device tree blob name mismatch

The image downloaded from here:

doesn't boot in FVP Base EAM 4x4 model because bootloader is looking for fdt.dtb. There is no such file and boot fails.

After renaming fvp-base-gicv2-psci.dtb to fdt.dtb it is possible to boot without problems (checked on my local machine).

Unfortunately, I had to change UEFI so I could support multiple models with 1 UEFI binary and 1 default config.

Therefore, to run the AEMv8 or Cortex models you will need to use this extra step:

    ln -sf fvp-base-gicv2-psci.dtb fdt.dtb

To boot on the new Foundation FVP model you will need this step:

    ln -sf fvp-foundation-gicv2-psci.dtb fdt.dtb

The 13.11 release notes describe this, thankfully.

In order to boot FVP model using OE image LAVA changes are needed. Added lava-server to affected projects.

[Soumya Basak (soumya-basak)]

as per the instructions on comment #1

the the OE boot successful with FVP models.

Thank You.

A workaround to run the tests in LAVA:

     {
            "command": "boot_linaro_image",
            "parameters": {
                "boot_cmds": [
                    "sendline a",
                    "expect Choice:",
                    "sendline 2",
                    "expect Update entry:",
                    "sendline 1",
                    "expect File path of the EFI Application or the kernel: Image",
                    "sendline",
                    "expect Keep the local FDT: [y/n]",
                    "sendline n",
                    "expect Add an initrd: [y/n]",
                    "sendline n",
                    "expect Arguments to pass to the binary: console=ttyAMA0 earlyprintk=pl011,0x1c090000 debug user_debug=31 loglevel=9 root=/dev/vda2",
                    "sendline",
                    "expect Description for this new Entry: Linaro disk image on virtio",
                    "sendline",
                    "sendline 2",
                    "expect Update entry:",
                    "sendline 1",
                    "expect File path of the EFI Application or the kernel: Image",
                    "sendline",
                    "expect Add a local FDT: [y/n]",
                    "sendline y",
                    "expect File path of the local FDT:",
                    "sendline fvp-base-gicv2-psci.dtb",

Go with a regex for now. Need a longer term fix

Actually using regexes did't cut for this problem.
The configured binary name is only used to be able to get it out of the image, but is never passed explicitly to the models.
I am assuming the name `fdt.dtb` is hardcoded in the UEFI binary?

I have prepared and tested a workaround for this, which is up for review at
