35  * This file is an extension to the delegation client for SMC omap3. It
36  * permits to manage two differences with the original client:
37  *  - command line parsing to take into account a file as input
38  *  - associate a specific path to each partition

53  * This function :
54  *    1) parses the configuration file of the SMC
55  *    2) checks that all mandatory partition name are present and valid
56  *    3) associates partition names to one of the 16 partition IDs
57  *    4) Mapping is as follow:
58  *          -- partition 0 <--> File System
59  *          -- partition 1 <--> Keystore System
60  *          -- partition 2 <--> Keystore User
61  *          -- partition 15 <--> Super Partition
62  *
63  * It returns 0 in case of success and the error code requested by tf_daemon otherwise.
