from 2.6.29, smc911x isn't maintained anymore. A new driver, smsc911x,
will replace it. so convert omap_ldp to use smsc911x driver.

This doesn't look right - 'end' is inclusive not exclusive.  So this
reserves 257 bytes, not 256 bytes.

Hi Stanley,

This platform patch doesn't apply to linus's tree, what's it based on?

Thanks,
Steve

Thanks for the review, correct it.

Sorry, I reworked it to base on linus's tree.
