On the vexpress-a9 board we try to map both RAM and flash to address 0,
as seen in "info mtree":
address-space: memory
0000000000000000-ffffffffffffffff (prio 0, i/o): system
0000000000000000-0000000003ffffff (prio 0, romd): alias vexpress.flashalias @vexpress.flash0 0000000000000000-0000000003ffffff
0000000000000000-0000000003ffffff (prio 0, ram): alias vexpress.lowmem @vexpress.highmem 0000000000000000-0000000003ffffff
0000000010000000-0000000010000fff (prio 0, i/o): arm-sysctl
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

In the vexpress board code, we allocate a new MemoryRegion at the top
of vexpress_common_init() but only set it up and use it inside the
"if (map[VE_NORFLASHALIAS] != -1)" conditional, so we leak it if not.
This isn't a very interesting leak as it's a tiny amount of memory
once at startup, but it's easy to fix.
We could silence Coverity simply by moving the g_new() into the
if() block, but this use of g_new(MemoryRegion, 1) is a legacy from
when this board model was originally written; we wouldn't do that
if we wrote it today. The MemoryRegions are conceptually a part of
the board and must not go away until the whole board is done with
(at the end of the simulation), so they belong in its state struct.
This machine already has a VexpressMachineState struct that extends
MachineState, so statically put the MemoryRegions in there instead of
dynamically allocating them separately at runtime.

drive_get_next() is basically a bad idea. It returns the "next" block
backend of a certain interface type. "Next" means bus=0,unit=N, where
subsequent calls count N up from zero, per interface type.
This lets you define unit numbers implicitly by execution order. If the
order changes, or new calls appear "in the middle", unit numbers change.
ABI break. Hard to spot in review.
The versatile and vexpress machines ("versatileab", "versatilepb",
"vexpress-a9", "vexpress-a15") connect just one or two backends of a
type with drive_get_next(). Change them to use drive_get() directly.
This makes the unit numbers explicit in the code.

When debugging QEMU it is often useful to put a breakpoint on the
error_setg_internal method impl.
Unfortunately the object_property_add / object_class_property_add
methods call object_property_find / object_class_property_find methods
to check if a property exists already before adding the new property.
As a result there are a huge number of calls to error_setg_internal
on startup of most QEMU commands, making it very painful to set a
breakpoint on this method.
Most callers of object_find_property and object_class_find_property,
however, pass in a NULL for the Error parameter. This simplifies the
methods to remove the Error parameter entirely, and then adds some
new wrapper methods that are able to raise an Error when needed.

[Conflicts in hw/misc/empty_slot.c and hw/sparc/leon3.c resolved]
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().

object_property_set_description() and

There are 85 calls of object_property_set_description() and

* 84 immediately follow the creation of the property.
* The one in spapr_rng_instance_init() refers to a property created in

Every one of them still gets to decide what to pass for @errp.
51 calls pass &error_abort, 32 calls pass NULL, one receives the error
and propagates it to &error_abort, and one propagates it to
&error_fatal. I'm actually surprised none of them violates the Error

What are we gaining by letting callers handle the "property not found"
error? Use when the property is not known to exist is simpler: you
don't have to guard the call with a check. We haven't found such a

flash.h's incomplete struct pflash_t is completed both in
pflash_cfi01.c and in pflash_cfi02.c. The complete types are
incompatible. This can hide type errors, such as passing a pflash_t
created with pflash_cfi02_register() to pflash_cfi01_get_memory().
Furthermore, POSIX reserves typedef names ending with _t.
Rename the two structs to PFlashCFI01 and PFlashCFI02.

Don't request that the arm_load_kernel() code should boot in secure
state if the CPU doesn't have a secure state. Currently this
doesn't make a difference because the boot.c code only examines
the secure_boot flag in code guarded by an ARM_FEATURE_EL3 check,
but upcoming changes for supporting booting into Hyp mode will
change that.

