This series removes ad hoc RAM allocation API (memory_region_allocate_system_memory)
and consolidates it around hostmem backend. It allows to
* resolve conflicts between global -mem-prealloc and hostmem's "policy" option,
fixing premature allocation before binding policy is applied
* simplify complicated memory allocation routines which had to deal with 2 ways
to allocate RAM.
* reuse hostmem backends of a choice for main RAM without adding extra CLI
options to duplicate hostmem features. A recent case was -mem-shared, to
enable vhost-user on targets that don't support hostmem backends [1] (ex: s390)
* move RAM allocation from individual boards into generic machine code and
provide them with prepared MemoryRegion.
* clean up deprecated NUMA features which were tied to the old API (see patches)
- "numa: remove deprecated -mem-path fallback to anonymous RAM"
- (POSTPONED, waiting on libvirt side) "forbid '-numa node,mem' for 5.0 and newer machine types"
- (POSTPONED) "numa: remove deprecated implicit RAM distribution between nodes"
Introduce a new machine.memory-backend property and wrapper code that aliases
global -mem-path and -mem-alloc into automatically created hostmem backend
properties (provided memory-backend was not set explicitly given by user).
A bulk of trivial patches then follow to incrementally convert individual
boards to using machine.memory-backend provided MemoryRegion.
Board conversion typically involves:
* providing MachineClass::default_ram_size and MachineClass::default_ram_id
so generic code could create default backend if user didn't explicitly provide
memory-backend or -m options
* dropping memory_region_allocate_system_memory() call
* using convenience MachineState::ram MemoryRegion, which points to MemoryRegion
allocated by ram-memdev
On top of that for some boards:
* missing ram_size checks are added (typically it were boards with fixed ram size)
* ram_size fixups are replaced by checks and hard errors, forcing user to
provide correct "-m" values instead of ignoring it and continuing running.
After all boards are converted, the old API is removed and memory allocation
routines are cleaned up.
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.

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 region in range [0xf0000000 - 0xf1000000] is the PDC area
(Processor Dependent Code), where the firmware is loaded.
This region has higher priority than the main memory.
When the machine has more than 3840MB of RAM, there is an
overlap. Since the PDC is closer to the CPU in the bus
hierarchy, it gets accessed first, and the CPU does not have
access to the RAM in this range.
To model the same behavior and keep a simple memory layout,
reduce the priority of the RAM region. The PDC region ends
overlapping the RAM.

The hardware expects DIMM slots of 1 or 2 GB, allowing up to
4 GB of memory. We want to accept the same amount of memory the
hardware can deal with. DIMMs of 768MB are not available.
However we have to deal with a firmware limitation: currently
SeaBIOS only supports 32-bit, and expects the RAM size in a
32-bit register. When using a 4GB configuration, the 32-bit
register get truncated and we report a size of 0MB to SeaBIOS,
which ends halting the machine:
$ qemu-system-hppa -m 4g -serial stdio
SeaBIOS: Machine configured with too little memory (0 MB), minimum is 16 MB.
SeaBIOS wants SYSTEM HALT.
The easiest way is to restrict the machine to 3GB of memory.

virtio-gpu would be preferrable. At least for now, only enable

greater than the DINO_HPA of 0xfff80000.

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.

Previously, if the size of initrd >=2G, qemu exits with error:
root@haswell-OptiPlex-9020:/home/lizj# /home/lizhijian/lkp/qemu-colo/x86_64-softmmu/qemu-system-x86_64 -kernel ./vmlinuz-4.16.0-rc4 -initrd large.cgz -nographic
qemu: error reading initrd large.cgz: No such file or directory
root@haswell-OptiPlex-9020:/home/lizj# du -sh large.cgz
2.5G large.cgz
this patch changes the caller side that use this function to calculate
size of initrd file as well.

As part of commits a64aa5785d "hw: Deprecate -drive if=scsi with non-onboard
HBAs" and b891538e81 "hw/ppc/prep: Fix implicit creation of "-drive if=scsi"
devices" the lsi53c895a_create() and lsi53c810_create() functions were added
to wrap pci_create_simple() and scsi_bus_legacy_handle_cmdline().
Unfortunately this prevents us from changing qdev properties on the device
and/or changing the PCI configuration. By switching over to using the new
lsi53c8xx_handle_legacy_cmdline() function then the caller can now configure
and realize the LSI SCSI device exactly as required.
