There are two possible choices for UART0, UART1, and SPI on kirkwood..

For instance I use this on my board:

                                pmx_spi0: pmx-spi0 {
                                        marvell,pins = "mpp7", "mpp10", "mpp11", "mpp12";
                                        marvell,function = "spi";
                                };

It looks like all the boards in the kernel use the same choice, so it
makes some sense to consolidate, but I assume a board file can
override the marvell,pins?

Otherwise the rest of your patchset looked sane to me.
