I am afraid we don't have mpc55xx patch for eclipse version.
The latest version of Classic CodeWarrior for MPC55/56xx is v2.10, It can be downloaded from:
http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=CW-MPC55XX
eclipse version only supports MPC56xx, it does not support MPC55xx.
Hope this helps!
