It is very unlikely that they will work as is. You will have to change some stuff. We don't maintain lists of what needs to change. Most of the stuff should be obvious, e.g. you define a macro that is now poisoned, and you have to change the port to use the new macro that replaced the poisoned one. Most of the trouble is likely to be with the target .h file. There should be little in the md file that needs to be changed. There may be style issues that you miss with a naive port, since sometimes there are multiple ways to solve a problem, with the old ones obsoleted but not yet removed. For instance, there is now a way to define constants in the md file, and style dictates use of this. There is a new mechanism for describing hardware pipelines which is better than the old one, but the old one is still present and still works.
