MLK-12013 arm: imx: set eim_slow clk to 132Mhz only for MXC_CPU_IMX6Q A patch(set imx6qp eim_slow to 132Mh) was pushed to eliminate the weim nor read performance drop cause by the IP difference between imx6q & imx6qp. However, the patch impacted the performance of imx6dl-ard. In succession, AXI clk is set to 270M which exceeds the max value(264M). This patch sets eim_slow to 132M only for MXC_CPU_IMX6Q. So the performance difference between imx6q & imx6qp decreases while no impact for imx6dl-ard. please see the following summary of weim nor read performance. clk(performance) 6q-sabreauto 6qp-sabreauto 6dl-ard imx_3.10 132M(18.9MB/s) —— 135M(19.1MB/s) imx_3.14.y 132M(18.9MB/s) 132M(16.8MB/s) 135M(19.1MB/s) Signed-off-by: Gao Pan <b54642@freescale.com> (cherry picked from commit f19e9899eacddb5343e7a7d476a500cd4551dffe)
