u-boot/CHANGELOG

======================================================================
Changes since U-Boot 0.2.1:
======================================================================

* Patch by Stefan Roese, 18 Feb 2003:
  CPCIISER4 configuration updated.

* Patch by Stefan Roese, 17 Feb 2003:
  Fixed bug in ext. serial clock setup on PPC405 (since PPC440 port).

* Patch by Stefan Roese, 13 Feb 2003:
  Add "pcidelay" environment variable (in ms, enabled via
  CONFIG_PCI_BOOTDELAY).
  PCI spec 2.2 defines, that a pci target has 2^25 pci clocks after
  RST# to respond to configuration cycles (33MHz -> 1s).

* Patch by Stefan Roese, 10 Feb 2003:
  Add support for 4MB and 128MB onboard SDRAM (cpu/ppc4xx/sdram.c)

* Add dual ethernet support on PM826

* Add support for LXT971 PHY on PM826

* Patch by Tord Andersson, 16 Jan 2003:
  Fix flash sector count for TQM8xxL

* Fix I2C EEPROM problem on ICU862 board (would only write the first
  16 bytes out of each 32 byte block)

======================================================================
Changes for U-Boot 0.2.1:
======================================================================

* Add support for V37 board
  (patch by J<>n Benediktsson, 11 Dec 2002)

* Update baudrate in bd_info when it gets changed

* Add watchdog trigger points while waiting for serial port
  (so far only 8xx -- needed on LWMON with 100ms watchdog)

* Improve command line tool to access the U-Boot's environment
  (figuration of the utility, using a config file)

* Add single quote support for (old) command line parser

* Switch LWMON board default config from FRAM to EEPROM;
  in POST, EEPROM shows up on 8 addresses

======================================================================
Changes for U-Boot 0.2.0:
======================================================================

* Use 1-byte-read instead of -write for iprobe() function
  Add i2c commands to PM826 config

* extend I2C POST code: check for list on known addresses

* Improve log buffer code; use "loglevel" to decide which messages
  to log on the console, too (like in Linux); get rid of "logstart"

* Add command line tool to access the U-Boot's environment
  (board-specific for TRAB now, to be fixed later)

* Patch by Hans-Joerg Frieden, 06 Dec 2002
  Fix misc problems with AmigaOne support

* Patch by Chris Hallinan, 3 Dec 2002:
  minor cleanup to the MPC8245 EPIC driver

  Add support for external (SIU) interrupts on MPC8xx

* Patch by Pierre Aubert , 28 Nov 2002
  Fix nested syscalls bug in standalone applications

* Patch by David M<>ller, 27 Nov 2002:
  fix output of "pciinfo" command for CardBus bridge devices.

* Fix bug in TQM8260 board detection - boards got stuck when board ID
  was not readable

* Add LED indication for IDE activity on KUP4K board

* Fix startup problems with VFD display on TRAB

* Patch by Pierre Aubert, 20 Nov 2002
  Add driver for Epson SED13806 graphic controller.
  Add support for BMP logos in cfb_console driver.

* Added support for both PCMCIA slots (at the same time!) on MPC8xx

* Patch by Rod Boyce, 21 Nov 2002:
  fix PCMCIA on MBX8xx board

* Patch by Pierre Aubert , 21 Nov 2002
  Add CFG_CPM_POST_WORD_ADDR to make the offset of the
  bootmode word in DPRAM configurable

* Patch by Daniel Engstr<74>m, 18 Nov 2002:
  Fixes for x86 port (mostly strings issues)

* Patch by Ken Chou, 18 Nov 2002:
  Fix for natsemi NIC cards (DP83815)

* Patch by Pierre Aubert, 19 Nov 2002:
  fix a bug for the MII configuration, and some warnings

* Patch by Thomas Frieden, 13 Nov 2002:
  Add code for AmigaOne board
  (preliminary merge to U-Boot, still WIP)

* Patch by Jon Diekema, 12 Nov 2002:
  - Adding URL for IEEE OUI lookup
  - Making the autoboot #defines dependent on CONFIG_AUTOBOOT_KEYED
    being defined.
  - In the CONFIG_EXTRA_ENV_SETTINGS #define, the root-on-initrd and
    root-on-nfs macros are designed to switch how the default boot
    method gets defined.

* Patch by Daniel Engstr<74>m, 13 Nov 2002:
  Add support for i386 architecture and AMD SC520 board

* Patch by Pierre Aubert, 12 Nov 2002:
  Add support for DOS filesystem and booting from DOS floppy disk

* Patch by Jim Sandoz, 07 Nov 2002:
  Increase number of network RX buffers (PKTBUFSRX in
  "include/net.h") for EEPRO100 based boards (especially SP8240)
  which showed "Receiver is not ready" errors when U-Boot was
  processing the receive buffers slower than the network controller
  was filling them.

* Patch by Andreas Oberritter, 09 Nov 2002:
  Change behaviour of NetLoop(): return -1 for errors, filesize
  otherwise; return code 0 is valid an means no file loaded - in this
  case the environment still gets updated!

* Patches by Jon Diekema, 9 Nov 2002:
  - improve ADC/DAC clocking on the SACSng board to align
    the failing edges of LRCLK and SCLK
  - sbc8260 configuration tweaks
  - add status LED support for 82xx systems
  - wire sspi/sspo commands into command handler; improved error
    handlering
  - add timestamp support and alternate memory test to the
    SACSng configuration

* Patch by Vince Husovsky, 7 Nov 2002:
  Add "-n" to linker options to get rid of "Not enough room for
  program headers" problem

* Patch by David M<>ller, 05 Nov 2002
  Rename CONFIG_PLL_INPUT_FREQ to CONFIG_SYS_CLK_FREQ
  so we can use an already existing name

* Patch by Pierre Aubert, 05 Nov 2002
  Hardware relatied improvments in FDC boot code

* Patch by Holger Schurig, 5 Nov 2002:
  Make the PXA really change it's frequency

* Patch by Pierre Aubert, 05 Nov 2002
  Add support for slave serial Spartan 2 FPGAs

* Fix uninitialized memory (MAC  address)  in  8xx  SCC/FEC  ethernet
  drivers

* Add support for log buffer which can be passed to Linux kernel's
  syslog mechanism; used especially for POST results.

* Patch by Klaus Heydeck, 31 Oct 2002:
  Add initial support for kup4k board

* Patch by Robert Schwebel, 04 Nov 2002:
  - use watchdog to reset PXA250 systems
  - added progress callbacks to (some of the) ARM code
  - update for Cogent CSB226 board

* Add support for FPS860 board

* Patch by Guillaume Alexandre,, 04 Nov 2002:
  Improve PCI access on 32-bits Compact PCI bus

* Fix mdelay() on TRAB - this was still the debugging version with
  seconds instead of ms.

* Patch by Robert Schwebel, 1 Nov 2002:
  XScale related cleanup (affects all ARM boards)

* Cleanup of names and README.

Notes for U-Boot 0.1.0:
======================================================================

This is the initial version of "Das U-Boot", the Universal Boot Loader.

It is based on version 2.0.0 (the "Halloween Release") of PPCBoot.
