Not just compatible, they are the same. A little bit of history: I
originally brought i.MX1 support to the kernel in the early 2.6 days.
around 2.6.25 Freescale pushed initial i.MX31 support using plat-mxc. We in
turn based our i.MX27 port on this code and since then it evolved
further. Darius based a new i.MX1 support on this code and now we can
remove arch-imx.
