[U-Boot] [PATCH 10/14] compulab: splash: refactor splash.c

Nikita Kiryanov
2015-01-14T08:42:50Z

Move storage device specific code into its own function instead of
calling it directly from an otherwise storage device independent
function (cl_splash_screen_prepare).

This is a preparation for supporting multiple splash locations.
