The patch titled LL TEMAC driver: add non-Virtex 5 support has been removed from the -mm tree. Its filename was ll-temac-driver-add-non-virtex-5-support.patch This patch was dropped because an updated version will be merged The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: LL TEMAC driver: add non-Virtex 5 support From: John Tyner <jtyner@xxxxxxxxxx> Add support for using the LL TEMAC Ethernet driver on non-Virtex 5 platforms by adding support for accessing the Soft DMA registers as if they were memory mapped instead of solely through the DCR's (available on the Virtex 5).
