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.
