51cdb6806f Revert "Remove the unused sh4eb target"
This reverts commit 73ceb12960.

The "r2d" machine can work in big endian mode, see:

 https://lore.kernel.org/qemu-devel/d6755445-1060-48a8-82b6-2f392c21f9b9@landley.net/

So the reasoning for removing sh4eb was wrong.

f1826463d2 machine/nitro-enclave: New machine type for AWS Nitro Enclaves
AWS nitro enclaves[1] is an Amazon EC2[2] feature that allows creating
isolated execution environments, called enclaves, from Amazon EC2
instances which are used for processing highly sensitive data. Enclaves
have no persistent storage and no external networking. The enclave VMs
are based on the Firecracker microvm with a vhost-vsock device for
communication with the parent EC2 instance that spawned it and a Nitro
Secure Module (NSM) device for cryptographic attestation. The parent
instance VM always has CID 3 while the enclave VM gets a dynamic CID.

An EIF (Enclave Image Format)[3] file is used to boot an AWS nitro enclave
virtual machine. This commit adds support for AWS nitro enclave emulation
using a new machine type option '-M nitro-enclave'. This new machine type
is based on the 'microvm' machine type, similar to how real nitro enclave
VMs are based on Firecracker microvm. For nitro-enclave to boot from an
EIF file, the kernel and ramdisk(s) are extracted into a temporary kernel
and a temporary initrd file which are then hooked into the regular x86
boot mechanism along with the extracted cmdline. The EIF file path should
be provided using the '-kernel' QEMU option.

In QEMU, the vsock emulation for nitro enclave is added using vhost-user-
vsock as opposed to vhost-vsock. vhost-vsock doesn't support sibling VM
communication which is needed for nitro enclaves. So for the vsock
communication to CID 3 to work, another process that does the vsock
emulation in  userspace must be run, for example, vhost-device-vsock[4]
from rust-vmm, with necessary vsock communication support in another
guest VM with CID 3. Using vhost-user-vsock also enables the possibility
to implement some proxying support in the vhost-user-vsock daemon that
will forward all the packets to the host machine instead of CID 3 so
that users of nitro-enclave can run the necessary applications in their
host machine instead of running another whole VM with CID 3. The following
mandatory nitro-enclave machine option has been added related to the
vhost-user-vsock device.
  - 'vsock': The chardev id from the '-chardev' option for the
vhost-user-vsock device.

AWS Nitro Enclaves have built-in Nitro Secure Module (NSM) device which
has been added using the virtio-nsm device added in a previous commit.
In Nitro Enclaves, all the PCRs start in a known zero state and the first
16 PCRs are locked from boot and reserved. The PCR0, PCR1, PCR2 and PCR8
contain the SHA384 hashes related to the EIF file used to boot the VM
for validation. The following optional nitro-enclave machine options
have been added related to the NSM device.
  - 'id': Enclave identifier, reflected in the module-id of the NSM
device. If not provided, a default id will be set.
  - 'parent-role': Parent instance IAM role ARN, reflected in PCR3
of the NSM device.
  - 'parent-id': Parent instance identifier, reflected in PCR4 of the
NSM device.

73ceb12960 Remove the unused sh4eb target
Since the "shix" machine has been removed, the "r2d" machine is the only
machine that is still available for the sh4 and sh4eb targets. However,
the "r2d" machine apparently does not work in big endian mode, see here:

 https://lore.kernel.org/qemu-devel/87a5fwjjew.wl-ysato@users.sourceforge.jp/

So there is no working machine left in the sh4eb-softmmu target, i.e. it
is currently completely useless. Thus remove it from the configuration
now. (Note: The linux-user binary is not removed since it might still
be used to run sh4 binaries in big endian mode).

The Sharp XScale-based PDA board models akita, borzoi, spitz,

Remove the source files for the board models themselves, and their
documentation. There were no tests for these boards.

We will move the text describing the dropped boards from
deprecated.rst to removed-features.rst when we've cleaned up all the
boards it lists.  Device models used only by removed board models
will be removed in separate commits.

  The CRIS architecture was pulled from Linux in 4.17 and
  the compiler is no longer packaged in any distro making
  it harder to run the `check-tcg` tests. Unless we can
  improve the testing situation there is a chance the code
  will bitrot without anyone noticing.

With KVM virtualization, debug exception is injected to guest kernel
rather than host for normal break intruction. Here hypercall
instruction with special code is used for sw breakpoint usage,
and detailed instruction comes from kvm kernel with user API
KVM_REG_LOONGARCH_DEBUG_INST.

Now only software breakpoint is supported, and it is allowed to
insert/remove software breakpoint. We can debug guest kernel with gdb
method after kernel is loaded, hardware breakpoint will be added in later.

Those emulators will be skipped if libfdt is disabled, or if it
