@@ -15,6 +15,23 @@ Changes since U-Boot 1.1.4:
* Change "mii info" to not print an error upon missing PHY at address
Patch by Stefan Roese, 07 Aug 2006
+* Fix PCI-Express on PPC440SPe rev. A.
+
+* Fix preboot message on TQM85xx after switching to hush parser.
+
+* Adapt TQM85xx ramdisk address to Linux kernel memory map
+
+* Add initial support for PCI-Express on PPC440SPe (Yucca board).
+
+* Fix compiler warning for TRAB board.
+ Patch by Martin Krause, 07 Aug 2006
+
+* Prevent USB commands from working when USB is stopped.
+
+* Add rudimentary handling of alternate settings of USB interfaces.
+ This is in order to fix issues with some USB sticks timing out
+ during initialization. Some code readability improvements.
+
* PPC440 DDR setup: Set SDRAM0_CFG0[PMU]=0 for best performance
AMCC suggested to set the PMU bit to 0 for best performace on
the PPC440 DDR controller.
