2d0d2837dc Support default block interfaces per QEMUMachine
There are QEMUMachines that have neither IF_IDE nor IF_SCSI as a
default/standard interface to their block devices / drives. Therefore,
this patch introduces a new field default_block_type per QEMUMachine
struct. The prior use_scsi field becomes thereby obsolete and is
replaced through .default_block_type = IF_SCSI.

This patch also changes the default for s390x to IF_VIRTIO and
removes an early hack that converts IF_IDE drives.
Other parties have already claimed interest (e.g. IF_SD for exynos)

To create a sane default, for machines that dont specify a
default_block_type, this patch makes IF_IDE = 0 and IF_NONE = 1.
I checked all users of IF_NONE (blockdev.c and ww/device-hotplug.c)
as well as IF_IDE and it seems that it is ok to change the defines -
in other words, I found no obvious (to me) assumption in the code
regarding IF_NONE==0. IF_NONE is only set if there is an
explicit if=none. Without if=* the interface becomes IF_DEFAULT.

I would suggest to have some additional care, e.g. by letting
this patch sit some days in the block tree.

Based on an initial patch from Einar Lueck <elelueck@de.ibm.com>

a8170e5e97 Rename target_phys_addr_t to hwaddr
target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are
reserved) and its purpose doesn't match the name (most target_phys_addr_t
addresses are not target specific).  Replace it with a finger-friendly,
standards conformant hwaddr.

Outstanding patchsets can be fixed up with the command

  git rebase -i --exec 'find -name "*.[ch]"
                        | xargs s/target_phys_addr_t/hwaddr/g' origin

5f072e1f30 create struct for machine initialization arguments
This should help us to:
- More easily add or remove machine initialization arguments without
  having to change every single machine init function;
- More easily make mechanical changes involving the machine init
  functions in the future;
- Let machine initialization forward the init arguments to other
  functions more easily.

This change was half-mechanical process: first the struct was added with
the local ram_size, boot_device, kernel_*, initrd_*, and cpu_model local
variable initialization to all functions. Then the compiler helped me
locate the local variables that are unused, so they could be removed.

661bafb3e1 Versatile Express: Fix NOR flash 0 address and remove flash alias
In the A series memory map (implemented in the Cortex A15 CoreTile), the
first NOR flash bank (flash 0) is mapped to address 0x08000000, while
address 0x00000000 can be configured as alias to either the first or the
second flash bank. This patch fixes the definition of flash 0 address,
and for simplicity removes the alias definition.

25d7169982 hw/vexpress.c: Allow >4GB of RAM for Cortex-A15 daughterboard
Now that we have LPAE support and can handle passing 64 bit
RAM sizes to Linux via the device tree, we can lift the
restriction in the Versatile Express A15 daughterboard model
on not having more than 2GB of RAM. Allow up to 30GB, which
is the maximum that can fit in the address map before running
into the (unmodelled) aliases of the first 2GB.

96eacf6413 arm_boot: Pass base address of GIC CPU interface, not whole GIC
The arm_boot secondary boot loader code needs the address of
the GIC CPU interface. Obtaining this from the base address
of the private peripheral region was possible for A9 and 11MPcore,
but the A15 puts the GIC CPU interface in a different place.
So make boards pass in the GIC CPU interface address directly.

b720687868 hw/vexpress.c: Instantiate the motherboard CLCD
Instantiate the CLCD on the vexpress motherboard as well as one on
the daughterboard -- the A15 daughterboard does not have a CLCD
and so relies on the motherboard one.

At the moment QEMU doesn't provide infrastructure for selecting
which display device gets to actually show graphics -- the first
one registered is it. Fortunately this works for the major use
case (Linux): if the daughterboard has a CLCD it will come first
and be used, otherwise we fall back to the motherboard CLCD.
So we don't (currently) need to implement the control register
which allows software to tell the mux which video output to pass
through to the outside world.

aac1e02c1d hw/vexpress.c: Move secondary CPU boot code to SRAM
On real Versatile Express hardware, the boot ROM puts the secondary
CPU bootcode/holding pen in SRAM. We can therefore rely on Linux not
trashing this memory until secondary CPUs have booted up, and can
put our QEMU-specific pen code in the same place. This allows us to
drop the odd "hack" RAM page we were using before.

c5705a7728 vmstate, memory: decouple vmstate from memory API
Currently creating a memory region automatically registers it for
live migration.  This differs from other state (which is enumerated
in a VMStateDescription structure) and ties the live migration code
into the memory core.

Decouple the two by introducing a separate API, vmstate_register_ram(),
for registering a RAM block for migration.  Currently the same
implementation is reused, but later it can be moved into a separate list,
and registrations can be moved to VMStateDescription blocks.
