Subject: davinci: fb: fix frame buffer driver issues
From: Sudhakar Rajashekhara <sudhakar.raj@xxxxxx>
Following issues have been addressed on DA8XX/OMAP-L1XX:
a. Screen misalignment during booting when frame buffer console is
enabled.
b. Driver was configured always in PSEUDOCOLOR mode. This patch
dynamically configures the driver either in PSEUDOCOLOUR or TRUECOLOR
mode depending on bpp.
c. The RED and BLUE offsets were interchanged resulting in wrong
bootup logo colour.
This patch has been tested on DA830/OMAP-L137 and DA850/OMAP-L138 EVMs.
