torsten demke sent me a set of patches for SMC1 relocation and they
included the following addition to cpm_uart_core.c:

AFAICT, the added code at the bottom is because, when you relocate
SMC1, you lose some functionality. is there, somewhere, i can read
up on what the above is fixing? thanks. i think that's the last
piece of the puzzle -- all the rest of the changes make sense.
