[U-Boot] [PATCH V2 0/5] Add support for additional splash screen locations

[Nikita Kiryanov]

This series adds the following functionality to the splash_source library:
- load splash image from filesystem formatted usb storage
- load splash image from filesystem formatted mmc storage
- load splash image from filesystem formatted sata storage

Finally, use the new features on cm-fx6.

Changes in V2:
	- Rebased over current mainline.
	- Added "splashfile" env variable to select splash file name dynamically.
	  Also available: default value "splash.bmp"
	- Added documentation for the feature.
	- Refactored device initialization code so that #ifdefs are outside of
	  the functions. This affects patches 3 and 4.
