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.
