This is just a draft to discuss ideas related to "Make U-Boot log great
again" thread.
With this patch we will see something like:
Loading Environment from FAT...
--> MMC: no card present
--> ** Bad device mmc 0 **
--> Failed (-5)
Loading Environment from MMC...
--> OK
instead of:
Loading Environment from FAT... MMC: no card present
** Bad device mmc 0 **
Failed (-5)
Loading Environment from MMC... OK
