Change max size of uncompressed uImage's to 8MByte and add

[people/ms/u-boot.git] / CHANGELOG

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

* Change max size of uncompressed uImage's to 8MByte and add
  CFG_BOOTM_LEN to adjust this setting.

  As mentioned by Robin Getz on 2005-05-24 the size of uncompressed
  uImages was restricted to 4MBytes. This default size is now
  increased to 8Mbytes and can be overrided by setting CFG_BOOTM_LEN
  in the board config file.

  Patch by Greg Ungerer, 21 May 2005

* Word alignment fixes for word aligned NS16550 UART
  Patch by Jean-Paul Saman, 01 Mar 2005

  Fixes bug with UART that only supports word aligned access: removed
  "__attribute__ ((packed));" for "(CFG_NS16550_REG_SIZE == 4)" some
  (broken!) versions of GCC generate byte accesses when encountering
  the packed attribute regardless if the struct is already correctly
  aligned for a platform. Peripherals that can only handle word
  aligned access won't work properly when accessed with byte access.
  The struct NS16550 is already word aligned for REG_SIZE = 4, so
  there is no need to packed the struct in that case.

* Fix behaviour if gatewayip is not set
  Patch by Robin Gilks, 23 Dec 2004

  use hush shell.

* Convert mcc200 to use common CFI flash driver
  Patch by Stefan Roese, 28 Feb 2006

* Add env-variable "unlock" to handle initial state of sectors
  (locked/unlocked).

  Only the U-Boot image and it's environment is protected,
  all other sectors are unprotected (unlocked) if flash
  hardware protection is used (CFG_FLASH_PROTECTION) and
  the environment variable "unlock" is set to "yes".

  Patch by Stefan Roese, 28 Feb 2006

* Update drivers/cfi_flash.c:
  - find_sector() called in both versions of flash_write_cfiword()
  Patch by Peter Pearse, 27th Feb 2006

* CFI support for a x8/x16 AMD/Spansion flash configured in x8 mode
  Patch by Jose Maria Lopez, 16 Jan 2006

* Add support for AMD/Spansion Flashes in flash_write_cfibuffer
  Patch by Alex Bastos and Thomas Schaefer, 2005-08-29

* Changes/fixes for drivers/cfi_flash.c:
  We *should* check if there are any error bits if the previous call
  returned ERR_OK (Otherwise we will have output an error message in
  flash_status_check() already.)  The original code would only check for
  error bits if flash_status_check() returns ERR_TIMEOUT.
  Patch by Marcus Hall, 23 Aug 2005

* Changes/fixes for drivers/cfi_flash.c:
  - Add CFG_FLASH_PROTECT_CLEAR on drivers/cfi_flash.c
  - Prohibit buffer write when buffer_size is 1 on drivers/cfi_flash.c
  Patch by Sangmoon Kim, 19 Aug 2005

* Fixes for drivers/cfi_flash.c:
  - Fix wrong timeout value usage in flash_status_check()
  - Round write_tout up when converting to msec in flash_get_size()
  - Remove clearing flash status at the end of flash_write_cfibuffer()
    which sets Intel 28F640J3 flash back to command mode on CSB472
  Patch by Tolunay Orkun, 02 July 2005

* Add basic support for the SMMACO4 Board from PanDaCom.
  Patch by Heiko Schocher, 20 Feb 2006

* Add GIT version information (commid ID) to untagged U-Boot versions

  As done in the linux kernel, the U-Boot version (U_BOOT_VERSION)
  of all unreleased (untagged) U-Boot images will be automatically
  extended upon compiletime with a part of the GIT commit ID and
  possibly with "dirty" if uncommited changes are detected.

  Here an example for the resulting version:
  "U-Boot 1.1.4-g3457ac18-dirty"

  The version is now maintained in the toplevel Makefile and the
  version headers are autogenerated.

