The KeyGen tool to generate 8 key pairs requires 8 consecutive passwords,
however, when the shell expands the passwords variable, it interprets it as a
single string instead of 8 different strings and fails.

Create a new script for the generation of PKI tree for STM platforms
and leave the trustfence-sign-artifact script exclusively for signing.
The new gen-pki script only requires the platform as an argument and the
path to where to save the tree (if it doesn't exist) in
CONFIG_SIGN_KEYS_PATH.
This commit also reverts commit 13c136dbc5 by getting rid of the
trustfence-genpki-native.bb recipe and moving back the PKI generation
functions into trustfence.bbclass. This recipe didn't quite guarantee
that the PKI was generated on time for the recipes that required the
keys to exist, anyway.
Instead, the PKI generation function must be called right after
do_compile() of recipe tf-a-stm32mp to be ready for do_deploy() where
the key is used.

This script can be called stand-alone or from DEY.
Syntax is :
trustfence-sign-artifact.sh -p <platform> [-t input-unsigned-image> <output-signed-image>]
If files are omitted, it at least generates random keys if they do not
exist.

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).

The sign mode needed for each platform is invariable, and since the platform
is already a mandatory parameter for the script, we can store this information
implicitly. Reflect this change in every recipe where the script is used, but
keep the variable at the Yocto level since it's still needed in several places.

The AHAB decryption process takes the encrypted file from the address defined
in U-Boot and decrypts it into the address defined in this script. If both
addresses are the same, the decryption process ends up failing. This
happens even for signed-only images.
Maintain the original addresses in this script so they do not collide.
This reverts commit c970d87d5a.

Attempting to boot encrypted artifacts on these platforms will result in HAB
events caused by CAAM errors. This is due to the CAAM being configured for
non-secure contexts (in regards to Trustzone) while the HAB expects it to be
configured for secure contexts.
For now, only sign artifacts for these platforms even if the project has the
encryption feature enabled.

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.

The only script that needs to generate the SRK_efuses is the sign.sh
script in the U-Boot code. For the rest of signed non-bootable artifacts
this is not required and it was creating the SRK_efuses file on every
recipe where the script was called, like linux-dey and others, which
eventually resulted in a conflict when copying the artifacts to the shared
deploy-image-dir.

- The IVT table address inside the kernel image must be aligned at 0x1000
bytes. The calculation of this offset was not working when the kernel image
size was multiple of 0x1000 bytes. In this case the IVT table was moved an
extra offset of 0x1000 bytes, causing U-Boot to fail to validate the image
as the IVT table was not in the expected location.
This fix uses the same offset calculation algorithm as U-Boot, ensuring both,
the sign script and U-Boot will look for the IVT at the same address.

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.

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.
