Currently, when BR2_TARGET_ARM_TRUSTED_FIRMWARE_UBOOT_AS_BL33 is
enabled, the arm-trusted-firmware package assumes that the BL33 image
provided by U-Boot is u-boot.bin. However for some platforms, the name
may be different (for example u-boot-dtb.bin). To support such use
cases, this commit adds a string option
BR2_TARGET_ARM_TRUSTED_FIRMWARE_UBOOT_BL33_IMAGE to configure the
U-Boot image name, which defaults to u-boot.bin to preserve backward
compatibility.

When the trusted firmware is built with debug support (DEBUG defined),
the generated images are located in a different path compared to a
build without debug support. The non debug images are located in
generated directory build/<platform>/release/ while the debug images
are located in generated directory build/<platform>/debug/.
This change introduces the boolean option
BR2_TARGET_ARM_TRUSTED_FIRMWARE_DEBUG to define whether the release or
debug configuration is used to build trusted firmware.
Note that enabling trusted firmware debug support using
BR2_TARGET_ARM_TRUSTED_FIRMWARE_ADDITIONAL_VARIABLES="... DEBUG=1 ..."
would not work since Buildroot will try to copy the generated files
from the wrong path.

This change allows one to build trusted firmware (TF-A) with OP-TEE as
BL32 secure payload.
When BR2_TARGET_ARM_TRUSTED_FIRMWARE_BL32_DEFAULT is enabled TF-A
builds a BL32 stage according the TF-A configuration directive. If
these specify no BL32 stage then TF-A will build without BL32
support. This is the default configuration and reflects TF-A legacy
integration in BR.
When BR2_TARGET_ARM_TRUSTED_FIRMWARE_BL32_OPTEE is enabled TF-A builds
with support for the OP-TEE OS as BL32.

configuration since release v1.5.
Change dependency on BR2_aarch64 into a dependency on either
BR2_ARM_CPU_ARMV8A/BR2_ARM_CPU_ARMV7A to better define
the target architectures supported by the package.
Set package configuration directive ARM_ARCH_MAJOR according to

directive ARCH based on BR2_aarch64/BR2_arm.

Some platforms (e.g Allwinner ARM64) don't build a FIP image out of
ATF, but only a BL31 image, which is then encapsulated in U-Boot. This
commit adds an ATF option to build such an image.

ATF can be used in different ways:
- ATF encapsulates U-Boot as the BL33, which is what is done on ARM
Juno (currently supported in Buildroot) and Marvell platforms (soon
to be supported)
- U-Boot encapsulates ATF's BL31, which is what is done on Allwinner
ARM64 platforms.
Until now we were assumming the former was always the case, but
obviously it isn't. Therefore, this patch adds an option that allows
to explicitly tell ATF that it encapsulates U-Boot as its BL33.
We adapt the only defconfig that uses ATF so that it enables this
option as appropriate.

Currently, our arm-trusted-firmware unconditionally builds a FIP
(Firmware Image Package). While this is often needed on platforms
where ATF encapsulates U-Boot, it is not the case on some other
platforms where it's U-Boot that encapsulates parts of ATF.
In order to prepare the support for the later platforms, we make
building the FIP image optional, and update the only defconfig we have
that uses ARM Trusted Firmware.
Note: we considered adding a "default y" here to preserve backward
compatibility, but there really isn't any default that is sane:
whether a FIP image needs to be built or not is purely platform
specific.

[Thomas:
- Rename the package from atfirmware to arm-trusted-firmware, in order
to match upstream.
- Remove option to apply custom patches. We no longer add such options,
and use the global patch directory instead.
- Rename the repo URL/version options, in order to not be Git specific,
in case support for fetching from other VCS is added later. This is
consistent with how other bootloaders handle this.
- Add license information.
- Do not add a weird dependency on the vexpress-firmware package in
Config.in. Instead, simply use it if it's available. Of course, some
configurations (such as the juno configuration) will fail to build if
vexpress-image is not enabled, but it's the responsibility of the
user to create a config that builds.
- Simplify misc aspects in the .mk file.]
