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
Disclaimer: I'm not running ppc these days
However, having no NOR flash means:
- NAND should be programmable via JTAG (BDI3000 doesn't support
this, Lauterbach/trace32 does)
My personal preference for bringing up a new board is placing u-boot
in RAM using the available information to

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.
Currently you need to define the page-size of the NAND used for booting (512
bytes vs. 2k). The 2k 4xx NAND booting
