I have a ADSP-BF527 platform which has only 4 MB SPI Flash no parallel NOR Flash memory. Even for a small minimal kernel with USB support kernel + rootfs comes to 4.02 MB so we can't store it on the 4MB Flash. But since the core kernel is only 1.24MB, I was wondering if it is possible to boot linux kernel from the flash but mount rootfs from SPI based SD Card?
