Subject: GPMI IMX6ull timeout on dma

Hi all

I have a strange problem on booting an imx6ull system. The problem is
not systematic and seems that it depends on how bootloader is using
the nand on first stage boot. BTW kernel can not always pass to go to
edo time 5 (even 4). If I power off and power on the unit the nand
work properly.
