The hexdump library was ported from Linux which supports different printk() level. Because the barebox print* facility is different compared to the one from Linux the barebox printk() doesn't support levels. Therefore the level is always set to an empty string.
Furthermore all barebox printk() calls aren't recorded by the internal barebox_logbuf because they are mostly used for command prints. Linux on the other hand record each printk() print. Not recording the output can be an issue on systems which don't have a hw-console but a USB-ACM console, because the hexdump call may already occurred before the console was ready. Make use of pr_print() instead to record the output within the barebox_logbuf to be available later on via dmesg. With that the hexdump API changes from a string based loglevel to a integer based loglevel parameter.
