  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.
