This patch modifies the Trusted Board Boot implementation to use the new authentication framework, making use of the authentication module, the cryto module and the image parser module to authenticate the images in the Chain of Trust. A new function 'load_auth_image()' has been implemented. When TBB is enabled, this function will call the authentication module to authenticate parent images following the CoT up to the root of trust to finally load and authenticate the requested image. The platform is responsible for picking up the right makefiles to build the corresponding cryptographic and image parser libraries. ARM platforms use the mbedTLS based libraries. The platform may also specify what key algorithm should be used to sign the certificates. This is done by declaring the 'KEY_ALG' variable in the platform makefile. FVP and Juno use ECDSA keys. On ARM platforms, BL2 and BL1-RW regions have been increased 4KB each to accommodate the ECDSA code. REMOVED BUILD OPTIONS: * 'AUTH_MOD' Change-Id: I47d436589fc213a39edf5f5297bbd955f15ae867
