@ -14,6 +14,56 @@ Changes since U-Boot 1.1.4:
by default with the Adder87x U-Boot port.
Patch by Bryan O'Donoghue <bodonoghue@codehermit.ie>, 29 May 2006
* Fix IxEthDB.h to compile again
Patch by Stefan Roese, 14 Jun 2006
* Minor cleanup for PCS440EP board
Patch by Stefan Roese, 13 Jun 2006
* Add MCF5282 support (without preloader)
relocate ichache_State to ram
u-boot can run from internal flash
Add EB+MCF-EV123 board support.
Add m68k Boards to MAKEALL
Patch from Jens Scharsig, 08 Aug 2005
* Nios II - Add Altera EP1C20, EP1S10 and EP1S40 boards
Patch by Scott McNutt, 08 Jun 2006
* Nios II - Add EPCS Controller bootrom work-around
-When booting from an epcs controller, the epcs bootrom may leave the
slave select in an asserted state causing soft reset hang. This
patch ensures slave select is negated at reset.
Patch by Scott McNutt, 08 Jun 2006
* Update PK1C20 board
-Update base addresses for standard configuration
-Eliminate use of CACHE_BYPASS in board code
Patch by Scott McNutt, 08 Jun 2006
* Nios II - Fix I/O Macros and mini-app stubs
-Fix asm/io.h macros
-Eliminate use of CACHE_BYPASS in cpu code
-Eliminate assembler warnings
-Fix mini-app stubs and force no small data
Patch by Scott McNutt, 08 Jun 2006
* Fix U-Boot environment sector protection on MCC200 board
* Minor cleanup for PCS440EP board
* Update PCS440EP port to fit into one flash device (incl. environment)
Patch by Stefan Roese, 06 Jun 2006
* Add support for PCS440EP board
Patch by Stefan Roese, 02 Jun 2006
* Fix examples/Makefile; some build targets were lost
* 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?]
