Allwinner R40 supports two USB host ports shared between a USB 2.0 EHCI
host controller and a USB 1.1 OHCI host controller. Add support for both
of them.
If machine USB support is not enabled, create unimplemented devices
for the USB memory ranges to avoid crashes when booting Linux.

Convert the musicpal key input device to use
qemu_add_kbd_event_handler(). This lets us simplify it because we no
longer need to track whether we're in the middle of a PS/2 multibyte
key sequence.
In the conversion we move the keyboard handler registration from init
to realize, because devices shouldn't disturb the state of the
simulation by doing things like registering input handlers until
they're realized, so that device objects can be introspected
safely.
The behaviour where key-repeat is permitted for the arrow-keys only
is intentional (added in commit 7c6ce4baed), so we retain it,
and add a comment to that effect.
This is a migration compatibility break for musicpal.

It's found that some of the CPU type names in the array of valid
CPU types are invalid because their corresponding classes aren't
registered, as reported by Peter Maydell.

On the vexpress-a9 board we try to map both RAM and flash to address 0,

0000000010004000-0000000010004fff (prio 0, i/o): pl041
(etc)
The flash "wins" and the RAM mapping is useless (but also harmless).
This happened as a result of commit 6ec1588e in 2014, which changed
"we always map the RAM to the low addresses for vexpress-a9" to "we
always map flash in the low addresses", but forgot to stop mapping
the RAM.
In real hardware, this low part of memory is remappable, both at
runtime by the guest writing to a control register, and configurably
as to what you get out of reset -- you can have the first flash
device, or the second, or the DDR2 RAM, or the external AXI bus
(which for QEMU means "nothing there"). In an ideal world we would
support that remapping both at runtime and via a machine property to
select the out-of-reset behaviour.
Pending anybody caring enough to implement the full remapping
behaviour:
* remove the useless mapped-but-inaccessible lowram MR
* document that QEMU doesn't support remapping of low memory

Documentation for using the GAS in ACPI tables to report debug UART addresses at
https://learn.microsoft.com/en-us/windows-hardware/drivers/bringup/acpi-debug-port-table
states the following:
- The Register Bit Width field contains the register stride and must be a
power of 2 that is at least as large as the access size. On 32-bit
platforms this value cannot exceed 32. On 64-bit platforms this value
cannot exceed 64.
- The Access Size field is used to determine whether byte, WORD, DWORD, or
QWORD accesses are to be used. QWORD accesses are only valid on 64-bit
architectures.
Documentation for the ARM PL011 at
https://developer.arm.com/documentation/ddi0183/latest/
states that the registers are:
- spaced 4 bytes apart (see Table 3-2), so register stride must be 32.
- 16 bits in size in some cases (see individual registers), so access
size must be at least 2.
Linux doesn't seem to care about this error in the table, but it does
affect at least the NOVA microhypervisor.
In theory we therefore have a choice between reporting the access
size as 2 (16 bit accesses) or 3 (32-bit accesses). In practice,
Linux does not correctly handle the case where the table reports the
access size as 2: as of kernel commit 750b95887e5678, the code in
acpi_parse_spcr() tries to tell the serial driver to use 16 bit
accesses by passing "mmio16" in the option string, but the PL011
driver code in pl011_console_match() only recognizes "mmio" or
"mmio32". The result is that unless the user has enabled 'earlycon'
there is no console output from the guest kernel.
We therefore choose to report the access size as 32 bits; this works
for NOVA and also for Linux. It is also what the UEFI firmware on a
Raspberry Pi 4 reports, so we're in line with existing real-world
practice.

using PCIIOMMUOps leaves space to add more iommu related

Since we only have one user, take the opportunity to convert

qemu_input_key_value_to_scancode() (which adds an 0xe0
prefix and encodes up/down indication in the scancode,
which our old handler function then had to reverse). That

Implement a model of the Neoverse N2 CPU. This is an Armv9.0-A
processor very similar to the Cortex-A710. The differences are:
* no FEAT_EVT
* FEAT_DGH (data gathering hint)
* FEAT_NV (not yet implemented in QEMU)
* Statistical Profiling Extension (not implemented in QEMU)
* 48 bit physical address range, not 40
* CTR_EL0.DIC = 1 (no explicit icache cleaning needed)
* PMCR_EL0.N = 6 (always 6 PMU counters, not 20)
Because it has 48-bit physical address support, we can use
this CPU in the sbsa-ref board as well as the virt board.

