Make code better readable.

[J-u-boot.git] / CHANGELOG

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

* Make code better readable.
  Patch by Ladislav Michl, 14 Sep 2005

* Enable initrd ATAG for xm250 board.
  Patch by Josef Wagner, 05 Sep 2005
  
* Add readline cmdline-editing extension
  Patch by JinHua Luo, 01 Sep 2005
  
* Add support for friendly-arm SBC-2410X board
  Patch by JinHua Luo, 01 Sep 2005
  
* Fix multi-part image support on i386 platform.
  Patch by David Updegraff, 19 Aug 2005

* Add support for KVME080 board
  Patch by Sangmoon Kim, 18 Aug 2005

* Fix MIPS LE build problem
  Patch by Matej Kupljen, 10 Aug 2005

* Check argument count in "mii" command.
  Problem pointed out by Andrew Dyer, 13 Jun 2005

* Cleanup TQM5200 board configurations:
  - make highboot configurations use environment at high end, too,
    to avoid flash fragmentation
  - always use redundand environment
  - don't enable video code for modules without graphics controller
  - provide useful (though different) mtdparts settings
  - get rid of CONFIG_CS_AUTOCONF which was always set anyway

* Extend mkconfig tool to print more useful target name

* Add support for high-boot on TQM5200 and TQM5200S boards.
  Hint: the CPLD on the TQM5200 must be programmed with a software
  version supporting the high boot option! The new TQM5200S is
  already supporting this option. On the TQM5200 this option will be
  supported in configurations with MPC5200 rev B processors.
  To actually "high boot", set jumper X30 on the STK52xx.
  Patch by Martin Krause, 12 Jul 2006

* Add support for new TQM5200 revisions
  - Support for TQM5200S (short version without graphic controller)
  - Support for modules with 'N' type S29GL128N Spansion flashes
    (requires changes to flash layout)
  - Support for MPC5200B cpu (mostly support for second SDRAM bank)
  Patch by Martin Krause, 07 Jul 2006

* Fix support for PS/2 keyboard on TQM85xx boards
  The PS/2 keyobard driver for the TQM85xx modules only supports the
  internal DUART of the MPC85xx CPU. Since the MPC8560 doesn't
  include a DUART, the TQM8560 modules can't be used with the PS/2
  keyboard controller on the STK85xx board.
  The PS/2 keyboard driver should work with the modules TQM8540,
  TQM8541 and TQM8555, but it only has been tested on a TQM8540, yet.
  Make sure the PS/2 controller on the STK85xx is programmed. Jumper
  settings: X66 1-2, 9-10; X61 2-3
  Patch by Martin Krause, 21 Jun 2006

* Adjust RTC century handling on STK52xx board to match Linux driver.
  Patch by Martin Krause, 12 Jun 2006

* Adjust filenames for USB update images on TRAB board.
  During an automatic update via USB stick, U-Boot searches for
  images with the name "firmware.img" and "kernel.img". This names
  are now changed to "firmw_01.img" and "kernl_01.img". This is done,
  to prevent updates of new boards (with the new macronics "c" step
  flashes) with old, incompatible firmware or kernel versions.
  Patch by Martin Krause, 21 Jun 2006

* Bugfix in VFD routine on TRAB board.
  Make sure upper lext pixel can be set to blue, too
  (so far only red was possible).
  Patch by Martin Krause, 15 Feb 2006

* Enable buffered flash writes for TB5200 board.

* Fix some bugs in TRAB board flash driver.
  - increase CFG_FLASH_ERASE_TOUT from 2 to 15 seconds
  - use CFG_FLASH_WRITE_TOUT for programming instead of CFG_FLASH_ERASE_TOUT
  - remove "Unlock Bypass" mode, because macronix flashes do not support
    this mode officially
  - fix flash reset command from 0x00FF to 0x00F0. 0x00FF is only specified
    for Intel compatible flashes, not for AMD compatible.
  Patch by Martin Krause, 15 Feb 2006

* Add additional error messages to flash driver on TRAB board
  (for erase errors and timeout errors)
  Patch by Martin Krause, 14 Feb 2006

* Add support for TB5200 board
  The TB5200 ("Tinybox") is a small baseboard for the TQM5200 module
  integrated in a little aluminium case.
  Patch by Martin Krause, 8 Jun 2006

* Enable buffered flash writes for TQM5200 board.

