Vishal ChourasiaandPhilippe Mathieu-Daudé a9c608904f hw/core/loader: capture Error from load_image_targphys
Add Error **errp parameter to load_image_targphys(),
load_image_targphys_as(), and get_image_size() to enable better
error reporting when image loading fails.

Pass NULL for errp in all existing call sites to maintain current
behavior. No functional change intended in this patch.

Philippe Mathieu-Daudé 18727804c0 hw/xtensa/xtfpga: Have xtfpga_init() only initialize MMU
cpu_reset() should not be used with an unrealized CPU.
Here we simply want to initialize the MMU, not the CPU,

Alexander GrafandPhilippe Mathieu-Daudé ff871d0462 hw/pci-host/gpex: Allow more than 4 legacy IRQs
Some boards such as vmapple don't do real legacy PCI IRQ swizzling.
Instead, they just keep allocating more board IRQ lines for each new
legacy IRQ. Let's support that mode by giving instantiators a new
"nr_irqs" property they can use to support more than 4 legacy IRQ lines.
In this mode, GPEX will export more IRQ lines, one for each device.

Bernhard BeschowandPaolo Bonzini 7e6b5497ea hw/char: Extract serial-mm
hw/char/serial currently contains the implementation of both TYPE_SERIAL and
TYPE_SERIAL_MM. According to serial_class_init(), TYPE_SERIAL is an internal
class while TYPE_SERIAL_MM is used by numerous machine types directly. Let's
move the latter into its own module which makes the dependencies more obvious
and the code more tidy.

The includes and the dependencies have been converted mechanically except in the
hw/char directories which were updated manually. The result was compile-tested.
Now, only hw/char makes direct use of TYPE_SERIAL:

  # grep -r -e "select SERIAL" | grep -v SERIAL_
  hw/char/Kconfig:    select SERIAL
  hw/char/Kconfig:    select SERIAL
  hw/char/Kconfig:    select SERIAL
  hw/char/Kconfig:    select SERIAL
  hw/char/Kconfig:    select SERIAL

  # grep -r -e "/serial\\.h"
  include/hw/char/serial-mm.h:#include "hw/char/serial.h"
  hw/char/serial-pci-multi.c:#include "hw/char/serial.h"
  hw/char/serial.c:#include "hw/char/serial.h"
  hw/char/serial-isa.c:#include "hw/char/serial.h"

Now that boards are enabled by default and the "CONFIG_FOO=y"
entries are gone from configs/devices/, there cannot be any more
a conflicts between the default contents of configs/devices/
and a failed "depends on" clause.

With this change, each individual board or target can express
whether it needs FDT.  It can then include the common code in the
build via "select DEVICE_TREE", which will also as tell meson to link
with libfdt.

This allows building non-microvm x86 emulators without having
libfdt available.

TARGET_BIG_ENDIAN is *always* defined, either as 0 for little endian
targets or as 1 for big endian targets. So we can use this as a value
directly in places that need such a 0 or 1 for some reason, instead
of taking a detour through an additional local variable or something
similar.

Markus Armbruster b21e238037 Use g_new() & friends where that makes obvious sense
g_new(T, n) is neater than g_malloc(sizeof(T) * n).  It's also safer,
for two reasons.  One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.

This commit only touches allocations with size arguments of the form
sizeof(T).
