[U-Boot] kernel-doc vs Doxygen

[Sam Protsenko]

Hi everyone,

Quick question: which comment style is allowed in U-Boot, kernel-doc
or Doxygen one? I have noticed that both are used currently (and I've
sent some patches with doxy comments myself). Please tell me if
somebody is actually running either kernel-doc or Doxygen to generate
the U-Boot documentation. If one particular style is preferred, maybe
it's worth to mention it somewhere in doc/ or in README.

Thanks!
