Sometimes, it may be desired that the DEY project does not sign the
artifacts, for example, if they are going to be externally signed on a
secure server. In this case, the user sets TRUSTFENCE_SIGN="0".
On STM platforms, all the variables were being set if TRUSTFENCE_SIGN="1"
and authentication support is not enabled on TF_A otherwise.
Set TF_A_SIGN_ENABLE (which adds authentication support to TF_A) always
for STM platforms (as long as the project inherits the trustfence class)
and set FIP_SIGN_ENABLE="0" if its sibling TRUSTFENCE_SIGN="0", so that
DEY doesn't sign the FIP image either.

For the moment, do not sign aditional artifacts, such as the ramdisk,
the kernel or the boot scripts for STM platforms.
In the specific case of the ramdisk, simply copy it over with the
expected filename extension.

The stand-alone signing script 'trustfence-sign-artifact.sh' checks
if a valid PKI tree exists (by checking the existance of four SRK
files) and if they don't, it calls trustfence-gen-pki.sh (which is
a wrapper over different generators (for HAB or AHAB) to create one.
Recipes such as 'dualboot' or 'recovery-initramfs' may need to call
openssl functions over the PKI tree. These recipes do not currently
generate the PKI tree; they expect it to be already in place.
This might not be the case if the trustfence-sign-artifact.sh script
has not been called yet.
Originally, a fake dependency on virtual/kernel recipe was made to
force it, but it doesn't quite work since the calling only happens
on deploy() while regular DEPENDS doesn't wait for this task.
If the PKI does not exist, a recipe that requires the PKI tree will
fail.
The solution is to create a function on the trustfence.bbclass that
allows any recipe to check for the existance of a PKI tree and
generate it if it doesn't exist. This is repeated inside the
trustfence-sign-artifact.sh, but it needs to be in both places
because this script must work stand-alone.
The generation of the PKI tree takes some seconds so this commit
adds a lock dir to prevent race conditions when called from
different recipes.
It also removes the fake dependency on virtual/kernel and adds a
dependency on trustfence-cst-native (which is the recipe that
provides the PKI generation tool).

Instead of overriding the whole do_compile function, just to reconfigure
u-boot for Trustfence, create a do_configure pre-function that takes care
of that. This allows the removal of duplicated code.
Also, disable the generation of u-boot environment artifacts. We are
not using them and so many u-boot artifacts in the deploy directory
are confusing.
Finally, adjust the names of the TF u-boot artifacts in the do_deploy
append function.

Signed image support in U-Boot has been split into two separate configurations:
one that adds artifact authentication support and another that signs the U-Boot
binary at the end of the build. Reflect this change in meta-digi.

This initramfs only makes sense in platforms with an eMMC as the internal
storage, due to how the partition encryption support is implemented. In
plaatforms that use NAND instead, ths initramfs offers no functionality and
increases the recovery image size, so remove it.

Previously, TRUSTFENCE_INITRAMFS_IMAGE was the only variable used to configure
rootfs encryption. Now that any partition can be encrypted and the rootfs
encryption still needs to be handled differently, use two variables instead.
* TRUSTFENCE_ENCRYPT_PARTITIONS to control partition encryption in general
* TRUSTFENCE_ENCRYPT_ROOTFS to control rootfs encryption
As with most trustfence functionality, enable both by default. Leave
TRUSTFENCE_INITRAMFS_IMAGE as an internal variable only.

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.

- 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.

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.

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.
