- Implements little-endian support (powerpc64le)
- Adds 'hw.ofwfb.physaddr' kernel parameter so user can manually provide correct address if it's not detected correctly
- Adds 'hw.ofwfb.argb32_pixel' so user can set it manually if colors are inverted due to incorrect pixel format (default value is 1)
- Automatically selects RGBA32 pixel format if NVidia graphic adapter is detected (sets hw.ofwfb.argb32_pixel=0)
During tests it was observed that machines equipped with NVidia graphic adapters tend to use RGBA32 pixel format. By default ARGB32 pixel format is used, proved to work on machines equipped with ATI graphic adapter and the onboard adapter used on Talos II and Blackbird machines from Raptor Computing Systems.
