I, personally, am not a big fan of using structs to describe register
file layout since it makes it hard to figure out individual register's
offset just by reading the code, is compiler implementation/arch
specific (that probably wouldn't be a problem though) and goes against
the style in which majority of Linux kernel driver code(and by
extension Barebox) is written in.
However, it's up to Sascha to decide if this style is OK.
