11CMD55 assumed to be nonexistent for MMC
12
13The controller FSM assumes that MMC cards result with
14"Illegal Command" from CMD55. The card will be detected as an MMC once CMD55
15has been accepted. However, the MMC standard defines this command,
16thus it is not save to rely on its nonexistence. Instead also a path from
17ACMD41 to CMD1 should be established.