The code for powering on a CPU in arm-powerctl.c has two separate
use cases:
* emulation of a real hardware power controller
* emulation of firmware interfaces (primarily PSCI) with
CPU on/off APIs
For the first case, we only need to reset the CPU and set its
starting PC and X0. For the second case, because we're emulating the
firmware we need to ensure that it's in the state that the firmware
provides. In particular, when we reset to a lower EL than the
highest one we are emulating, we need to put the CPU into a state
that permits correct running at that lower EL. We already do a
little of this in arm-powerctl.c (for instance we set SCR_HCE to
enable the HVC insn) but we don't do enough of it. This means that
in the case where we are emulating EL3 but also providing emulated
PSCI the guest will crash when a secondary core tries to use a
feature that needs an SCR_EL3 bit to be set, such as MTE or PAuth.
The hw/arm/boot.c code also has to support this "start guest code in
an EL that's lower than the highest emulated EL" case in order to do
direct guest kernel booting; it has all the necessary initialization
code to set the SCR_EL3 bits. Pull the relevant boot.c code out into
a separate function so we can share it between there and
arm-powerctl.c.
This refactoring has a few code changes that look like they
might be behaviour changes but aren't:
* if info->secure_boot is false and info->secure_board_setup is
true, then the old code would start the first CPU in Hyp
mode but without changing SCR.NS and NSACR.{CP11,CP10}.
This was wrong behaviour because there's no such thing
as Secure Hyp mode. The new code will leave the CPU in SVC.
(There is no board which sets secure_boot to false and
secure_board_setup to true, so this isn't a behaviour
change for any of our boards.)
* we don't explicitly clear SCR.NS when arm-powerctl.c
does a CPU-on to EL3. This was a no-op because CPU reset
will reset to NS == 0.
And some real behaviour changes:
* we no longer set HCR_EL2.RW when booting into EL2: the guest
can and should do that themselves before dropping into their
EL1 code. (arm-powerctl and boot did this differently; I
opted to use the logic from arm-powerctl, which only sets
HCR_EL2.RW when it's directly starting the guest in EL1,
because it's more correct, and I don't expect guests to be
accidentally depending on our having set the RW bit for them.)
* if we are booting a CPU into AArch32 Secure SVC then we won't
set SCR.HCE any more. This affects only the vexpress-a15 and
raspi2b machine types. Guests booting in this case will either:
- be able to set SCR.HCE themselves as part of moving from
Secure SVC into NS Hyp mode
- will move from Secure SVC to NS SVC, and won't care about
behaviour of the HVC insn
- will stay in Secure SVC, and won't care about HVC
* on an arm-powerctl CPU-on we will now set the SCR bits for
pauth/mte/sve/sme/hcx/fgt features
The first two of these are very minor and I don't expect guest
code to trip over them, so I didn't judge it worth convoluting
the code in an attempt to keep exactly the same boot.c behaviour.
The third change fixes issue 1899.

The SMMUv3.1-XNX feature is mandatory for an SMMUv3.1 if S2P is
supported, so we should theoretically have implemented it as part of
the recent S2P work. Fortunately, for us the implementation is a
no-op.
This feature is about interpretation of the stage 2 page table
descriptor XN bits, which control execute permissions.
For QEMU, the permission bits passed to an IOMMU (via MemTxAttrs and
IOMMUAccessFlags) only indicate read and write; we do not distinguish
data reads from instruction reads outside the CPU proper. In the
SMMU architecture's terms, our interconnect between the client device
and the SMMU doesn't have the ability to convey the INST attribute,
and we therefore use the default value of "data" for this attribute.
We also do not support the bits in the Stream Table Entry that can
override the on-the-bus transaction attribute permissions (we do not
set SMMU_IDR1.ATTR_PERMS_OVR=1).
These two things together mean that for our implementation, it never
has to deal with transactions with the INST attribute, and so it can
correctly ignore the XN bits entirely. So we already implement
FEAT_XNX's "XN field is now 2 bits, not 1" behaviour to the extent
that we need to.
Advertise the presence of the feature in SMMU_IDR3.XNX.
