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.
