Previous versions used full wait states for the chip select #1 which is connected to the Xilinix SystemACE controller on the AMCC Katmai evaluation board. This leads to really slow access and therefore low performance. This patch now sets up the chip select a lot faster resulting in much better read/write performance of the Linux driver.
