More on MCP750 init failure

[valette at crf.canon.fr (VALETTE Eric)]

I tracked down the bug to be a bug in rtems_filesystem_initialize
at the end more precisely in the mkdir command.

  status = mkdir( "/dev", S_IRWXU | S_IRWXG | S_IRWXO );
  if ( status != 0 )
    rtems_fatal_error_occurred( 0xABCD0003 );

then I chased the bug a little bit more and found it to occur in
IMFS_evaluate_for_make . I hope it will ring the bell to someone...

Here are the traces :

IMFS_evaluate_for_make 1 path[i] = dev
IMFS_evaluate_for_make 2 IMFS_get_token returns type = 1 len = 1 token = d >0
IMFS_evaluate_for_make 3
IMFS_evaluate_for_make 4
IMFS_evaluate_for_make 1 path[i] = ev
IMFS_evaluate_for_make 2 IMFS_get_token returns type = 1 len = 1 token = e >0
IMFS_evaluate_for_make 3
IMFS_evaluate_for_make 4
IMFS_evaluate_for_make 1 path[i] = v
IMFS_evaluate_for_make 2 IMFS_get_token returns type = 1 len = 1 token = v >0
IMFS_evaluate_for_make 3
IMFS_evaluate_for_make 4
IMFS_evaluate_for_make 1 path[i] = 
IMFS_evaluate_for_make 2 IMFS_get_token returns type = 0 len = 0 token = 
IMFS_evaluate_for_make 3
IMFS_evaluate_for_make 4
IMFS_evaluate_for_make 17
