11	  If unsure, say Y.

13	  Note that the answer to this question doesn't directly affect the
14	  kernel: saying N will just cause the configurator to skip all
15	  the remaining Blackfin card questions. If you say Y, you will be
16	  asked for your specific card in the following questions.

29	  it compiled into the kernel. This driver is also available as a
30	  module ( = code which can be inserted in and removed from the running
