[U-Boot] "make htmldocs" gives error

[Abraham V.]

Hello everyone,
(cc Simon Glass)

I just tried to make the documentation for uboot with the following
command (checked out latest mainline sources);

> make htmldocs
cc     tools/kernel-doc/docproc.c   -o tools/kernel-doc/docproc
make U_BOOT_VERSION=2014.01-rc1 -C doc/DocBook/ htmldocs

The logs in doc/Docbook/Makefile indicate that it was Simon's commit
which is causing this problem (at least, he's the one who added in the
fs.xml dependency without committing said file). But even if I remove
this from the Makefile;

We can see that there's some issue with parsing the comments in the
linker_lists.h header file.

I can understand general developer reluctance at updating
documentation (I'm lazy about it too), but do we have any way to
generate some kind of documentation for u-boot? Even Linux-style man
pages will do.

Or is my only recourse to just refer all the doc/README.* files one at a time?
