Commit b1f1e9dcfa renamed 'riscv,delegate' to 'riscv,delegation' since
it is the correct name as per dt-bindings, and the absence of the
correct name will result in validation fails when dumping the dtb and
using dt-validate.
But this change has a side-effect: every other firmware available that
is AIA capable is using 'riscv,delegate', and it will fault/misbehave if
this property isn't present. The property was added back in QEMU 7.0,
meaning we have 2 years of firmware development using the wrong
property.
Re-introducing 'riscv,delegate' while keeping 'riscv,delegation' allows
older firmwares to keep booting with the 'virt' machine.
'riscv,delegate' is then marked for future deprecation with its use
being discouraged from now on.

RISC-V virt is currently missing default type for block devices. Without
this being set, proper backend is not created when option like -cdrom
is used. So, make the virt board's default block device type be
IF_VIRTIO similar to other architectures.
We also need to set no_cdrom to avoid getting a default cdrom device.

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.

A few months ago I submitted a patch to various lists, deprecating
"riscv,isa" with a lengthy commit message [0] that is now commit
aeb71e42caae ("dt-bindings: riscv: deprecate riscv,isa") in the Linux
kernel tree. Primarily, the goal was to replace "riscv,isa" with a new
set of properties that allowed for strictly defining the meaning of
various extensions, where "riscv,isa" was tied to whatever definitions
inflicted upon us by the ISA manual, which have seen some variance over
time.
Two new properties were introduced: "riscv,isa-base" and
"riscv,isa-extensions". The former is a simple string to communicate the
base ISA implemented by a hart and the latter an array of strings used
to communicate the set of ISA extensions supported, per the definitions
of each substring in extensions.yaml [1]. A beneficial side effect was
also the ability to define vendor extensions in a more "official" way,
as the ISA manual and other RVI specifications only covered the format
for vendor extensions in the ISA string, but not the meaning of vendor
extensions, for obvious reasons.
Add support for setting these two new properties in the devicetrees for
the various devicetree platforms supported by QEMU for RISC-V. The Linux
kernel already supports parsing ISA extensions from these new
properties, and documenting them in the dt-binding is a requirement for
new extension detection being added to the kernel.
A side effect of the implementation is that the meaning for elements in
"riscv,isa" and in "riscv,isa-extensions" are now tied together as they
are constructed from the same source. The same applies to the ISA string
provided in ACPI tables, but there does not appear to be any strict
definitions of meanings in ACPI land either.

QEMU already implements zicbom (Cache Block Management Operations) and
zicboz (Cache Block Zero Operations). Commit 59cb29d6a5 ("target/riscv:
add Zicbop cbo.prefetch{i, r, m} placeholder") added placeholders for
what would be the instructions for zicbop (Cache Block Prefetch
Operations), which are now no-ops.
The RVA22U64 profile mandates zicbop, which means that applications that
run with this profile might expect zicbop to be present in the riscv,isa
DT and might behave badly if it's absent.
Adding zicbop as an extension will make our future RVA22U64
implementation more in line with what userspace expects and, if/when
cache block prefetch operations became relevant to QEMU, we already have
the extension flag to turn then on/off as needed.

The interrupts-extended property of PLIC only has 2 * hart number
fields when KVM enabled, copy 4 * hart number fields to fdt will
expose some uninitialized value.
In this patch, I also refactor the code about the setting of
interrupts-extended property of PLIC for improved readability.
