Nowadays, do many (PowerPC) embedded devices already risk omitting NOR flash and use a NAND device solely for booting and storing images ?
I'm talking about systems with 10 years life-cycle (so no MP3-players nor medical systems but somewhere in between).
We have a MPC8313E-RDB and I know booting from NAND is possible. U-boot seems to support it well, I assume it can read the kernel, ramdisk and dtb from NAND in memory and bootm this.
We use a 256M NAND on the PIKA Warp appliance and where unable to boot u-boot from the NAND. It worked on a smaller 64M NAND.
So we put our FPGA and u-boot in a small NOR. The kernel, rootfs and other files are on the NAND.
