The macro used to calculate the maximum memory size of the MMIO region
had a mistake, causing all GPIO models to create a mapping of 0x9D8.
The intent was to have it be 0x9D8 - 0x800.
This extra size doesn't matter on ast2400 and ast2500, which have a 4KB
region set aside for the GPIO controller.
On the ast2600 the 3.3V and 1.8V GPIO controllers are 2KB apart, so the
regions would overlap. Worse was the 1.8V controller would map over the
top of the following peripheral, which happens to be the RTC.
The mmio region used by each device is a maximum of 2KB, so avoid the
calculations and hard code this as the maximum.

In Arm v8.1M the VECTPENDING field in the ICSR has new behaviour: if
the register is accessed NonSecure and the highest priority pending

The ISCR.ISRPENDING bit is set when an external interrupt is pending.
This is true whether that external interrupt is enabled or not.
This means that we can't use 's->vectpending == 0' as a shortcut to
"ISRPENDING is zero", because s->vectpending indicates only the
highest priority pending enabled interrupt.
Remove the incorrect optimization so that if there is no pending
enabled interrupt we fall through to scanning through the whole
interrupt array.

For M-profile, we weren't reporting alignment faults triggered by the
generic TCG code correctly to the guest. These get passed into
arm_v7m_cpu_do_interrupt() as an EXCP_DATA_ABORT with an A-profile
style exception.fsr value of 1. We didn't check for this, and so
they fell through into the default of "assume this is an MPU fault"
and were reported to the guest as a data access violation MPU fault.
Report these alignment faults as UsageFaults which set the UNALIGNED
bit in the UFSR.

In do_v7m_exception_exit(), we perform various checks as part of
performing the exception return. If one of these checks fails, the
architecture requires that we take an appropriate exception on the
existing stackframe. We implement this by calling
v7m_exception_taken() to set up to take the new exception, and then
immediately returning from do_v7m_exception_exit() without proceeding
any further with the unstack-and-exception-return process.
In a couple of checks that are new in v8.1M, we forgot the "return"
statement, with the effect that if bad code in the guest tripped over
these checks we would set up to take a UsageFault exception but then
blunder on trying to also unstack and return from the original
exception, with the probable result that the guest would crash.
Add the missing return statements.

For M-profile, unlike A-profile, the low 2 bits of SP are defined to be
RES0H, which is to say that they must be hardwired to zero so that
guest attempts to write non-zero values to them are ignored.
Implement this behaviour by masking out the low bits:
* for writes to r13 by the gdbstub
* for writes to any of the various flavours of SP via MSR
* for writes to r13 via store_reg() in generated code
Note that all the direct uses of cpu_R[] in translate.c are in places
where the register is definitely not r13 (usually because that has
been checked for as an UNDEFINED or UNPREDICTABLE case and handled as
UNDEF).
All the other writes to regs[13] in C code are either:
* A-profile only code
* writes of values we can guarantee to be aligned, such as
- writes of previous-SP-value plus or minus a 4-aligned constant
- writes of the value in an SP limit register (which we already
enforce to be aligned)

Prior to this patch the nvme-ns devices are always children of the
NvmeBus owned by the NvmeCtrl. This causes the namespaces to be
unrealized when the parent device is removed. However, when subsystems
are involved, this is not what we want since the namespaces may be
attached to other controllers as well.
This patch adds an additional NvmeBus on the subsystem device. When
nvme-ns devices are realized, if the parent controller device is linked
to a subsystem, the parent bus is set to the subsystem one instead. This
makes sure that namespaces are kept alive and not unrealized.

We currently lack the infrastructure to handle subsystem hotplugging, so
disable it.

The nvme_ns_setup and nvme_ns_check_constraints should not depend on the
controller state. Refactor and remove it.

It's pretty clear that we meant to write back 'v' after
all that computation and not 'val'.

Quite right of course, but there's no reason not to check errors.
First, incrementing errors is incorrect, because qemu_strtoul
returns an errno not a count -- just or them together so that
we have a non-zero value at the end.
Second, if we have an error, do not add the struct to the list,
but free it instead.

Commit db1ffc32dd ("qemu/bitops.h: add bitrev8 implementation") introduced
a bitrev8() function to reverse the bit ordering required for storing the
MAC address in the q800 PROM.
This function is not required since QEMU implements its own revbit8()
function which does exactly the same thing. Remove the extraneous
bitrev8() function and switch its only caller in hw/m68k/q800.c to
use revbit8() instead.

In cpu_loop_exec_tb(), we decide whether to look for a TB with
exactly insns_left instructions in it using the condition
(!cpu->icount_extra && insns_left > 0 && insns_left < tb->icount)
The check for icount_extra == 0 is unnecessary, because we just set
insns_left = MIN(0xffff, cpu->icount_budget);
icount_extra = icount_budget - insns_left;
and so icount_extra can only be non-zero if icount_budget > 0xffff
and insns_left == 0xffff. But in that case insns_left >= tb->icount
because 0xffff is much larger than TCG_MAX_INSNS, so the condition
will be false anyway.
Remove the unnecessary check, and instead assert:
* that we are only going to execute a partial TB here if the
icount budget has run out (ie icount_extra == 0)
* that the number of insns we're going to execute does fit into
the CF_COUNT_MASK