* Fix problems with SanDisk Corporation Cruzer Micro USB memory stick.

* Add support for TQM885D board.
  Patch by Martin Krause, 20 Mar 2006

* Fix FEC initialisation: All MII configuration is done via FEC1
  registers, but MII_SPEED was configured according to FEC used. So
  if only FEC2 was used, this caused the real MII_SPEED register in
  FEC1 to stay uninitalised, leqading to "mii_send STUCK!" messages.
  Fix: always configure MII_SPEED on FEC1 only.
  Patch by Markus Klotzbuecher, 12 Jul 2006

* Add support for SPC1920 board.
  Patch by Markus Klotzbuecher, 12 Jul 2006

* MCC200 board: support console on any one of the Quad UART ports.

* Fix error in flash protection calculation on MCC200 board.

* Major PCMCIA Cleanup to make code better readable and maintainable.
  Notes:
  - Board-dependend code for RPXLITE and RPXCLASSIC-based boards
    placed to the drivers/rpx_pmcia.c file to avoid duplication.
    Same for TQM8xx-based boards (drivers/tqm8xx_pmcia.c).
  - drivers/i82365.c has been split into two parts located at
    board/atc/ti113x.c and board/cpc45/pd67290.c (ATC and CPC45 are
    the only boards using CONFIG_82365).
  - Changes were tested for clean build and *very* *few* boards.

* Fix timer problems on AMCC yucca board.
  Set Timer Clock Select to use CPU clock as a timer input source.

* Bring yucca config more in line with other AMCC boards.

* Add AMCC bamboo board to MAKEALL build script.

* Fix AMCC bamboo eval board compilation errors.

* Add system memory to the PCI region list for AMCC PPC44x CPUs.
  Enabled it for Yucca board.

* Cleanup config file and bootup output for Yucca board.

* Fix CONFIG_440_GX define usage.

* Remove autogenerated bmp_logo.h file.

* Add support for AMCC 440SPe CPU based eval board (Yucca).

* Call serial_initialize() before first debug() is used.

* Cleanup trab board for GCC-4.x

* VoiceBlue update: use new MTD flash partitioning methods, use more
  reasonable TEXT_BASE, update default environment and enable keyed
  autoboot.
  Patch by Ladislav Michl, 16. Aug 2005

* Add forgotten changes for the PLEB 2 Board.
  Patch by David Snowdon, 13. Aug 2005

* Add support for wrPPMC7xx/74xx boards
  Patch by Richard Danter, 12 Aug 2005

* Add support for gth2 board
  Patch by Thomas Lange, Aug 11 2005

* Add support for CONFIG_SERIAL_MULTI on MPC5xxx
  Patch by Martin Krause, 8 Jun 2006

  This patch supports two serial consoles on boards with
  a MPC5xxx CPU. The console can be switched at runtime
  by setting stdin, stdout and stderr to the desired serial
  interface (serial0 or serial1). The PSCs to be used as
  console port are definded by CONFIG_PSC_CONSOLE
  and CONFIG_PSC_CONSOLE2.
  See README.serial_multi for details.

* 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.
  Patch by Martin Krause, 04 Apr 2006

* 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

* 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

  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?]
  Patch by Wolfgang Grandegger, 17 Jan 2006

* Correct GPIO setup (UART1/IRQ's) on yosemite & yellowstone

* OMAP 5912/OSK: update EMIFS CS1 timings:
  Problems have been seen in the linux kernel's smc91x network driver
  due to improper bus timings.  The latest 2.6 OMAP kernels currently
  have a workaround, but this fix belongs in u-boot.

  Patch by Alan J. Luse, 02 May 2006

* Scheduled for removal: strnicmp() which is unused

* Update for Intel Monahans boards:
  - support for magic key detection and handling on delta board
  - NAND support for zylonite board + some minor cleanup

* Declare load_serial_ymodem() when using CFG_CMD_LOADB.
  Patch by Jon Loeliger, 01 May 2006

* Fixed handling of bad checksums with "mkimage -l"

* 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.

  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
