   5  * These bits define which access sizes a platform can support, rather
   6  * than the maximal access size.  So, if your platform can do 16-bit
   7  * and 32-bit accesses to the SMC91x device, but not 8-bit, set both
   8  * SMC91X_USE_16BIT and SMC91X_USE_32BIT.
   9  *
  10  * The SMC91x driver requires at least one of SMC91X_USE_8BIT or
  11  * SMC91X_USE_16BIT to be supported - just setting SMC91X_USE_32BIT is
  12  * an invalid configuration.
