ref-manual, dev-manual: Review comments applied to package repository
Changes are the review comments from Paul Eggleton regarding setting up the optional package repository on the host that can be used by Smart. These changes reflect the fact that the task is not package-type dependent or host web server dependent. (From yocto-docs rev: 779989878bcc9501ddc4570519d93325442a8493) Signed-off-by: Scott Rifenbark <scott.m.rifenbark@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
