spd_data_generate() can pass @errp to error_setg() more than once when
it adjusts both memory size and type. Harmless, because no caller
passes anything that needs adjusting. Until the previous commit,
sam460ex passed types that needed adjusting, but not sizes.
spd_data_generate()'s contract is rather awkward:
If everything's fine, return non-null and don't set an error.
Else, if memory size or type need adjusting, return non-null and
set an error describing the adjustment.
Else, return null and set an error reporting why no data can be
generated.
Its callers treat the error as a warning even when null is returned.
They don't create the "smbus-eeprom" device then. Suspicious.
Since the previous commit, only "everything's fine" can actually
happen. Drop the unused code and simplify the callers. This gets rid
of the error API violation.

While loading the executable, some platforms (like AVR) need to
detect CPU type that executable is built for - and, with this patch,
this is enabled by reading the field 'e_flags' of the ELF header of
the executable in question. The change expands functionality of
the following functions:
- load_elf()
- load_elf_as()
- load_elf_ram()
- load_elf_ram_sym()
The argument added to these functions is called 'pflags' and is of
type 'uint32_t*' (that matches 'pointer to 'elf_word'', 'elf_word'
being the type of the field 'e_flags', in both 32-bit and 64-bit
variants of ELF header). Callers are allowed to pass NULL as that
argument, and in such case no lookup to the field 'e_flags' will
happen, and no information will be returned, of course.

The Chardev events are listed in the QEMUChrEvent enum.
By using the enum in the IOEventHandler typedef we:
- make the IOEventHandler type more explicit (this handler
process out-of-band information, while the IOReadHandler
is in-band),
- help static code analyzers.
This patch was produced with the following spatch script:
@match@
expression backend, opaque, context, set_open;
identifier fd_can_read, fd_read, fd_event, be_change;
@@
qemu_chr_fe_set_handlers(backend, fd_can_read, fd_read, fd_event,

static
-void fd_event(void *opaque, int event)
+void fd_event(void *opaque, QEMUChrEvent event)

}
Then the typedef was modified manually in

Link property is the correct way to pass a MemoryRegion to a device
for DMA purposes.
Sidenote: as a sysbus device, this remains non-usercreatable
even though we can drop the specific flag here.

Register the memory region with sysbus_init_mmio() and look it up with
sysbus_mmio_get_region() to avoid accessing internal device fields.

sysbus devices should use the associated helper function instead of
calling memory_region_add_subregion() manually. This simplifies
slightly the code.

The function is specific to mipssim, let's inline it.
(when inlining, we use a DeviceState variable instead of SerialIO, as
it is the most common type used, and avoids having too many casts)

Memory mapped serial device is in fact a sysbus device. The following
patches will make use of sysbus facilities for resource and
registration. In particular, "serial-mm: use sysbus facilities" will
move internal serial realization to serial_mm_realize callback to
follow qdev best practices.

Remove the need to include i386/pc.h to get to the i8259 functions.
This is enough to remove the inclusion of hw/i386/pc.h from all non-x86
files.

The r4k machine was introduced in 2005 (6af0bf9c7) and its last
logical change was in 2005 (9542611a6). After that, one can
count 164 maintenance commits (QEMU API changes) with the
exception of 1 fix in 2015 (memory leak, commit 3ad9fd5a).
This machine was introduced as a proof of concept to run a MIPS
CPU. Two years later, the Malta machine was added (commit
5856de80), modeling a real platform.
Note also this machine has no specification except 5 lines in
the header of this file:
* emulates a simple machine with ISA-like bus.
* ISA IO space mapped to the 0x14000000 (PHYS) and
* ISA memory at the 0x10000000 (PHYS, 16Mb in size).
* All peripherial devices are attached to this "bus" with
* the standard PC ISA addresses.
The Linux kernel support for this machine has been dropped more
than 10 years ago in commit 302922e5.
It is time to deprecate this obsolete machine. Users are
recommended to use the Malta board, and its hardware is well
documented.

The script checkpatch.pl located in scripts folder was
used to detect all errors and warrnings in file:
hw/mips/mips_r4k.c
This mips r4000 machine file was edited and
all the errors and warrings generated by the checkpatch.pl
script were corrected and then the script was
ran again to make sure there are no more errors and warnings.
