It is irrelevant to the API what the buffers to fill are made of.
In particular, some MIPS ISA have 16-bit wide instructions.

This patch enables copying of SPL from MMC if `-kernel` parameter is not

This patch implements Allwinner TWI/I2C controller emulation. Only
master-mode functionality is implemented.
The SPL boot for Cubieboard expects AXP209 PMIC on TWI0/I2C0 bus, so this is
first part enabling the TWI/I2C bus operation.
Since both Allwinner A10 and H3 use the same module, it is added for
both boards.
Docs are also updated for Cubieboard and Orangepi-PC board to indicate
I2C availability.

During SPL boot several DRAM Controller registers are used. Most
important registers are those related to DRAM initialization and
calibration, where SPL initiates process and waits until certain bit is
set/cleared.
This patch adds these registers, initializes reset values from user's

If we update an existing memslot (e.g., resize, split), we temporarily
remove the memslot to re-add it immediately afterwards. These updates
are not atomic, especially not for KVM VCPU threads, such that we can
get spurious faults.
Let's inhibit most KVM ioctls while performing relevant updates, such
that we can perform the update just as if it would happen atomically
without additional kernel support.
We capture the add/del changes and apply them in the notifier commit
stage instead. There, we can check for overlaps and perform the ioctl
inhibiting only if really required (-> overlap).
To keep things simple we don't perform additional checks that wouldn't
actually result in an overlap -- such as !RAM memory regions in some
cases (see kvm_set_phys_mem()).
To minimize cache-line bouncing, use a separate indicator
(in_ioctl_lock) per CPU. Also, make sure to hold the kvm_slots_lock
while performing both actions (removing+re-adding).
We have to wait until all IOCTLs were exited and block new ones from
getting executed.
This approach cannot result in a deadlock as long as the inhibitor does
not hold any locks that might hinder an IOCTL from getting finished and
exited - something fairly unusual. The inhibitor will always hold the BQL.
AFAIKs, one possible candidate would be userfaultfd. If a page cannot be
placed (e.g., during postcopy), because we're waiting for a lock, or if the
userfaultfd thread cannot process a fault, because it is waiting for a
lock, there could be a deadlock. However, the BQL is not applicable here,
because any other guest memory access while holding the BQL would already
result in a deadlock.
Nothing else in the kernel should block forever and wait for userspace
intervention.
Note: pause_all_vcpus()/resume_all_vcpus() or
start_exclusive()/end_exclusive() cannot be used, as they either drop
the BQL or require to be called without the BQL - something inhibitors
cannot handle. We need a low-level locking mechanism that is
deadlock-free even when not releasing the BQL.

This API allows the accelerators to prevent vcpus from issuing
new ioctls while execting a critical section marked with the
accel_ioctl_inhibit_begin/end functions.
Note that all functions submitting ioctls must mark where the
ioctl is being called with accel_{cpu_}ioctl_begin/end().
This API requires the caller to always hold the BQL.
API documentation is in sysemu/accel-blocker.h
Internally, it uses a QemuLockCnt together with a per-CPU QemuLockCnt
(to minimize cache line bouncing) to keep avoid that new ioctls
run when the critical section starts, and a QemuEvent to wait
that all running ioctls finish.

Currently we'll always generate a cluster node no matter user has
specified '-smp clusters=X' or not. Cluster is an optional level
and will participant the building of Linux scheduling domains and
only appears on a few platforms. It's unncessary to always build
it when it cannot reflect the real topology on platforms having no
cluster implementation and to avoid affecting the linux scheduling
domains in the VM. So only generate the cluster topology in ACPI
PPTT when the user has specified it explicitly in -smp.
Tested qemu-system-aarch64 with `-smp 8` and linux 6.1-rc1, without
this patch:
estuary:/sys/devices/system/cpu/cpu0/topology$ cat cluster_*
ff # cluster_cpus
0-7 # cluster_cpus_list
56 # cluster_id
with this patch:
estuary:/sys/devices/system/cpu/cpu0/topology$ cat cluster_*
ff # cluster_cpus
0-7 # cluster_cpus_list
36 # cluster_id, with no cluster node kernel will make it to

This patch aims to fix unexpected negotiation features for
vhost-user netdev interface.
When openvswitch reconnect Qemu after an unexpected disconnection
and Qemu therefore start the vhost_dev, acked_features field in
vhost_dev is initialized with value fetched from acked_features
field in NetVhostUserState, which should be up-to-date at that
moment but Qemu could not make it actually during the time window
of virtio features negotiation.
So we save the acked_features right after being configured by
guest virtio driver so it can be used to restore acked_features
field in vhost_dev correctly.

At present the SiFive PLIC model "priority-base" expects interrupt
priority register base starting from source 1 instead source 0,
that's why on most platforms "priority-base" is set to 0x04 except
'opentitan' machine. 'opentitan' should have set "priority-base"
to 0x04 too.
Note the irq number calculation in sifive_plic_{read,write} is
correct as the codes make up for the irq number by adding 1.
Let's simply update "priority-base" to start from interrupt source
0 and add a comment to make it crystal clear.

Commit 28d8c281200f ("hw/riscv: virt: Add optional AIA IMSIC support to virt machine")
changed the value of VIRT_IRQCHIP_NUM_SOURCES from 127 to 53, which
is VIRTIO_NDEV and also used as the value of "riscv,ndev" property
in the dtb. Unfortunately this is wrong as VIRT_IRQCHIP_NUM_SOURCES
should include interrupt source 0 but "riscv,ndev" does not.
While we are here, we also fix the comments of platform bus irq range
which is now "64 to 96", but should be "64 to 95", introduced since
commit 1832b7cb3f64 ("hw/riscv: virt: Create a platform bus").

Per chapter 10 in Freedom E310 manuals [1][2][3], E310 G002 and G003
supports 52 interrupt sources while G000 supports 51 interrupt sources.
We use the value of G002 and G003, so it is 53 (including source 0).
