[ECOS] Building eCos hello world

[David Ho]

Hi,

I am attempting to build an eCos hello world app, but I have quickly
stumbled on an issue.
As I am investigating I found that the platform specific serial port
code is missing, and I noticed it is _not active_ because
IO_SERIAL_DEVICES is disabled.

Now does eCos have a default ecm file like RedBoot? (e.g.redboot_RAM.ecm).
What would be a way to enable it by default?

Thanks, David
