In order to revoke SRKs in platforms with AHAB we need to set a mask
during the signing/encryption process.
Create new TRUSTFENCE_SRK_REVOKE_MASK variable to export the
SRK_REVOKE_MASK variable required by the imx-boot signing script.
The revoke mask is not necessary for signing/encryption of other artifacts,
so set it by default to 0x0.

Environment encryption is not yet supported in U-Boot.
Unset TRUSTFENCE_ENCRYPT_ENVIRONMENT on the machine configuration
and remove the platform conditional on the class.

Rename recipe and fix the path of the progress binary. Also on the
rocko branch of meta-swupdate several signing mechanisms are
supported, and the value is used as a string to determine which one
to use.

- Trying to set the complete SWU packages signature key in the
TrustFence class was causing a build error when keys were not
yet generated. To avoid this, set only the key wildcard in the
TrustFence class and expand the variable in the SWU packages
recipes, when keys already exist.

- Enabled signing support while generating the swupdate
packages for 'core-image-base' and 'dey-image-qt'. The
signing support is only enabled when 'TUSTFENCE_SIGN=1'
and requires the recipe to set the private key that will
be used to generate the signature.
- Enabled hash support while generating the swupdate
packages for 'core-image-base' and 'dey-image-qt'. The
hash support requires the sw-description files to include
a new line for each image and/or file that will be added
to the update package. The hash is automatically calculated
and replaced in the sw-description files.

When encryption is enabled, the signed U-Boot image will be used for the uSD.
This allows the uSD image to boot the device and recover it from the U-Boot
console, which is its main purpose. Nevertheless, the uSD image will not be
able to boot Linux.

This reverts commit 2e13e194d9.
Currently we don't support booting encrypted images from an SDCARD, so
just disable the generation of such images.

By default, on closed devices you cannot revoke any key. To do so, it is
required to compile a U-Boot which instructs the HAB not to set the sticky
bit which write protects that field in the OCOTP controller.
This patch introduces a Yocto macro which allows to configure U-Boot in
that way.
In the ConnectCore 6, the value of this settings is ignored, because HAB never
sets the sticky bit which write protects that field.

While performing usability testing on the TrustFence documentation, it has
been noted that in order to follow the secure boot instructions the
console needs to be enabled.
We have now moved the secure console section to the end of the
documentation so that disabling the console is the last configuration to
make in a secure system.

When Trustfence is enabled, this adds a dependence on the TF initramfs,
so it's built and added to the boot image.
It also modifies the u-boot boot script on the fly, to boot correctly
using the Trustfence initramfs.

The TRUSTFENCE_UBOOT_DEK_SIZE Yocto macro maps to the UBOOT_DEK_SIZE U-Boot
Kconfig entry, which is defined as a choice entry. This makes necessary
to explicitly define the choice Kconfig entry for the configuration to
work.

There are several possible values for TRUSTFENCE_UBOOT_ENV_DEK:
* Not defined: if the trustfence support is not included.
Should not include the feature.
* 32 characters: when defining a valid key.
Should include the feature.
* "0": when explicitly disabling the feature.
Should not include the feature
* <other>: Invalid value, should trigger the error.
This commits fixes the logic so that 'None' (no defined) is taken as a valid
value.
