Another option here instead of re-defining the struct is to includ the
original header and just change the values you need to. That way
you can describe the reasons behind the values that are changing.

Was this a copy-paste from Beagle? Certain revs of beagle had this
limitation due to a board design problem, so unless you've inherited the
same board-design problem, you should be find with the default.
