[U-Boot] [PATCH] smc911x_eeprom: new example app for managing newer SMC parts

Mike Frysinger vapier at gentoo.org
Thu Dec 11 02:46:08 CET 2008


A forward port of the last version to work with the newer smc911x driver.
A bunch of simple functions/defines had to be split out of the smc911x
driver to avoid ugly code duplication in the eeprom programmer.

I only have a board with a LAN9218 part on it, so that is the only one
I've tested.  But there isn't anything in this that would make it terribly
chip specific afaik.
