From 724cfb944007b7f8d346523a7810b53a35921bc5 Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Tue, 28 Apr 2009 08:02:13 +0000 Subject: [PATCH] sh: smsc911x support for the rsk7203 board This patch adds support for the LAN9118 ethernet on rsk7203. The LAN9118 controller is hooked up using a 16-bit data bus, but the rsk7203 board does not swap the byte lanes as needed between the sh7203 processor and the the ethernet controller. In the processor the CS memory window is configured in 16-bit mode but the smsc911x driver is told to do 32-bit accesses to improve performance. The SMSC911X_SWAP_FIFO flag is used to tell the driver to do software byte swapping of fifo data.