  Patch by Stefan Roese, 9 Feb 2006

  standard (as on PPC platforms), some messages with debug character
  are removed from the default U-Boot build.
  Enable DEBUG for lib_arm/board.c to enable debug messages.
  New CONFIG_DISPLAY_CPUINFO and CONFIG_DISPLAY_BOARDINFO options.
  Patch  by Stefan Roese, 24 Jan 2006

* Fix various compiler warnings on ppc4xx builds (ELDK 4.0)
  Patch by Stefan Roese, 18 Jan 2006

  Patch by Eugen Bigz, 19 Dec 2005

======================================================================
Changes for U-Boot 1.1.4:
======================================================================

* Changes to Yellowstone & Yosemite 440EP/GR eval boards:
  - Changed GPIO setup to enable another address line in order to
    address 64M of FLASH.
  - Added function sdram_tr1_set to auto calculate the tr1 value for
    the DDR.
  Patch by Steven Blakeslee, 12 Dec 2005

* MPC5200:  Set PCI retry counter to 0 = infinite retry;
  The default of 255 is too short for slow devices.
  Patch by Martin Nykodym, 12 Dec 2005

* Change port configuration for O2DNT (CODEC1 on PSC1).

* Fix register for PCI async mode on PPC440EP
  Patch by Youngchul Bang, 08 Dec 2005

* Fix U-Boot linking problems (add .eh_frame segment to linker script)
  This segment may be required by some libgcc.a functions
  (like _udivdi3).

* Fix DPRAM offset/size for MPC8541/8555.
  Simplify TQM85xx Makefile handling.

* Fix data overflow (typo?) in rtc/ds1302.c

* Fix U-Boot compilation for MIPS boards using ELDK 4.0

* Add support for TQM8541/8555 boards, TQM85xx support reworked:
  - Support for TQM8541/8555 boards added.
  - Complete rework of TQM8540/8560 support.
  - Common TQM85xx code now supports all current TQM85xx platforms
    (TQM8540/8541/8555/8560).
  - DDR SDRAM size detection added.
  - CAS latency default values can be overwritten by setting "serial#"
    to e.g. "ABC0001 casl=25" -> CAS latency 2.5 will be used.
    If problems are detected with this non default CAS latency,
    the default values will be used instead.
  - Flash size detection added.
  - Moved FCC ethernet driver initialization behind TSEC driver init
    -> TSEC is first device.
  Patch by Stefan Roese, 30 Nov 2005

* Add support for AMCC 440SP, add support for AMCC Luan 440SP eval board.
  Patch by John Otken, 23 Nov 2005

* Changed PPC44x startup message (cpu info, speed...) to common style:
  On PPC44x platforms, the startup message generated in "cpu.c" only
  comprised the ppc type and revision but not additional information
  like speed etc. Those speed infos where printed in the board specific
  code. This new implementation now prints all CPU infos in the common
  cpu specific code. No board specific code is needed anymore and
  therefore removed from all current 44x implementations.
  Patch by Stefan Roese, 27 Nov 2005

* Adjust TQM834x PHY addresses for latest hardware revision.

* Increase malloc arena on TQM5200 board to 256 kB.
  With 64 kb uniform flash sector size the old value of 128 kB was
  too small.

* Fix miiphy global data initialization (problem on 4xx boards when
  no ethaddr is assigned). Initialization moved from
  miiphy_register() to eth_initialize().

  Based on initial patch for 4xx platform by Matthias Fuchs.

* Remove unnnecessary #include <linux/types.h> from include/asm-*/u-boot.h

* Allow use of include/image.h and include/asm-*/u-boot.h in proprietary code.
  The COPYING file was extended to make clear that these files can be
  used in non-GPL code, too.
  Also, a corresponding note was placed in the headers of the affected files.

* Add support for Prodrive P3P440 board:
  - Added onboard PPC440 DDR autodetection in cpu/ppc/sdram.c
  - CFG_FLASH_QUIET_TEST added to use the common CFI driver
    for bank autodetection
  Patch by Stefan Roese, 22 Nov 2005

* Change all '$(...)' variable references into '${...}'
  which makes the environment compatible with the hush shell.
  WARNING: Support for the old '$(...)' syntax will be
  discontinued in a later version.

* Minor changes to init flags in TQM834x PCI.

