target/tricore: Fix helper_ret() not correctly restoring PSW

We are always taking the TRICORE_FEATURE_13 branch as every CPU has TRICORE_FEATURE_13.
For CPUs with ISA > 1.3 we have to take the else branch.

We fix this by inverting the condition. We check for
TRICORE_FEATURE_131, which every CPU except TRICORE_FEATURE_13 CPUs
have.

Revert "cputlb: Restrict SavedIOTLB to system emulation"

This reverts commit d7ee93e24359703debf4137f4cc632563aa4e8d1.

That commit tries to make a field in the CPUState struct not be
present when CONFIG_USER_ONLY is set.  Unfortunately, you can't
conditionally omit fields in structs like this based on ifdefs that
are set per-target.  If you try it, then code in files compiled
per-target (where CONFIG_USER_ONLY is or can be set) will disagree
about the struct layout with files that are compiled once-only (where
this kind of ifdef is never set).

This manifests specifically in 'make check-tcg' failing, because code
in cpus-common.c that sets up the CPUState::cpu_index field puts it
at a different offset from the code in plugins/core.c in
qemu_plugin_vcpu_init_hook() which reads the cpu_index field.  The
latter then hits an assert because from its point of view every
thread has a 0 cpu_index. There might be other weird behaviour too.

Mostly we catch this kind of bug because the CONFIG_whatever is
listed in include/exec/poison.h and so the reference to it in
build-once source files will then cause a compiler error.
Unfortunately CONFIG_USER_ONLY is an exception to that: we have some
places where we use it in "safe" ways in headers that will be seen by
once-only source files (e.g.  ifdeffing out function prototypes) and
it would be a lot of refactoring to be able to get to a position
where we could poison it.  This leaves us in a "you have to be
careful to walk around the bear trap" situation...

imx_serial: set wake bit when we receive a data byte

The Linux kernel added a flood check for RX data recently in commit
496a4471b7c3 ("serial: imx: work-around for hardware RX flood"). This
check uses the wake bit in the UART status register 2. The wake bit
indicates that the receiver detected a start bit on the RX line. If the
kernel sees a number of RX interrupts without the wake bit being set, it
treats this as spurious data and resets the UART port. imx_serial does
never set the wake bit and triggers the kernel's flood check.

This patch adds support for the wake bit. wake is set when we receive a
new character (it's not set for break events). It seems that wake is
cleared by the kernel driver, the hardware does not have to clear it
automatically after data was read.

The wake bit can be configured as an interrupt source. Support this
mechanism as well.

hw/timer/nrf51_timer: Don't lose time when timer is queried in tight loop

The nrf51_timer has a free-running counter which we implement using
the pattern of using two fields (update_counter_ns, counter) to track
the last point at which we calculated the counter value, and the
counter value at that time.  Then we can find the current counter
value by converting the difference in wall-clock time between then
and now to a tick count that we need to add to the counter value.

Unfortunately the nrf51_timer's implementation of this has a bug
which means it loses time every time update_counter() is called.
After updating s->counter it always sets s->update_counter_ns to
'now', even though the actual point when s->counter hit the new value
will be some point in the past (half a tick, say).  In the worst case
(guest code in a tight loop reading the counter, icount mode) the
counter is continually queried less than a tick after it was last
read, so s->counter never advances but s->update_counter_ns does, and
the guest never makes forward progress.

The fix for this is to only advance update_counter_ns to the
timestamp of the last tick, not all the way to 'now'.  (This is the
pattern used in hw/misc/mps2-fpgaio.c's counter.)

hw/sd/allwinner-sdhost: Don't send non-boolean IRQ line levels

QEMU allows qemu_irq lines to transfer arbitrary integers.  However
the convention is that for a simple IRQ line the values transferred
are always 0 and 1.  The A10 SD controller device instead assumes a
0-vs-non-0 convention, which happens to work with the interrupt
controller it is wired up to.

Coerce the value to boolean to follow our usual convention.

hw/intc/allwinner-a10-pic: Handle IRQ levels other than 0 or 1

In commit 2c5fa0778c3b430 we fixed an endianness bug in the Allwinner
A10 PIC model; however in the process we introduced a regression.
This is because the old code was robust against the incoming 'level'
argument being something other than 0 or 1, whereas the new code was
not.

In particular, the allwinner-sdhost code treats its IRQ line
as 0-vs-non-0 rather than 0-vs-1, so when the SD controller
set its IRQ line for any reason other than transmit the
interrupt controller would ignore it. The observed effect
was a guest timeout when rebooting the guest kernel.

Handle level values other than 0 or 1, to restore the old
behaviour.

The LDG instruction loads the tag from a memory address (identified

register Xt. We implemented this correctly for the case when

    Extract common functionalities from hw/i386/xen/xen-hvm.c and move them to

        xen_vcpu_eport(), xen_vcpu_ioreq(), xen_ram_alloc(), xen_set_memory(),
        xen_region_add(), xen_region_del(), xen_io_add(), xen_io_del(),

hw/i386/xen: rearrange xen_hvm_init_pc

In preparation to moving most of xen-hvm code to an arch-neutral location,
move non IOREQ references to:
- xen_get_vmport_regs_pfn
- xen_suspend_notifier
- xen_wakeup_notifier
- xen_ram_init

towards the end of the xen_hvm_init_pc() function.

This is done to keep the common ioreq functions in one place which will be
moved to new function in next patch in order to make it common to both x86 and
aarch64 machines.

target/arm: Allow users to set the number of VFP registers

Cortex A7 CPUs with an FPU implementing VFPv4 without NEON support
have 16 64-bit FPU registers and not 32 registers. Let users set the
number of VFP registers with a CPU property.

The primary use case of this property is for the Cortex A7 of the
Aspeed AST2600 SoC.

aspeed: Introduce a "bmc-console" machine option

Most of the Aspeed machines use the UART5 device for the boot console,
and QEMU connects the first serial Chardev to this SoC device for this
purpose. See routine connect_serial_hds_to_uarts().

Nevertheless, some machines use another boot console, such as the fuji,
and commit 5d63d0c76c ("hw/arm/aspeed: Allow machine to set UART
default") introduced a SoC class attribute 'uart_default' and property
to be able to change the boot console device. It was later changed by
commit d2b3eaefb4 ("aspeed: Refactor UART init for multi-SoC machines").

The "bmc-console" machine option goes a step further and lets the user define
the UART device from the QEMU command line without introducing a new
machine definition. For instance, to use device UART3 (mapped on
/dev/ttyS2 under Linux) instead of the default UART5, one would use :

  -M ast2500-evb,bmc-console=uart3

aspeed: Use the boot_rom region of the fby35 machine

This change completes commits 5aa281d757 ("aspeed: Introduce a
spi_boot region under the SoC") and 8b744a6a47 ("aspeed: Add a
