Some documentations such as the the Porting Guide are still inline with
rtems-4.5.0 and hence to some extent out of date.

depends on what you're porting
finding a similar existing port and having it as a guideline is probably
the best
regarding makefiles, you can find some useful stuff in mailing list
archives, but eventually it boils down to 3 main things
bootstrap (to create all configure & Makefile.in files)

I think your statement is correct
