89c43bdf20 arm/highbank: use memdev for RAM
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.

533eb415df arm/aspeed: actually check RAM size
It's supposed that SOC will check if "-m" provided
RAM size is valid by setting "ram-size" property and
then board would read back valid (possibly corrected
value) to map RAM MemoryReging with valid size.
It isn't doing so, since check is called only
indirectly from
  aspeed_sdmc_reset()->asc->compute_conf()
or much later when guest writes to configuration
register.

So depending on "-m" value QEMU end-ups with a warning
and an invalid MemoryRegion size allocated and mapped.
(examples:
 -M ast2500-evb -m 1M
    0000000080000000-000000017ffffffe (prio 0, i/o): aspeed-ram-container
      0000000080000000-00000000800fffff (prio 0, ram): ram
      0000000080100000-00000000bfffffff (prio 0, i/o): max_ram
 -M ast2500-evb -m 3G
    0000000080000000-000000017ffffffe (prio 0, i/o): aspeed-ram-container
      0000000080000000-000000013fffffff (prio 0, ram): ram
      [DETECTED OVERFLOW!] 0000000140000000-00000000bfffffff (prio 0, i/o): max_ram
)
On top of that sdmc falls back and reports to guest
"default" size, it thinks machine should have.

This patch makes ram-size check actually work and
changes behavior from a warning later on during
machine reset to error_fatal at the moment SOC.ram-size
is set so user will have to fix RAM size on CLI
to start machine.

It also gets out of the way mutable ram-size logic,
so we could consolidate RAM allocation logic around
pre-allocated hostmem backend (supplied by user or
auto created by generic machine code depending on
supplied -m/mem-path/mem-prealloc options.

6b61c2c596 initialize MachineState::ram in NUMA case
In case of NUMA there are 2 cases to consider:
 1. '-numa node,memdev', the only one that will be available
    for 5.0 and newer machine types.

    In this case reuse current behavior, with only difference
    memdevs are put into MachineState::ram container +
    a temporary glue to keep memory_region_allocate_system_memory()
    working until all boards converted.

 2. fake NUMA ("-numa node mem" and default RAM splitting)
    the later has been deprecated and will be removed but the former
    is going to stay available for compat reasons for 5.0 and
    older machine types

    it takes allocate_system_memory_nonnuma() path, like non-NUMA
    case and falls under conversion to memdev.  So extend non-NUMA
    MachineState::ram initialization introduced in previous patch
    to take care of fake NUMA case.

82b911aaff machine: introduce convenience MachineState::ram
the new field will be used by boards to get access to main
RAM memory region and will help to save boiler plate in
boards which often introduce a field or variable just for
this purpose.

Memory region will be equivalent to what currently used
memory_region_allocate_system_memory() is returning apart
from that it will come from hostmem backend.
Followup patches will incrementally switch boards to using
RAM from MachineState::ram.

Patch takes care of non-NUMA case and follow up patch will
initialize MachineState::ram for NUMA case.

Indeed the array should contain 13 entries, the undocumented
register 0x82c is missing. Fix by increasing the array size
and adding the missing register.

971b2a1e5b RISC-V Patches for the 5.0 Soft Freeze, Part 2
This is a fairly light-weight pull request, but I wanted to send it out to
 avoid the Goldfish stuff getting buried as the next PR should contain the H
 extension implementation.
 
 As far as this PR goes, it contains:
 
 * The addition of syscon device tree nodes for reboot and poweroff, which
   allows Linux to control QEMU without an additional driver.  The existing
   device was already compatible with the syscon interface.
 * A fix to our GDB stub to avoid confusing XLEN and FLEN, specifically useful
   for rv32id-based systems.
 * A device emulation for the Goldfish RTC device, a simple memory-mapped RTC.
 * The addition of the Goldfish RTC device to the RISC-V virt board.
 
 This passes "make check" and boots buildroot for me.

759f0f87e3 hw/arm/raspi: Extract the cores count from the board revision
The count of ARM cores is encoded in the board revision.  Add a
helper to extract the number of cores, and use it.  This will be
helpful when we add the Raspi0/1 that have a single core.

918c81a53e hw/arm/raspi: Use BCM2708 machine type with pre Device Tree kernels
When booting without device tree, the Linux kernels uses the $R1
register to determine the machine type. The list of values is
registered at [1].

There are two entries for the Raspberry Pi:

- https://www.arm.linux.org.uk/developer/machines/list.php?mid=3138
  name: MACH_TYPE_BCM2708
  value: 0xc42 (3138)
  status: Active, not mainlined
  date: 15 Oct 2010

- https://www.arm.linux.org.uk/developer/machines/list.php?mid=4828
  name: MACH_TYPE_BCM2835
  value: 4828
  status: Active, mainlined
  date: 6 Dec 2013

QEMU always used the non-mainlined type MACH_TYPE_BCM2708.
The value 0xc43 is registered to 'MX51_GGC' (processor i.MX51), and
0xc44 to 'Western Digital Sharespace NAS' (processor Marvell 88F5182).

The Raspberry Pi foundation bootloader only sets the BCM2708 machine
type, see [2] or [3]:

 133 9:
 134     mov r0, #0
 135     ldr r1, =3138       @ BCM2708 machine id
 136     ldr r2, atags       @ ATAGS
 137     bx  r4

U-Boot only uses MACH_TYPE_BCM2708 (see [4]):

 25 /*
 26  * 2835 is a SKU in a series for which the 2708 is the first or primary SoC,
 27  * so 2708 has historically been used rather than a dedicated 2835 ID.
 28  *
 29  * We don't define a machine type for bcm2709/bcm2836 since the RPi Foundation
 30  * chose to use someone else's previously registered machine ID (3139, MX51_GGC)
 31  * rather than obtaining a valid ID:-/
 32  *
 33  * For the bcm2837, hopefully a machine type is not needed, since everything
 34  * is DT.
 35  */

While the definition MACH_BCM2709 with value 0xc43 was introduced in
a commit described "Add 2709 platform for Raspberry Pi 2" out of the
mainline Linux kernel, it does not seem used, and the platform is
introduced with Device Tree support anyway (see [5] and [6]).

Remove the unused values (0xc43 introduced in commit 1df7d1f930
"raspi: add raspberry pi 2 machine" and 0xc44 in commit bade58166f
"raspi: Raspberry Pi 3 support"), keeping only MACH_TYPE_BCM2708.

b43bd40ba2 arm/acpi: simplify the description of PCI _CRS
The original code defines a named object for the resource template but
then returns the resource template object itself; the resulted output
is like below:

Method (_CRS, 0, NotSerialized)  // _CRS: Current Resource Settings
{
    Name (RBUF, ResourceTemplate ()
    {
        WordBusNumber (ResourceProducer, MinFixed, MaxFixed, PosDecode,
            0x0000,             // Granularity
            0x0000,             // Range Minimum
            0x00FF,             // Range Maximum
            0x0000,             // Translation Offset
            0x0100,             // Length
            ,, )
        ......
    })
    Return (ResourceTemplate ()
    {
        WordBusNumber (ResourceProducer, MinFixed, MaxFixed, PosDecode,
            0x0000,             // Granularity
            0x0000,             // Range Minimum
            0x00FF,             // Range Maximum
            0x0000,             // Translation Offset
            0x0100,             // Length
            ,, )
        ......
    })
}

So the named object "RBUF" is actually useless. The more natural way
is to return RBUF instead, or simply drop RBUF definition.

Choose the latter one to simplify the code.
