Diaz de Grenu, Jose 6aff5b5524 trustfence: fix sign/encryption for very small artifacts
The HAB on the i.MX6/i.MX6UL expects an entrypoint which is used to pass
execution to U-Boot in the ROM code. In later executions of HAB, U-Boot calls
the HAB but ignores this value.

A fixed value of 0x1000 was being used for the entrypoint, which is too big for
really small artifacts, like bootscripts. This commit reduces the value to
0x100. This allows to sign and encrypt artifacts as small as 260 bytes.

Diaz de Grenu, Jose 5c4df1ddfd trustfence: add support for signing and encrypting DTBs and ramdisks
This patch introduces some parameters which allow to select the type of image
to be signed. Currently the supported types are:

* linux kernel (-l)
* DTB (-d)
* initramfs (-i)

This also moves the CONFIG_PLATFORM environment variable to a parameter, for
consistency.

Diaz de Grenu, Jose c5df62cd05 meta-digi-arm: trustfence-sign-tools: avoid using 'xxd'
When writing the fake IVT table in raw, rely on tac (part of the core-utils
package) instead of on xxd.

Diaz de Grenu, Jose c8ec33129d meta-digi-arm: trustfence-sign-tools: add sign tools recipe
Add a recipe to include all signing and encryption tools for U-Boot and
kernel images to the SDK. Move existing trustfence kernel scripts to this
new recipe.

This allows to use these scripts not only from the Yocto build system but
also as standalone tools for image signing and encryption.
