 Changes since U-Boot 1.1.4:
 ======================================================================
 
+* Fix JFFS2 support for legacy NAND driver.
+
+* Remove dependencies between DoC code and old legacy NAND driver.
+
+* Fix PM828_PCI target, for which PCI was *not* configured in.
+
 * Fix Lite5200B support: initialize SDelay register
   See Freescale's AN3221 "MPC5200B SDRAM Initialization and
   Configuration", 3.3.1 SDelay--MBAR + 0x0190
