   4 Subject: [PATCH 071/149] I2C: OMAP1/OMAP2+: create omap I2C functionality flags for each cpu_... test
   5
   6 These represent the 8 kinds of implementation functionality
   7 that up until now were inferred by the 16 remaining cpu_...()
   8 tests in the omap i2c driver.
   9
  10 Changed to use BIT() as suggested by Balaji T Krishnamoorthy.
