memory_region_allocate_system_memory() API is going away, so
replace it with memdev allocated MemoryRegion. The later is
initialized by generic code, so board only needs to opt in
to memdev scheme by providing
MachineClass::default_ram_id
and using MachineState::ram instead of manually initializing
RAM memory region.

If user provided non-sense RAM size, board will complain and
continue running with max RAM size supported or sometimes
crash like this:
%QEMU -M bamboo -m 1
exec.c:1926: find_ram_offset: Assertion `size != 0' failed.
Aborted (core dumped)
Also RAM is going to be allocated by generic code, so it won't be
possible for board to fix things up for user.
Make it error message and exit to force user fix CLI,
instead of accepting non-sense CLI values.
That also fixes crash issue, since wrongly calculated size
isn't used to allocate RAM

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.

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.

Our pflash devices are simplistically modelled has having
"num-blocks" sectors of equal size "sector-length". Real hardware
commonly has sectors of different sizes. How our "sector-length"
property is related to the physical device's multiple sector sizes
is unclear.
Helper functions pflash_cfi01_register() and pflash_cfi02_register()
create a pflash device, set properties including "sector-length" and
"num-blocks", and realize. They take parameters @size, @sector_len
and @nb_blocs.
QOMification left parameter @size unused. Obviously, @size should
match @sector_len and @nb_blocs, i.e. size == sector_len * nb_blocs.
All callers satisfy this.
Remove @nb_blocs and compute it from @size and @sector_len.

Machine "sam460ex" maps its flash memory at address 0xFFF00000. When
no image is supplied, its size is 1MiB (0x100000), and 512KiB of ROM
get mapped on top of its second half. Else, it's the size of the
image rounded up to the next multiple of 64KiB.
The rounding is actually useless: pflash_cfi01_realize() fails with
"failed to read the initial flash content" unless it's a no-op.
I have no idea what happens when the pflash's size exceeds 1MiB.
Useful outcomes seem unlikely.
I guess memory at the end of the address space remains unmapped when
it's smaller than 1MiB. Again, useful outcomes seem unlikely.
The physical hardware appears to have 512KiB of flash memory:
https://eu.mouser.com/datasheet/2/268/atmel_AT49BV040B-1180330.pdf
For now, just set the flash memory size to 1MiB regardless of image
size, and document the mess.

This patch adds an optional function pointer, 'elf_note_fn', to
load_elf() which causes load_elf() to additionally parse any
ELF program headers of type PT_NOTE and check to see if the ELF
Note is of the type specified by the 'translate_opaque' arg.
If a matching ELF Note is found then the specfied function pointer
is called to process the ELF note.
Passing a NULL function pointer results in ELF Notes being skipped.
The first consumer of this functionality is the PVHboot support
which needs to read the XEN_ELFNOTE_PHYS32_ENTRY ELF Note while
loading the uncompressed kernel binary in order to discover the
boot entry address for the x86/HVM direct boot ABI.

Fix the encoding of larger memory modules in the SoC registers which
allows specifying more than 1GB memory for sam460ex. Well, only 2GB
due to SoC and firmware restrictions which was the only missing value
compared to what the real hardware supports. The SoC should support up
to 4GB but when setting that the firmware hangs during memory test.
This may be an overflow bug in the firmware which I did not try to

noload kernels are loaded with the u-boot image header and as a result
the header size needs adding to the entry point. Fake up a hdr so the

The default location for the uboot file is 32MiB above bottom of DRAM.
This matches the recommendation in Documentation/arm/Booting.

exiting (within helper functions and macros). It handles two early error

We only emulate timer running at CPU frequency which is what most
guests expect so set the frequency to match real hardware. This also
allows setting clock multipliers which caused slowdown previously due
to wrong timer frequency.

Add emulation of aCube Sam460ex board based on AMCC 460EX embedded SoC.
This is not a complete implementation yet with a lot of components
still missing but enough for the U-Boot firmware to start and to boot
a Linux kernel or AROS.
