These comments should be removed (or moved), right?

[amogh.bihani, 2014/04/25 08:57:19]

this is what should ideally be given "probably" but because we do not know which
platform would support which profile we cannot decisively say that this is
"probably".
And even in various profiles there are many variations like
baseline profile: .42E01E, .4D401E, .4D001E, .42001E
high: .64001E, .640028 etc.
