In my situation, Common Ethernet Support added, and ethernet work well
when I use internal ram as main ram. But when I use external dram as
main ram, ethernet does not work :).

Although my eCos work with K70 but it does not work with other boards
& many hard-code for K70 only :). On the other hand, my main purpose
when using Redboot for K70 is booting Linux kernel for it. So if you
have done Redboot for K70 and it works well, please share it soon ^^!
I think it better than mine.
