Subject: Re: [PATCH 2/5] Add support for the Arcom/Eurotech Viper SBC onboard ethernet.

Consider merging this to the following code in the front of smc91x.h

#if defined(CONFIG_ARCH_LUBBOCK) ||\
    defined(CONFIG_MACH_MAINSTONE) ||\
    defined(CONFIG_MACH_ZYLONITE) ||\
    defined(CONFIG_MACH_LITTLETON)

#include <asm/mach-types.h>

/* Now the bus width is specified in the platform data
 * pretend here to support all I/O access types
 */
#define SMC_CAN_USE_8BIT        1
#define SMC_CAN_USE_16BIT       1
#define SMC_CAN_USE_32BIT       1
#define SMC_NOWAIT              1

#define SMC_IO_SHIFT            (lp->io_shift)

....
#else
