Commit Message

Valek, Andrej Nov. 10, 2020, 9:07 a.m. UTC
Firmware file loadind for GT911 controller takes too much time (~60s).
There is no check that configuration is the same which is already present.
This happens always during boot, which makes touchscreen unusable.

Add there an option to prevent firmware file loading, but keep it enabled
by default.
