[PATCH] meta-agl-jailhouse: Add support for virtio over IVSHMEM block

This patch adds the support for the virtio over IVSHMEM block for AGL with Jailhouse.

Current state of the Patchset:
- Add PCI devices from (00:0c.0 - 00:0f.0), for various virtio devices(virtio-ivshmem-{block, console, NET, custom}), primarily for virtio-blk.
- Add Common memory regions for virtio-blk in the Root-Cell and Non-Root-Linux-Cell configurations.
- Add Documentation `meta-agl-jailhouse.md` for usage and Instructions.
- Add `virtio-ivshmem-block` and `virtio-ivshmem-console` recipes for ott Kernel modules.

v2 (Anmol): Update `agl-linux-x86-demo.c` and `qemu-agl.c` for PCI macros and small descriptions for IVSHMEM PCI devices.
V3 (Anmol): 
           - [RFC] Add packagegroup for the virtio-ivshmem-{block, console} applications.
           - Update the `meta-agl-jailhouse.md` for architecture specific information.
v4 (Anmol): Update recipe files according to the new syntax(3.4-honister).
v5 (Anmol): 
           - Update recipe files for virtio-ivshmem binaries.
           - Update `50_local.conf.inc` for `packagegroup-agl-jailhouse`.
v5 (Anmol): Update syntax for `50_local.conf.inc`.

