There are a few small caveats at the present: 1. Relies on "Add support to STMicroeletronics STM32 family", v8 by Maxime Coquelin: http://thread.gmane.org/gmane.linux.kernel.cross-arch/27569 2. Allocating ~80 clock components appears to fragment memory enough to prevent busybox (.text is ~300K, non-XIP) from running getty. I have to use "init=/bin/sh" to avoid OOM problems. 3. Support for I2S and SAI is not included in this patchset.
