This seems a little big. Which template are you using? This is an
eb55?  I just build the default configuration. This is the size for
some of the kernel tests:

:~/eCos/work$ arm-elf-size install/tests/kernel/current/tests/*
   text    data     bss     dec     hex filename

Normally no. The RAM startup address map should work correctly with a
ROM redboot.
