Changes since U-Boot 1.1.4:
======================================================================
+* Enable address translation on MPC83xx
+ Patch by Kumar Gala, 10 Feb 2006
+
+* Decopuled setting of OR/BR and LBLAWBAR/LBLAWAR on MPC83xx
+ Patch by Kumar Gala, 25 Jan 2006
+
+* Fixed defines for MPC83xx SICRL register to match current specs
+ Patch by Kumar Gala, 23 Jan 2006
+
+* Fixed PCI indirect config ops to handle multiple PCI controllers
+ We need to adjust the bus number we are trying to access based
+ on which PCI controller its on
+ Patch by Kumar Gala 12 Jan 2006
+
+* Add helper function for generic flat device tree fixups for mpc83xx
+ Patch by Kumar Gala 11 Jan 2006
+
+* Add support for passing initrd information via flat device tree
+ Patch by Kumar Gala 11 Jan 2006
+
+* Added OF_STDOUT_PATH and OF_SOC
+
+ OF_STDOUT_PATH specifies the path to the device the kernel can use
+ for console output
+
+ OF_SOC specifies the proper name of the SOC node if one exists.
+ Patch by Kumar Gala 11 Jan 2006
+
+* Allow board code to fixup the flat device tree before booting a
+ kernel
+ Patch by Kumar Gala 11 Jan 2006
+
+* Added CONFIG_ options for bd_t and env in flat dev tree
+
+ CONFIG_OF_HAS_BD_T will put a copy of the bd_t
+ into the resulting flat device tree.
+
+ CONFIG_OF_HAS_UBOOT_ENV will copy the environment
+ variables from u-boot into the flat device tree
+
+ Patch by Kumar Gala 11 Jan 2006
+
+* Report back PCI bus when doing table based device config
+ Patch by Kumar Gala 11 Jan 2006
+
+* Added support for PCI prefetchable region and BARs
+ If a host controller sets up a region as prefetchable and
+ a device's BAR denotes it as prefetchable, allocate the
+ BAR into the prefetch region.
+
+ If a BAR is prefetchable and no prefetchable region has
+ been setup by the controller we fall back to allocating
+ the BAR into the normally memory region.
+ Patch by Kumar Gala 11 Jan 2006
+
+* Only disable the MPC83xx watchdog if its enabled out of reset.
+ If its disabled out of reset SW can later enable it if so desired
+ Patch by Kumar Gala, 11 Jan 2006
+
+* Allow config of GPIO direction & data registers at boot on 83xx
+ Patch by Kumar Gala, 11 Jan 2006
+
+* Enable time handling on 83xx
+ Patch by Kumar Gala, 11 Jan 2006
+
+* Make System IO Config Registers board configurable on MPC83xx
+ Patch by Kumar Gala, 11 Jan 2006
+
+* Added PCI support for MPC8349ADS board
+ Patch by Kumar Gala 11 Jan 2006
+
* Add basic support for the SMMACO4 Board from PanDaCom.

* Fix mkimage bug with multifile images created on 64 bit systems.
* Add support for 28F256J3A flash (=> 64 MB) on PM520 board
