This series adds support for strl(cat|cpy), and brings their implementations in-line with what is documented in the Linux man pages. It also fixes some potential (actual) fastboot bugs. Lastly, it adds a patman check to suggest using these functions over strn(cat|cpy). I think these functions provide a much better interface, which removes some footguns from U-Boot.
