Subject: i.MX6: arm2: Add AXI cache and Qos setting
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=03f3587822839d90b1b118d3cd51c59d8b4d5b32;p=u-boot.git

i.MX6: arm2: Add AXI cache and Qos setting

Do the same AXI cache and Qos settings done already in the
SabreLite imximage.cfg for the ARM2 board, too.

It fixes a display flash issue caused by low priority of
the display IDMA channel.