+## Jailhouse support layer
+
+
+Yocto layer that enables the use of the Jailhouse partitioning hypervisor - <https://github.com/siemens/jailhouse>.
+
+### How to Enable and Use
+
+### For QEmu x86_64
+
+> Note: Right now the below setup is only working for Intel Machines.
+
+The AGL feature `agl-jailhouse` has to be enabled. That needs to be done when including aglsetup.sh, for example:
+
+```sh
+$ source meta-agl/scripts/aglsetup.sh -m qemux86-64 -b build agl-devel agl-jailhouse
+```
+
+That will enable this layer and include the `jailhouse` package in the image.
+
+
+Then, in the target system, the cell configurations (*.cell) are placed in `/usr/share/jailhouse/cells/` and the demo inmates (bare-metal applications to run in a non-root cell) are located in `/usr/share/jailhouse/inmates`.
+
+
+After that follow the [AGL-Documentation](https://docs.automotivelinux.org/en/master/#0_Getting_Started/2_Building_AGL_Image/2_Downloading_AGL_Software/) as usual and build the image using `bitbake core-image-minimal`.
+
+
+After successfully building the image we need to QEmulate the Image using `runqemu`:
+
+
+```sh
+
+$ runqemu qemux86-64 slirp kvm publicvnc serial bootparams="verbose ipv6.disable=1 intel_iommu=off"
+
+```
+
+After successful emulation of the Image, you will see something similar to this:
+
+
+```sh
+
+[ 0.021231] [Firmware Bug]: TSC_DEADLINE disabled due to Errata; please update microcode to version: 0xb2 (or later)
+
+[ 0.588075] kvm: already loaded the other module
+
+[ 0.926525] hdaudio hdaudioC0D0: Unable to bind the codec
+
+Automotive Grade Linux 11.91.0 qemux86-64 ttyS0
+
+qemux86-64 login: root
+
+```
+
+### For Running the Linux Cell
+
+
+In order to spin-up the Root cell and Inmates, you will need Cell Configurations (*.cell) and Inmates, which you will find at `/usr/share/jailhouse/cell` and `/usr/share/jailhouse/inmates`.
+
+
+But for Linux-Cell some preparation is needed and the things which you will require include:
+
+
+- `bzImage`
+
+- `rootfs.cpio`
+
+
+These files you can find easily in the `build/tmp/deploy/images/qemux86-64/`.
+
+After obtaining these files you have to `scp` these to the emulated Image.
+
+Now you should have everything in the target system and you can now spin up the things but before that check, if `jailhouse` is present or not:
+
+```sh
+
+qemux86-64:~# lsmod
+
+Module Size Used by
+
+jailhouse 36864 0
+
+```
+As you can see it’s showing present, In case if it’s not present then run `modprobe jailhouse`, it will load the Jailhouse kernel module.
+
+After loading the module now we have to enable the Jailhouse-Root-Cell, enable this by the below command:
+
+```sh
+
+qemux86-64:~# jailhouse enable /usr/share/jailhouse/cells/qemu-agl.cell
+
+```
+
+ And check the console for the logs.
+
+After loading jailhouse Root-cell, now we have to load the Non-root Linux cell, so for that run the below commands:
+
+
+```sh
+
+qemux86-64:~# jailhouse cell linux /usr/share/jailhouse/cells/agl-linux-x86-demo.cell bzImage -i rootfs.cpio -w out.file -c "console=ttyS2,115200 earlycon earlyprintk"
+
+```
+
+
+> Note: In the above command, when you add the `-w out.file` option then it will spit out some commands to start the non-root cell, if not then the cell will boot as usual. Those spitted out commands would look something like these below, you have to run it one by one:
+
+
+
+```sh
+
+qemux86-64:~# jailhouse cell create /usr/share/jailhouse/cells/agl-linux-x86-demo.cell
+
+qemux86-64:~# jailhouse cell load linux-x86-demo linux-loader.bin -a 0x0 bzImage -a 0xffc600 rootfs.cpio -a 0x3d89000 out.file -a 0x1000
+
+qemux86-64:~# jailhouse cell start linux-x86-demo.cell
+
+```
+
+> Note: As you can see in the spit-out commands there is a `linux-loader.bin` is present, this is a tiny bootloader that is required to boot the Linux-inmate or Linux-non-root cell. It is located in `/usr/libexec/jailhouse/linux-loader.bin` in the Emulated Image.
+
+After running the above commands you will see that Linux is booting in another console.
+
+Some helper scripts are present to automate all this, and it can be found [here](https://gerrit.automotivelinux.org/gerrit/gitweb?p=AGL/meta-agl-devel.git;a=tree;f=meta-agl-jailhouse/recipes-extended/jailhouse/files/helper-scripts).
+
+
+### For Testing Virtio over IVSHMEM Block
+
+You can test the Virtio-block over IVSHMEM by following the steps below:
+
+**This is for the Root-cell <---> Non-Root-Cell communication.**
+
+First, you have to boot the Image and enable the `qemu-agl.cell` into the target system, as described in the above sections.
+
+After that follow the below steps to get it spinning:
+
+```sh
+
+qemux86-64:~# jailhouse enable /usr/share/jailhouse/cells/qemu-agl.cell
+qemux86-64:~# modprobe uio_ivshmem
+
+```
+
+After this check for the PCI device using `lspci -k`, you will see something like this below:
+
+```sh
+
+qemux86-64:~# lspci -k
+
+.
+
+.
+
+.
+
+00:0c.0 Unassigned class [ff80]: Siemens AG Device 4106
+
+Subsystem: Siemens AG Device 4106
+
+.
+
+.
+
+.
+
+```
+
+After confirming, run the below command, this will create a virtio block backend
+
+```sh
+
+qemux86-64:~# echo "110a 4106 110a 4106 ffc002 ffffff" >
+
+/sys/bus/pci/drivers/uio_ivshmem/new_id
+
+```
+
+And after that, start the backend service like this:
+
+```sh
+
+qemux86-64:~# ./virtio-ivshmem-block /dev/uio0 disk.img
+
+Waiting for peer to be ready...
+
+```
+
+After running the backend-service boot or reboot another cell, and backend will show something like this:
+
+```sh
+
+qemux86-64:~ # ./virtio-ivshmem-block /dev/uio0 disk.img
+
+Waiting for peer to be ready...
+
+Starting virtio device
+
+device_status: 0x0
+
+device_status: 0x1
+
+device_status: 0x3
+
+device_features_sel: 1
+
+device_features_sel: 0
+
+.
+
+.
+
+.
+
+```
+
+In the Non-Root-Linux, the disk will show up as /dev/vda and can be accessed normally.
+
+
+>Note:
+>- For the `virtio-ivshmem-block` you can find it in target system at `/usr/bin/`, if not then copy it from here `build/tmp/work-shared/qemux86-64/kernel-source/tools/virtio/virtio-ivshmem-block`.
+>
+>- For the `disk.img`, It needs to be a raw image. But its size matters as that defines the virtual disk size, but you may even leave it empty and only partition or format it from the front-end guest.
+>
+> e.g:
+> 
+> $ dd if=/dev/zero of=disk.img bs=1M count=1024
+> 
+> $ mkfs.ext4 disk.img
