this looks wrong, because CMD_BLOB sounds like a generic command but it
will automatically select FSL_BLOB which in turn sounds freescale specific.
Looking at the help text, this command is (at least at the moment) freescale
specific, but the code seems to be generic and the blob_encap() and
blob_decap() are weak functions, thus they could be implemented in a
different way and not just by fsl_blob.c.

I don't think this should automatically select FSL_BLOB.

Also, shouldn't this be an uclass with encap and decap ops?

wrong indendation?