* Fix Bamboo DDR SDRAM initialization (problem with onboard SDRAM)
  Patch by Stefan Roese, 15 Nov 2005

* New PPC 405EP board added: CMS700
  Added CONFIG_NET_MULTI for VOM405 board.
  Added reset_phy() for VOM405 board.
  Patch by Matthias Fuchs, 09 Nov 2005

  Patch by Stefan Roese, 07 Nov 2005

* Correct PPC Timebase register definitions (SPRN_TBRL...)
  Patch by Stefan Roese, 07 Nov 2005

  Patch by Stefan Roese, 01 Nov 2005

* Fix external IRQ configuration on Yellowstone & Yosemite
  Patch by Stefan Roese, 28 Oct 2005

* Add support for multiple PHYs.
  Tested on the following boards:
	cmcpu2      (at91rm9200/ether.c)
	PPChameleon (ppc4xx/4xx_enet.c)
	yukon       (mpc8220/fec.c)
	uc100       (mpc8xx/fec.c)
	tqm834x     (mpc834x/tsec.c) with EEPRO100
	lite5200    (mpc5xxx/fec.c) with EEPRO100 card (drivers/eepro100.c)
  Main changes include:
  common/miiphyutil.c
  - miiphy_register routine was added to allow multiple PHYs to be registered
  - miiphy_read and miiphy_write are now defined in this file, and
    require additional argument (char *devname)
  - other miiphy_* routines also require additional device name argument
  ../lib_i386/board.c
  ../lib_ppc/board.c
  Calling reset_phy() was moved to be executed *after* eth_initialize().
  This is necessary as now some of the implementations of reset_phy()
  may need to use miiphy_reset() which is not allowed before eth_initialize()
  as eth_initialize registers all required miiphy_* routines.
  Tested on IP860 and PHY initializes properly after this change.

  Patch by James MacAulay, 07 Oct 2005

* Eliminate hard-coded address of Ethernet transfer buffer on at91rm9200
  Patch by Anders Larsen, 07 Oct 2005

  The Atmel errata #11 states that the transfer buffer descriptor
  table must be aligned on a 16-word boundary. As it turned out, this
  is insufficient - it seems the table must be aligned on a boundary
  at least as large as the table itself (in Linux this is not an
  issue - the table is aligned on a PAGE_SIZE (4096) boundary).

* Fixed compilation for ARM when using a (standard) hard-FP toolchain
  Patch by Anders Larsen, 07 Oct 2005

* Fix warnings for PCI code on ixp
  Patch by Joe <lgxue@yahoo.com>, 13 Jan 2005

* virtex2 fix for bogus download error messages
  The virtex2 FPGA download code watches for init going active during
  a download of config data as an error condition. init also goes
  active after a configuration is finished in concert with the done
  signal. So far, the code does not check for done active until all
  of the configuration data is sent. If configuration data has a few
  extra pad bytes at the end, this would cause an error message even
  though the download had suceeded.
  NOTE: virtex2 slave serial and spartan2 versions may still have the
  same problem.

  Patch by Stefan Roese, 08 Aug 2005

* Fix compiler warnings with older GCC versions

* Add common (with Linux) MTD partition scheme and "mtdparts" command

  Old, obsolete and duplicated code was cleaned up and replace by the
  new partitioning method. There are two possible approaches now:

  The first one is to define a single, static partition:

  #undef CONFIG_JFFS2_CMDLINE
  #define CONFIG_JFFS2_DEV               "nor0"
  #define CONFIG_JFFS2_PART_SIZE         0xFFFFFFFF	/* use whole device */
  #define CONFIG_JFFS2_PART_SIZE         0x00100000	/* use 1MB */
  #define CONFIG_JFFS2_PART_OFFSET       0x00000000

  The second method uses the mtdparts command line option and dynamic
  partitioning:

  /* mtdparts command line support */
  #define CONFIG_JFFS2_CMDLINE
  #define MTDIDS_DEFAULT         "nor1=zuma-1,nor2=zuma-2"
  #define MTDPARTS_DEFAULT       "mtdparts=zuma-1:-(jffs2),zuma-2:-(user)"

  Command line of course produces bigger images, and may be inappropriate
  for some targets, so by default it's off.
