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