 ======================================================================
 
+* Fix watchdog handling in CFI flash driver
+  Just use udelay() when waiting for status changes which will
+  implicitely trigger the watchdog.
+
 * Fix PCI to memory window size problems on PM82x boards
   We use the "automatic" mode that was used for  the  MPC8266ADS  and
   MPC8272 boards. Eventually this should be used on all boards?]
