Make R5200 specific low level initialization board conditional.

[u-boot.git] / CHANGELOG

======================================================================
Changes since U-Boot 1.1.4:
======================================================================

* Make R5200 specific low level initialization board conditional.

* Update CPU target identification strings for Coldfire family.

* Update register definitions for MCF5271.

* Fix serial console support for MCF5271.

* Fixes for gcc 3.4 based m68k toolchain,
  based on patch by Jate Sujjavanich.

* Added support for BC3450 board
  Patch by Stefan Strobl, 21. Oct 2005

* Update for NC650 board:
  - Support rev1 and rev2 hardware
  - adapt to new NAND layer
  - add CP850 configuration based on NC650

* MPC5200: enable snooping of DMA transactions on XLB even if no PCI
  is configured; othrwise DMA accesses aren't cache coherent which
  causes for example USB to fail.

* Some code cleanup

* Fix dbau1x00 boards broken by dbau1550 patch
  PLL:s were not set for boards other than 1550.
  Flash CFI caused card to hang due to undefined CFG_FLASH_BANKS_LIST.
  Default boot is now bootp for cards other than 1550.
  Patch by Thomas Lange, 10 Aug 2005

* Fixes common/cmd_flash.c:
  - fix some compiler/parser error, if using m68k tool chain
  - optical fix for protect on/off all messages, if using more
    then one bank
  Patch by Jens Scharsig, 28 Jul 2005

* Fix Quad UART mapping on MCC200 board due to new HW revision

* 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

* Changes/fixes for drivers/cfi_flash.c:

  - Add Intel legacy lock/unlock support to common CFI driver

    On some Intel flash's (e.g. Intel J3) legacy unlocking is
    supported, meaning that unlocking of one sector will unlock
    all sectors of this bank. Using this feature, unlocking
    of all sectors upon startup (via env var "unlock=yes") will
    get much faster.

  - Fixed problem with multiple reads of envronment variable
    "unlock" as pointed out by Reinhard Arlt & Anders Larsen.

  - Removed unwanted linefeeds from "protect" command when
    CFG_FLASH_PROTECTION is enabled.

  - Changed p3p400 board to use CFG_FLASH_PROTECTION

  Patch by Stefan Roese, 01 Apr 2006

* Changes/fixes for drivers/cfi_flash.c:
  - Correctly handle the cases where CFG_HZ != 1000 (several
    XScale-based boards)
  - Fix the timeout calculation of buffered writes (off by a
    factor of 1000)
  Patch by Anders Larsen, 31 Mar 2006

* Updates to common PPC4xx onboard (DDR)SDRAM init code (405 and 440)

  405 SDRAM: - The SDRAM parameters can now be defined in the board
	       config file and the 405 SDRAM controller values will
	       be calculated upon bootup (see PPChameleonEVB).
	       When those settings are not defined in the board
	       config file, the register setup will be as it is now,
	       so this implementation should not break any current
	       design using this code.

	       Thanks to Andrea Marson from DAVE for this patch.

  440 DDR:   - Added function sdram_tr1_set to auto calculate the
	       TR1 value for the DDR.
	     - Added ECC support (see p3p440).

  Patch by Stefan Roese, 17 Mar 2006

* Fix CONFIG_SKIP_LOWLEVEL_INIT dependency in cpu/arm920t/start.S
  Patch by Peter Menzebach, 13 Oct 2005 [DNX#2006040142000473]

* Add support for ymodem protocol download
  Patch by Stefano Babic, 29 Mar 2006

* Memory Map Update for Delta board: U-Boot is at 0x80000000-0x84000000
