This is more like the 2.4 legacy stuff, and is at least confusing and unclear now. To keep the world comfortable, a new mechanism is introduced: before accessing specific immr register/register set, one needs to map it, using cpm2_map(), for instance, access to CPM command register will look like volatile cpm_cpm2_t *cp = cpm2_map(im_cpm); keeping the code clear, yet without "already defined somewhere" cpm2_immr. So far, unmapping code is not implemented, but it's not a big deal to add it, if the whole idea makes sense.
