Description
----------
Add a new class and unittest for generating FIT blobs.
Testing
-------
1. linux-yocto_5.4.bbappend was modified to have the following
configuration:
```
inherit fit-image
KERNEL_IMAGE_NODE[name] = "kernel"
KERNEL_IMAGE_NODE[description] = "${PF}"
KERNEL_IMAGE_NODE[data] = '/incbin/("./arch/${ARCH}/boot/zImage")'
KERNEL_IMAGE_NODE[type] = "kernel"
KERNEL_IMAGE_NODE[arch] = "${ARCH}"
KERNEL_IMAGE_NODE[os] = "linux"
KERNEL_IMAGE_NODE[compression] = "none"
KERNEL_IMAGE_NODE[load] = "${UBOOT_LOADADDRESS}"
KERNEL_IMAGE_NODE[entry] = "${UBOOT_ENTRYPOINT}"
KERNEL_IMAGE_NODE[hash] = "sha256"
FDT_IMAGE_NODE[name] = "fdt"
FDT_IMAGE_NODE[description] = "FDT blob"
FDT_IMAGE_NODE[data] = '/incbin/("./arch/${ARCH}/boot/dts/am335x-bone.dtb")'
FDT_IMAGE_NODE[type] = "flat_dt"
FDT_IMAGE_NODE[arch] = "${ARCH}"
FDT_IMAGE_NODE[compression] = "none"
FDT_IMAGE_NODE[hash] = "sha256"
CONF1_CONF_NODE[name] = "conf"
CONF1_CONF_NODE[description] = "Linux kernel and FDT blob"
CONF1_CONF_NODE[kernel] = "kernel"
CONF1_CONF_NODE[fdt] = "fdt"
FIT_IMAGES_NODE = "KERNEL_IMAGE_NODE FDT_IMAGE_NODE"
FIT_CONFIGURATIONS_NODE = "CONF1_CONF_NODE"
FIT_CONFIGURATIONS_NODE[default] = "${@d.getVarFlag('CONF1_CONF_NODE',
'name') or ""}"
```
2. Build the kernel: `bitbake virtual/kernel`
3. Verify that `image-fit.itb` is present in the build directory: PASS
4. Disassemble the image using the command: `dtc -I dtb -O dts
image-fit.itb`
5. Verify that the FIT source contains the expected configuration: PASS
6. Run the unittest using the command: `oe-selftest --run-tests
fit_image.FitImage`
7. Verify that is successfully: PASS
```

```
Changes since v1:
----------------
- Change the format of short-log to "<target>: <summary>"
Changes since v2:
----------------
- rename the file from `fit-image` to `fit_image` to successfully export
the class functions.
- adding new sanity checks.
- add missing dependency.
- fix a variable reference in a debug log.
Changes since v3:
----------------
- unit-test added
- class updated to support also properties for U-Boot image
Nandor Han (3):
Add a recipe for `python3-fdt` package
classes: Add a new bbclass that abstracts the generation of FIT blobs
selftest: add a unit-test for fit-image bbclass
