e229a179a5 hw: aspeed_gpio: Fix memory size
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.

0642e159d2 hw/gpio/pl061: Document a shortcoming in our implementation
The Luminary PL061s in the Stellaris LM3S9695 don't all have the same
reset value for GPIOPUR.  We can get away with not letting the board
configure the PUR reset value because we don't actually wire anything
up to the lines which should reset to pull-up.  Add a comment noting
this omission.

ef4989b0a8 hw/gpio/pl061: Convert to 3-phase reset and assert GPIO lines correctly on reset
The PL061 comes out of reset with all its lines configured as input,
which means they might need to be pulled to 0 or 1 depending on the
'pullups' and 'pulldowns' properties.  Currently we do not assert
these lines on reset; they will only be set whenever the guest first
touches a register that triggers a call to pl061_update().

Convert the device to three-phase reset so we have a place where we
can safely call qemu_set_irq() to set the floating lines to their
correct values.

c1e69e92ae hw/gpio/pl061: Make pullup/pulldown of outputs configurable
The PL061 GPIO does not itself include pullup or pulldown resistors
to set the value of a GPIO line treated as an output when it is
configured as an input (ie when the PL061 itself is not driving it).
In real hardware it is up to the board to add suitable pullups or
pulldowns.  Currently our implementation hardwires this to "outputs
pulled high", which is correct for some boards (eg the realview ones:
see figure 3-29 in the "RealView Platform Baseboard for ARM926EJ-S
User Guide" DUI0224I), but wrong for others.

In particular, the wiring in the 'virt' board and the gpio-pwr device
assumes that wires should be pulled low, because otherwise the
pull-to-high will trigger a shutdown or reset action.  (The only
reason this doesn't happen immediately on startup is due to another
bug in the PL061, where we don't assert the GPIOs to the correct
value on reset, but will do so as soon as the guest touches a
register and pl061_update() gets called.)

Add properties to the pl061 so the board can configure whether it
wants GPIO lines to have pullup, pulldown, or neither.

ad06d56fc7 hw/gpio/pl061: Honour Luminary PL061 PUR and PDR registers
The Luminary variant of the PL061 has registers GPIOPUR and GPIOPDR
which lets the guest configure whether the GPIO lines are pull-up,
pull-down, or truly floating. Instead of assuming all lines are pulled
high, honour the PUR and PDR registers.

For the plain PL061, continue to assume that lines have an external
pull-up resistor, as we did before.

The stellaris board actually relies on this behaviour -- the CD line
of the ssd0323 display device is connected to GPIO output C7, and it
is only because of a different bug which we're about to fix that we
weren't incorrectly driving this line high on reset and putting the
ssd0323 into data mode.

e24a9f6a59 hw/gpio/pl061: Clean up read/write offset handling logic
Currently the pl061_read() and pl061_write() functions handle offsets
using a combination of three if() statements and a switch().  Clean
this up to use just a switch, using case ranges.

This requires that instead of catching accesses to the luminary-only
registers on a stock PL061 via a check on s->rsvd_start we use
an "is this luminary?" check in the cases for each luminary-only
register.

526dbbe087 hw/gpio: Add GPIO model for Nuvoton NPCM7xx
The NPCM7xx chips have multiple GPIO controllers that are mostly
identical except for some minor differences like the reset values of
some registers. Each controller controls up to 32 pins.

Each individual pin is modeled as a pair of unnamed GPIOs -- one for
emitting the actual pin state, and one for driving the pin externally.
Like the nRF51 GPIO controller, a gpio level may be negative, which
means the pin is not driven, or floating.

4921a0ce86 hw/riscv: Move sifive_gpio model to hw/gpio
This is an effort to clean up the hw/riscv directory. Ideally it
should only contain the RISC-V SoC / machine codes plus generic
codes. Let's move sifive_gpio model to hw/gpio directory.

Note this also removes the trace-events in the hw/riscv directory,
since gpio is the only supported trace target in that directory.

db1015e92e Move QOM typedefs and add missing includes
Some typedefs and macros are defined after the type check macros.
This makes it difficult to automatically replace their
definitions with OBJECT_DECLARE_TYPE.

Patch generated using:

 $ ./scripts/codeconverter/converter.py -i \
   --pattern=QOMStructTypedefSplit $(git grep -l '' -- '*.[ch]')

which will split "typdef struct { ... } TypedefName"
declarations.

Followed by:

 $ ./scripts/codeconverter/converter.py -i --pattern=MoveSymbols \
    $(git grep -l '' -- '*.[ch]')

which will:
- move the typedefs and #defines above the type check macros
- add missing #include "qom/object.h" lines if necessary

243af0225a trace: switch position of headers to what Meson requires
Meson doesn't enjoy the same flexibility we have with Make in choosing
the include path.  In particular the tracing headers are using
$(build_root)/$(<D).

In order to keep the include directives unchanged,
the simplest solution is to generate headers with patterns like
"trace/trace-audio.h" and place forwarding headers in the source tree
such that for example "audio/trace.h" includes "trace/trace-audio.h".

This patch is too ugly to be applied to the Makefiles now.  It's only
a way to separate the changes to the tracing header files from the
Meson rewrite of the tracing logic.

    -    Error *err = NULL;
         ... when != err

Not exactly elegant, I'm afraid.

The "when != lbl:" is necessary to avoid transforming

         if (fun(args, &err)) {
             goto out
         }
         ...
     out:
         error_propagate(errp, err);

even though other paths to label out still need the error_propagate().
For an actual example, see sclp_realize().

Without the "when strict", Coccinelle transforms vfio_msix_setup(),
incorrectly.  I don't know what exactly "when strict" does, only that
it helps here.

The match of return is narrower than what I want, but I can't figure
out how to express "return where the operand doesn't use @err".  For
an example where it's too narrow, see vfio_intx_enable().

