i.MX6: PL310: Adjust settings for performance
According to commit f6b6f3c7b2bb7d6277801882afdced6f2b10fc17 from git://git.freescale.com/imx/uboot-imx.git: Also set Prefetch offset to 15, since it improves memcpy performance by 35%. Don't enable Incr double Linefill enable since it adversely affects memcpy performance by about 32MB/s and reads by 90MB/s. Tested with 4K to 16MB sized src and dst aligned buffer. This commit ports those chagnes from U-Boot. Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
