode is set with the only constraint that it must be
implemented in QEMU, i.e. set in valid_vm_1_10_[32|64].
But we actually need to add another level of constraint: what the hw is
actually capable of, because currently, a linux booting on a sifive-u54
boots in sv57 mode which is incompatible with the cpu's sv39 max
capability.
So add a new bitmap to RISCVSATPMap which contains this capability and
initialize it in every XXX_cpu_init.
Finally:
- valid_vm_1_10_[32|64] constrains which satp mode the CPU can use
- the CPU hw capabilities constrains what the user may select
- the user's selection then constrains what's available to the guest
OS.

RISC-V specifies multiple sizes for addressable memory and Linux probes for
the machine's support at startup via the satp CSR register (done in
csr.c:validate_vm).
As per the specification, sv64 must support sv57, which in turn must
support sv48...etc. So we can restrict machine support by simply setting the
"highest" supported mode and the bare mode is always supported.
You can set the satp mode using the new properties "sv32", "sv39", "sv48",
"sv57" and "sv64" as follows:
-cpu rv64,sv57=on # Linux will boot using sv57 scheme
-cpu rv64,sv39=on # Linux will boot using sv39 scheme
-cpu rv64,sv57=off # Linux will boot using sv48 scheme
-cpu rv64 # Linux will boot using sv57 scheme by default
We take the highest level set by the user:
-cpu rv64,sv48=on,sv57=on # Linux will boot using sv57 scheme
We make sure that invalid configurations are rejected:
-cpu rv64,sv39=off,sv48=on # sv39 must be supported if higher modes are
# enabled
We accept "redundant" configurations:
-cpu rv64,sv48=on,sv57=off # Linux will boot using sv48 scheme
And contradictory configurations:
-cpu rv64,sv48=on,sv48=off # Linux will boot using sv39 scheme

This array is actually used as a boolean so swap its current char type
to a boolean and at the same time, change the type of validate_vm to

Fedora 39 will ship its arm64 kernels in the new generic EFI zboot
format, using gzip compression for the payload.
For doing EFI boot in QEMU, this is completely transparent, as the
firmware or bootloader will take care of this. However, for direct
kernel boot without firmware, we will lose the ability to boot such
distro kernels unless we deal with the new format directly.
EFI zboot images contain metadata in the header regarding the placement
of the compressed payload inside the image, and the type of compression
used. This means we can wire up the existing gzip support without too
much hassle, by parsing the header and grabbing the payload from inside
the loaded zboot image.

This reverts 49ba115bb7, which was incorrect -- there is nothing
in the ARM pseudocode that depends on TxSZ, i.e. outputsize; the
pseudocode is consistent in referencing PAMax.