This adds the SiI9022 (and implicitly EDID I2C) device to the ARM
Versatile Express machine, and selects the two I2C devices necessary
in the arm-softmmu.mak configuration so everything will build
smoothly.
I am implementing proper handling of the graphics in the Linux
kernel and adding proper emulation of SiI9022 and EDID makes the
driver probe as nicely as before, retrieving the resolutions
supported by the "QEMU monitor" and overall just working nice.

Convert all the multi-line uses of fprintf(stderr, "warning:"..."\n"...
to use warn_report() instead. This helps standardise on a single
method of printing warnings to the user.
All of the warnings were changed using these commands:
find ./* -type f -exec sed -i \
'N; {s|fprintf(.*".*warning[,:] \(.*\)\\n"\(.*\));|warn_report("\1"\2);|Ig}' \
{} +
find ./* -type f -exec sed -i \
'N;N; {s|fprintf(.*".*warning[,:] \(.*\)\\n"\(.*\));|warn_report("\1"\2);|Ig}' \
{} +
find ./* -type f -exec sed -i \
'N;N;N; {s|fprintf(.*".*warning[,:] \(.*\)\\n"\(.*\));|warn_report("\1"\2);|Ig}' \
{} +
find ./* -type f -exec sed -i \
'N;N;N;N {s|fprintf(.*".*warning[,:] \(.*\)\\n"\(.*\));|warn_report("\1"\2);|Ig}' \

'N;N;N;N;N;N;N; {s|fprintf(.*".*warning[,:] \(.*\)\\n"\(.*\));|warn_report("\1"\2);|Ig}' \
{} +
Indentation fixed up manually afterwards.
Some of the lines were manually edited to reduce the line length to below
80 charecters. Some of the lines with newlines in the middle of the
string were also manually edit to avoid checkpatch errrors.
The #include lines were manually updated to allow the code to compile.
Several of the warning messages can be improved after this patch, to
keep this patch mechanical this has been moved into a later patch.

there are 2 use cases to deal with:
1: fixed CPU models per board/soc
2: boards with user configurable cpu_model and fallback to
default cpu_model if user hasn't specified one explicitly
For the 1st
drop intermediate cpu_model parsing and use const cpu type
directly, which replaces:
typename = object_class_get_name(
cpu_class_by_name(TYPE_ARM_CPU, cpu_model))
object_new(typename)
with
object_new(FOO_CPU_TYPE_NAME)
or
cpu_generic_init(BASE_CPU_TYPE, "my cpu model")
with
cpu_create(FOO_CPU_TYPE_NAME)
as result 1st use case doesn't have to invoke not necessary
translation and not needed code is removed.
For the 2nd
1: set default cpu type with MachineClass::default_cpu_type and
2: use generic cpu_model parsing that done before machine_init()
is run and:
2.1: drop custom cpu_model parsing where pattern is:
typename = object_class_get_name(
cpu_class_by_name(TYPE_ARM_CPU, cpu_model))
[parse_features(typename, cpu_model, &err) ]
2.2: or replace cpu_generic_init() which does what
2.1 does + create_cpu(typename) with just
create_cpu(machine->cpu_type)
as result cpu_name -> cpu_type translation is done using
generic machine code one including parsing optional features
if supported/present (removes a bunch of duplicated cpu_model
parsing code) and default cpu type is defined in an uniform way
within machine_class_init callbacks instead of adhoc places
in boadr's machine_init code.

Set the MachineClass flag ignore_memory_transaction_failures
for almost all ARM boards. This means they retain the legacy
behaviour that accesses to unimplemented addresses will RAZ/WI
rather than aborting, when a subsequent commit adds support
for external aborts.
The exceptions are:
* virt -- we know that guests won't try to prod devices
that we don't describe in the device tree or ACPI tables
* mps2 -- this board was written to use unimplemented-device
for all the ranges with devices we don't yet handle
New boards should not set the flag, but instead be written
like the mps2.
