On a sidenote: Are you currently selling these boards? I would love to get one.

Hi all,
i designed here a new board with mcf54415. Testing a first mainline kernel.
I would like to load a cramfs rootfs from SPI NOR (mtd, ftl) but actually
i don't see the SPI NOR flash detected from dmesg.
Next future step then would be load rootfs from SD.
Seems there is no selectable driver for
- SPI controller
- SD (MMC) controller
Those should be similar to existing drivers of some other freescale chip,
or some new implementation is required ? Attaching dmesg.
Regards,
Angelo Dureghello
