[U-Boot] [PATCH v3 03/12] image: Add CONFIG_FIT_SPL_PRINT to control FIT image printing in SPL

[Simon Glass]

This code is very large, and in SPL it isn't always useful to print
out image information (in fact there might not even be a console
active). So disable this feature unless this option is set.
