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.
