[BUG] binman: Add a library to access binman entries

[Frank Wunderlich]

Hi,

this Patch seems to break init-chain at least on bpi-r64 if BINMAN_FDT not 
disabled (enabled by default). adding some code for debugging

38 int binman_init(void)
39 {
40         binman = malloc(sizeof(struct binman_info));
41         printf("%s:%d",__FUNCTION__,__LINE__);
42         if (!binman)
43                 return log_msg_ret("space for binman", -ENOMEM);
44         printf("%s:%d",__FUNCTION__,__LINE__);
45         binman->image = ofnode_path("/binman");
46         printf("%s:%d",__FUNCTION__,__LINE__);
47         if (!ofnode_valid(binman->image))
48                 return log_msg_ret("binman node", -EINVAL); <<<<<<<<<<< this 
seems to break init-flow
49
50         printf("%s:%d",__FUNCTION__,__LINE__);
51         return 0;
52 }

results in this:

binman_init:41binman_init:44binman_init:46initcall sequence 000000004ffd2588 
failed at call 0000000041e0cdec (err=-22)
