At present we have two ways of showing a hex dump. Once has been in U-Boot since the dawn of time and the other was recently added from Linux.
They both have their own unique features.
This series makes a few changes to bring them closer together. It also adds support for logging a buffer, which is useful since it can put it through the same log drivers as other logging output.
Also it adds tests, so we can check the behaviour.
The code-size impact of the main part of this series is 160 bytes on Thumb2, which seems acceptable. However the final patch adds another 600 bytes or so, which is not.
