DESCRIPTION

This library provides errata patch for quicc engine microcode.

*/

/* Supplied by Freescale */

/* This patch will tell the QUICC Engine that there is a ucode patch in the IRAM (cercr commands).  
You may need to change the base address to match your configuration.  The base address used is
0xE0xx_xxxx.
