> Jonathon, Thank you for preparing this patch. […]

I commented on CB:66659 about the biggest problems I saw. If you want to get rid of the `programmer_param` global variable, CB:67094 is a great starting point, as it constrains the `programmer_param` global variable to the scope of the `programmer_init()` function. One would only need to plumb the variable through several function calls.
