[U-Boot] [PATCH v3] [ARM] at91: Add support for taskit AT91SAM9G20 boards
Achim Ehrlich
aehrlich at taskit.de
Tue Apr 20 17:12:41 CEST 2010
This adds support for the AT91SAM9G20 boards by taskit GmbH.
Both boards, Stamp9G20 and PortuxG20, are integrated in one file.
PortuxG20 is basically a SBC built around Stam9G20.
