The MPC8349E can be booted such that the core is held in reset, and the processor registers can be configured over PCI by another host computer. Therefore it is conceivable that the host can program the SDRAM controller on the MPC8349E and take the core out of reset. If the core is configured to boot from an address mapped to SDRAM, then U-Boot could have been copied to SDRAM by the host. Once U-Boot boots, it could then use FTP etc to boot the kernel blah blah ...
Ok fine, but you're talking about an 8349 on a different board. I have a *board* header file for the MPC8349E-mITX, which comes with 16MB of flash and works just fine. I've done the hard work of getting U-Boot running on that board with flash. So the question is, am I going to upset someone if I remove support for booting from RAM on that board?
