It is probable that the EDB9307/12/15 boards use RedBoot to boot
Linux. RedBoot is part of eCos, and Cirrus may not have pruned the
unnecessary parts of the eCos tree when adding it to the BSP.

eCos is not a self supporting operating system, it needs a host OS to
configure and build the OS and application, which is then downloaded
to the target board.

The only real connection between eCos and Linux is that Linux is the
preferred development environment for eCos. Development can also be
done on Windows using Cygwin, and it probably wouldn't be too hard to
get things working on BSD, Solaris or any other UNIX OS.
