This is the same IP block as used in PXA, right? With few modifications here and there. Is there a reason not to use spi-pxa2xx.c? I have a set of patches for spi-pxa2xx.c that adds support for Lynxpoint LPSS, DMA engine and ACPI enumeration. I'm hoping to send those soon (once -rc1 is released) to the list. Maybe we can co-operate to get the Medfield support there as well?
