I think you've misunderstood what Boris meant. The idea of specifying a 
dependency on a patch set is assuming that entire series is already 
applied to the main branch, and then creating patches on top of those.

So, for example, you can checkout the 'master' branch of linux-next. 
Then apply all 19 of my patches on top of that branch by using 'git am'. 
Then you add your work there and separate it out on a set of commits.

If you'd to that, you won't need to add a separate patch for parsing the 
Profile 1.0 table because I've already done that in my series. All you 
need to do is add the extra things, like adding parsing of a DWORD that 
my series doesn't, or adding support for your Macronix flash.
