Hi Anatolij,
I hate to come in late to the discussion, but while testing [1] with cache
enabled, I started down the path of fixing up code paths within
drivers/video/cfb_console.c that are followed by SABRE Lite as you did in [2].
[1] [PATCH V2 0/2] i.MX6: mx6qsabrelite: Add splash screen

Data cache flushing is required for frame buffer in RAM to fix the
distorted console text output. Currently this text distortion is
observed with cfb on beageboard and N900 when running with data
cache enabled.
