This test verifies different type of secure boot images to authentication and
decryption using AES and RSA features for AMD's Zynq SoC.
Note: This test relies on boardenv_* containing configuration values to define
the network available and files to be used for testing. Without this, this test
will be automatically skipped. It also relies on dhcp or setup_static net test
to support tftp to load files from a TFTP server.
For example:
# Details regarding the files that may be read from a TFTP server and addresses
# and size for aes and rsa cases respectively. This variable may be omitted or
# set to None if zynqmp secure testing is not possible or desired.
