We're using that chip connected to a PXA300 and it works well, so I
wouldn't suspect the driver. Does it work from any other scenario like
the bootloader? And I don't know OMAP, but it might be helpful to others
if you posted your platform_data config.

The platform_data I use is:
static struct smsc911x_platform_config smsc911x_config = {
	.irq_polarity = SMSC911X_IRQ_POLARITY_ACTIVE_LOW,
	.irq_type = SMSC911X_IRQ_TYPE_PUSH_PULL,
	.flags = SMSC911X_USE_32BIT | SMSC911X_FORCE_INTERNAL_PHY,
};

The chip is properly detected, and if I tweak the loopback test to return 0, the
 driver does not complain any more. Moreover, it seems that RX work, at least
ifconfig reports non-zero values for RX packets. Still, there is no even single
packet transmitted from the smsc9220 :(
I suspect that there's some problem with the hardware, and probably someone
encountered similar problems and may have found a solution.

For the electrical part, there is a reference schematic from SMSC. And
on PXA, you need some dumb CMOS logic or a CPLD for proper interfacing
of the digital bus. Don't know if the latter is also necessary for OMAP.