Silently fails to convert hw/arm/armsse.c, because Coccinelle gets
confused by ARMSSE being used both as typedef and function-like macro
there.  Converted manually.

Line breaks tidied up manually.  One nested declaration of @local_err
deleted manually.  Preexisting unwanted blank line dropped in
hw/riscv/sifive_e.c.

a0a8cf78e0 hw/gpio/zaurus.c: Use LOG_GUEST_ERROR for bad guest register accesses
Instead of logging guest accesses to invalid register offsets in this
device using zaurus_printf() (which just prints to stderr), use the
usual qemu_log_mask(LOG_GUEST_ERROR,...).

Since this was the only use of the zaurus_printf() macro outside
spitz.c, we can move the definition of that macro from sharpsl.h
to spitz.c.

d2623129a7 qom: Drop parameter @errp of object_property_add() & friends
The only way object_property_add() can fail is when a property with
the same name already exists.  Since our property names are all
hardcoded, failure is a programming error, and the appropriate way to
handle it is passing &error_abort.

Same for its variants, except for object_property_add_child(), which
additionally fails when the child already has a parent.  Parentage is
also under program control, so this is a programming error, too.

We have a bit over 500 callers.  Almost half of them pass
&error_abort, slightly fewer ignore errors, one test case handles
errors, and the remaining few callers pass them to their own callers.

The previous few commits demonstrated once again that ignoring
programming errors is a bad idea.

Of the few ones that pass on errors, several violate the Error API.
The Error ** argument must be NULL, &error_abort, &error_fatal, or a
pointer to a variable containing NULL.  Passing an argument of the
latter kind twice without clearing it in between is wrong: if the
first call sets an error, it no longer points to NULL for the second
call.  ich9_pm_add_properties(), sparc32_ledma_realize(),
sparc32_dma_realize(), xilinx_axidma_realize(), xilinx_enet_realize()
are wrong that way.

When the one appropriate choice of argument is &error_abort, letting
users pick the argument is a bad idea.

Drop parameter @errp and assert the preconditions instead.

There's one exception to "duplicate property name is a programming
error": the way object_property_add() implements the magic (and
undocumented) "automatic arrayification".  Don't drop @errp there.
Instead, rename object_property_add() to object_property_try_add(),
and add the obvious wrapper object_property_add().

3ab5a6ece5 hw/*/Makefile.objs: Move many .o files to common-objs
We have many files that apparently do not depend on the target CPU
configuration, i.e. which can be put into common-obj-y instead of
obj-y. This way, the code can be shared for example between
qemu-system-arm and qemu-system-aarch64, or the various big and
little endian variants like qemu-system-sh4 and qemu-system-sh4eb,
so that we do not have to compile the code multiple times anymore.

4f67d30b5e qdev: set properties with device_class_set_props()
The following patch will need to handle properties registration during
class_init time. Let's use a device_class_set_props() setter.

7811ce8185 hw/gpio: Fix property accessors of the AST2600 GPIO 1.8V model
The property names of AST2600 GPIO 1.8V model are one character bigger
than the names of the other ASPEED GPIO model. Increase the string
buffer size by one and be more strict on the expected pattern of the
property name.

This fixes the QOM test of the ast2600-evb machine under :

4b7f956862 hw/gpio: Add basic Aspeed GPIO model for AST2400 and AST2500
GPIO pins are arranged in groups of 8 pins labeled A,B,..,Y,Z,AA,AB,AC.
(Note that the ast2400 controller only goes up to group AB).
A set has four groups (except set AC which only has one) and is
referred to by the groups it is composed of (eg ABCD,EFGH,...,YZAAAB).
Each set is accessed and controlled by a bank of 14 registers.

These registers operate on a per pin level where each bit in the register
corresponds to a pin, except for the command source registers. The command
source registers operate on a per group level where bits 24, 16, 8 and 0
correspond to each group in the set.

 eg. registers for set ABCD:
 |D7...D0|C7...C0|B7...B0|A7...A0| <- GPIOs
 |31...24|23...16|15....8|7.....0| <- bit position

Note that there are a couple of groups that only have 4 pins.

There are two ways that this model deviates from the behaviour of the
actual controller:
(1) The only control source driving the GPIO pins in the model is the ARM
model (as there currently aren't models for the LPC or Coprocessor).

(2) None of the registers in the model are reset tolerant (needs
integration with the watchdog).

a27bd6c779 Include hw/qdev-properties.h less
In my "build everything" tree, changing hw/qdev-properties.h triggers
a recompile of some 2700 out of 6600 objects (not counting tests and
objects that don't depend on qemu/osdep.h).

Many places including hw/qdev-properties.h (directly or via hw/qdev.h)
actually need only hw/qdev-core.h.  Include hw/qdev-core.h there
instead.

hw/qdev.h is actually pointless: all it does is include hw/qdev-core.h
and hw/qdev-properties.h, which in turn includes hw/qdev-core.h.
Replace the remaining uses of hw/qdev.h by hw/qdev-properties.h.

While there, delete a few superfluous inclusions of hw/qdev-core.h.

Touching hw/qdev-properties.h now recompiles some 1200 objects.

In my "build everything" tree, changing hw/hw.h triggers a recompile
of some 2600 out of 6600 objects (not counting tests and objects that
don't depend on qemu/osdep.h).

The previous commits have left only the declaration of hw_error() in
hw/hw.h.  This permits dropping most of its inclusions.  Touching it
now recompiles less than 200 objects.

hw/hw.h supposedly includes it for convenience.  Several other headers
include it just to get VMStateDescription.  The previous commit made
that unnecessary.

Include migration/vmstate.h only where it's still needed.  Touching it
now recompiles only some 1600 objects.
