Bugfix in I2C initialisation on S3C2400.

[u-boot.git] / CHANGELOG

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

* Bugfix in I2C initialisation on S3C2400.
  If the bus is blocked because of a previously interrupted
  transfer, up to eleven clocks are generated on the I2CSCL
  line to complete the transfer and to free the bus.
  With this fix pin I2CSCL (PG6) is really configured as GPIO
  so the clock pulses are really generated.

* Fix DDR6 errata on TQM834x boards
  Patch by Thomas Waehner, 07 Mar 2006

* Remove obsolete flash driver board/tqm5200/flash.c
  Patch by Martin Krause, 11 Jan 2006

* Update configuration for CMC-PU2 board
  Patch by Martin Krause, 17 Nov 2005

* Add support for PS/2 keyboard on TQM85xx board
  Patch by Martin Krause, 07 Nov 2005

  Tested on a STK85XX baseboard. Make sure the PS/2 controller
  has been programmed. Jumper Settings: X66 1-2, 9-10; X61 2-3

* Fix TRAB channel switching delay for trab_fkt.bin standalone applikation
  In tsc2000_read_channel() the delay after setting the multiplexer 
  to a temperature channel is increased from 1,5 ms to 10 ms. This
  is to allow the multiplexer inputs to stabilize after huge steps
  of the input signal level.
  Patch by Martin Krause, 08 Nov 2005

* Adjust TQM5200 make targets
  Make the automatic CS configuration the default.
  The dedicated configurations CONFIG_TQM5200_AA, CONFIG_TQM5200_AB
  and CONFIG_TQM5200_AC are removed.
  "TQM5200_config" is now the default for STK52XX.200 base boards.
  On a STK52XX.100 base board "TQM5200_STK100_config" must be used.
  Patch by Martin Krause, 07 Nov 2005

* Fix setting of environment variable "ver" on trab board
  The environment variable "ver" is now set before
  do_auto_update() is called, so that "ver" can be used
  in USB update scripts.
  Patch by Martin Krause, 27 Oct 2005

  We use the "automatic" mode that was used for  the  MPC8266ADS  and
  MPC8272 boards. Eventually this should be used on all boards?]

* 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

  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
