I'm fine with keeping them if there is driver support, but they do need
to be moved into the common framework. However I don't think it is worth
keeping dead code just be a driver _might_ appear. The mAgic code has
been sitting in the the kernel for over two years with no users.
Especially with the current push to reduce the size of the ARM tree, it
needs to go.
