So I've been hacking on it for a bit, see the first stab at [1]. As for the 
ruleset, I propose this addition for the Wiki [2]:


U-Boot code documentation

U-Boot adopted the kernel-doc annotation style, this is the only exception from 
multi-line comment rule of Coding Style. While not mandatory, adding 
documentation is strongly advised. The Linux kernel kernel-doc document [3] 
appliest with no changes.
