The Xilinx ZynqMP SoC and EP108 board supports three memory regions:
- A 2GB region starting at 0
- A 32GB region starting at 32GB
- A 256GB region starting at 768GB
This patch adds support for the first two memory regions, which is
automatically created based on the size specified by the QEMU memory
command line argument.
On hardware the physical memory region is one continuous region, it is then
mapped into the three different regions by the DDRC. As we don't model the
DDRC this is done at startup by QEMU. The board creates the memory region and
then passes that memory region to the SoC. The SoC then maps the memory
regions.

For ARM we have a little minimalist bootloader in hw/arm/boot.c which
takes the place of firmware if we're directly booting a Linux kernel.
Unfortunately a few devices need special case handling in this situation
to do the initialization which on real hardware would be done by
firmware. (In particular if we're booting a kernel in NonSecure state
then we need to make a TZ-aware GIC put all its interrupts into Group 1,
or the guest will be unable to use them.)
Create a new QOM interface which can be implemented by devices which
need to do something different from their default reset behaviour.
The callback will be called after machine initialization and before
first reset.

Including qemu-common.h from other header files is generally a bad
idea, because it means it's very easy to end up with a circular
dependency. For instance, if we wanted to include memory.h from
qom/cpu.h we'd end up with this loop:
memory.h -> qemu-common.h -> cpu.h -> cpu-qom.h -> qom/cpu.h -> memory.h
Remove the include from memory.h. This requires us to fix up a few
other files which were inadvertently getting declarations indirectly
through memory.h.
The biggest change is splitting the fprintf_function typedef out
into its own header so other headers can get at it without having
to include qemu-common.h.

Introduce the new boolean field "arm_boot_info.firmware_loaded". When this
field is set, it means that the portion of guest DRAM that the VCPU
normally starts to execute, or the pflash chip that the VCPU normally
starts to execute, has been populated by board-specific code with
full-fledged guest firmware code, before the board calls
arm_load_kernel().
Simultaneously, "arm_boot_info.firmware_loaded" guarantees that the board
code has set up the global firmware config instance, for arm_load_kernel()
to find with fw_cfg_find().
Guest kernel (-kernel) and guest firmware (-bios, -pflash) has always been
possible to specify independently on the command line. The following cases
should be considered:
nr -bios -pflash -kernel description
unit#0
-- ------- ------- ------- -------------------------------------------
1 present present absent Board code rejects this case, -bios and
present present present -pflash unit#0 are exclusive. Left intact

2 absent absent present Traditional kernel loading, with qemu's
minimal board firmware. Left intact by this
patch.
3 absent present absent Preexistent case for booting guest firmware
present absent absent loaded with -bios or -pflash. Left intact

4 absent absent absent Preexistent case for not loading any
firmware or kernel up-front. Left intact by

5 present absent present New case introduced by this patch: kernel
absent present present image is passed to externally loaded
firmware in unmodified form, using fw_cfg.
An easy way to see that this patch doesn't interfere with existing cases
is to realize that "info->firmware_loaded" is constant zero at this point.
Which makes the "outer" condition unchanged, and the "inner" condition
(with the fw_cfg-related code) dead.

Adds the secure_boot boolean field to the arm_boot_info descriptor. This
fields is used to indicate whether Linux should boot into secure or non-secure
state if the ARM EL3 feature is enabled. The default is to leave the CPU in an
unaltered reset state. On EL3 enabled systems, the reset state is secure and
can be overridden by setting the added field to false.

Device models should access their block backends only through the
block-backend.h API. Convert them, and drop direct includes of
inappropriate headers.
Just four uses of BlockDriverState are left:
* The Xen paravirtual block device backend (xen_disk.c) opens images
itself when set up via xenbus, bypassing blockdev.c. I figure it
should go through qmp_blockdev_add() instead.
* Device model "usb-storage" prompts for keys. No other device model
does, and this one probably shouldn't do it, either.
* ide_issue_trim_cb() uses bdrv_aio_discard() instead of
blk_aio_discard() because it fishes its backend out of a BlockAIOCB,
which has only the BlockDriverState.
* PC87312State has an unused BlockDriverState[] member.
The next two commits take care of the latter two.

This argument is a MemoryRegion and not an AddressSpace.
"Address space" means something quite different to "memory region"
in QEMU parlance so rename the variable to reduce confusion.

The row and column values use only a very limited range (-1 ... 7),
so a byte value is sufficient.

Add a callback hook in arm_boot_info to allow board models to
modify the device tree blob if they need to. (The major expected
use case is to add virtio-mmio nodes for virtio-mmio transports
that exist in QEMU but not in the hardware.)

Many of these should be cleaned up with proper qdev-/QOM-ification.
Right now there are many catch-all headers in include/hw/ARCH depending
on cpu.h, and this makes it necessary to compile these files per-target.
However, fixing this does not belong in these patches.
