3 ======================================================================
5 * Fixes common/cmd_flash.c:
7 - fix some compiler/parser error, if using m68k tool chain
8 - optical fix for protect on/off all messages, if using more
10 Patch by Jens Scharsig, 28 July 2005
12 * Fix Lite5200B support: initialize SDelay register
13 See Freescale's AN3221 "MPC5200B SDRAM Initialization and
14 Configuration", 3.3.1 SDelay--MBAR + 0x0190
16 * Changes/fixes for drivers/cfi_flash.c:
18 - Add Intel legacy lock/unlock support to common CFI driver
20 On some Intel flash's (e.g. Intel J3) legacy unlocking is
21 supported, meaning that unlocking of one sector will unlock
22 all sectors of this bank. Using this feature, unlocking
23 of all sectors upon startup (via env var "unlock=yes") will
26 - Fixed problem with multiple reads of envronment variable
27 "unlock" as pointed out by Reinhard Arlt & Anders Larsen.

41 Patch by Anders Larsen, 31 Mar 2006
43 * Updates to common PPC4xx onboard (DDR)SDRAM init code (405 and 440)
45 405 SDRAM: - The SDRAM parameters can now be defined in the board
46 config file and the 405 SDRAM controller values will
47 be calculated upon bootup (see PPChameleonEVB).
48 When those settings are not defined in the board
49 config file, the register setup will be as it is now,
50 so this implementation should not break any current
51 design using this code.
53 Thanks to Andrea Marson from DAVE for this patch.
55 440 DDR: - Added function sdram_tr1_set to auto calculate the
56 TR1 value for the DDR.
57 - Added ECC support (see p3p440).

116 cpu/$(CPU)/$(SOC) directories
117 Patch by Andreas Engel, 13 Mar 2006
119 * Change max size of uncompressed uImage's to 8MByte and add
120 CFG_BOOTM_LEN to adjust this setting.
122 As mentioned by Robin Getz on 2005-05-24 the size of uncompressed
123 uImages was restricted to 4MBytes. This default size is now
124 increased to 8Mbytes and can be overrided by setting CFG_BOOTM_LEN
125 in the board config file.

199 Patch by Kumar Gala, 11 Jan 2006
201 * Added support for PCI prefetchable region and BARs
202 If a host controller sets up a region as prefetchable and
203 a device's BAR denotes it as prefetchable, allocate the
204 BAR into the prefetch region.
206 If a BAR is prefetchable and no prefetchable region has
207 been setup by the controller we fall back to allocating
208 the BAR into the normally memory region.

307 * Cleanup compiler warnings.
308 Patch by Greg Ungerer, 21 May 2005
310 * Word alignment fixes for word aligned NS16550 UART
311 Patch by Jean-Paul Saman, 01 Mar 2005
313 Fixes bug with UART that only supports word aligned access: removed
314 "__attribute__ ((packed));" for "(CFG_NS16550_REG_SIZE == 4)" some
315 (broken!) versions of GCC generate byte accesses when encountering
316 the packed attribute regardless if the struct is already correctly
317 aligned for a platform. Peripherals that can only handle word
318 aligned access won't work properly when accessed with byte access.
319 The struct NS16550 is already word aligned for REG_SIZE = 4, so
320 there is no need to packed the struct in that case.
322 * Fix behaviour if gatewayip is not set

334 (This is Work in Progress!)
336 * Add support for TQM8260-AI boards.
340 * Merge the new NAND code (testing-NAND brach); see doc/README.nand
341 Rewrite of NAND code based on what is in 2.6.12 Linux kernel
342 Patch by Ladislav Michl, 29 Jun 2005
344 * Add lowboot target to mcc200 board
345 Patch by Stefan Roese, 4 Mar 2006
347 * Fix problem with flash_get_size() from CFI driver update
348 Patch by Stefan Roese, 1 Mar 2006
350 * Make CFG_NO_FLASH work on ARM systems
351 Patch by Markus Klotzbuecher, 27 Feb 2006
353 * Update mcc200 config: Disable PCI and DoC, use 133 MHz IPB clock,
356 * Convert mcc200 to use common CFI flash driver
357 Patch by Stefan Roese, 28 Feb 2006
359 * Add env-variable "unlock" to handle initial state of sectors
362 Only the U-Boot image and it's environment is protected,
363 all other sectors are unprotected (unlocked) if flash
364 hardware protection is used (CFG_FLASH_PROTECTION) and
365 the environment variable "unlock" is set to "yes".
367 Patch by Stefan Roese, 28 Feb 2006
369 * Update drivers/cfi_flash.c:
370 - find_sector() called in both versions of flash_write_cfiword()
371 Patch by Peter Pearse, 27th Feb 2006
373 * CFI support for a x8/x16 AMD/Spansion flash configured in x8 mode

377 Patch by Alex Bastos and Thomas Schaefer, 2005-08-29
379 * Changes/fixes for drivers/cfi_flash.c:
380 We *should* check if there are any error bits if the previous call
381 returned ERR_OK (Otherwise we will have output an error message in
382 flash_status_check() already.) The original code would only check for
383 error bits if flash_status_check() returns ERR_TIMEOUT.
384 Patch by Marcus Hall, 23 Aug 2005
386 * Changes/fixes for drivers/cfi_flash.c:
387 - Add CFG_FLASH_PROTECT_CLEAR on drivers/cfi_flash.c
388 - Prohibit buffer write when buffer_size is 1 on drivers/cfi_flash.c
389 Patch by Sangmoon Kim, 19 Aug 2005
391 * Fixes for drivers/cfi_flash.c:
392 - Fix wrong timeout value usage in flash_status_check()
393 - Round write_tout up when converting to msec in flash_get_size()
394 - Remove clearing flash status at the end of flash_write_cfibuffer()
395 which sets Intel 28F640J3 flash back to command mode on CSB472
396 Patch by Tolunay Orkun, 02 July 2005
398 * Add basic support for the SMMACO4 Board from PanDaCom.
399 Patch by Heiko Schocher, 20 Feb 2006
401 * Add GIT version information (commid ID) to untagged U-Boot versions
403 As done in the linux kernel, the U-Boot version (U_BOOT_VERSION)
404 of all unreleased (untagged) U-Boot images will be automatically
405 extended upon compiletime with a part of the GIT commit ID and
406 possibly with "dirty" if uncommited changes are detected.
408 Here an example for the resulting version:
409 "U-Boot 1.1.4-g3457ac18-dirty"
411 The version is now maintained in the toplevel Makefile and the
412 version headers are autogenerated.
414 Patch by Stefan Roese, 9 Feb 2006
416 * Update default environment for INKA4x00 board.
418 * Convert CPCI750 to use common CFI flash driver
419 Patch by Reinhard Arlt, 8 Feb 2006
421 * Various changes to esd HH405 board specific files
422 Patch by Matthias Fuchs, 07 Feb 2006
424 * Cleanup U-Boot boot messages on ARM.
426 To match the U-Boot user interface on ARM platforms to the U-Boot
427 standard (as on PPC platforms), some messages with debug character
428 are removed from the default U-Boot build.
429 Enable DEBUG for lib_arm/board.c to enable debug messages.
430 New CONFIG_DISPLAY_CPUINFO and CONFIG_DISPLAY_BOARDINFO options.

487 - Support for TQM8541/8555 boards added.
488 - Complete rework of TQM8540/8560 support.
489 - Common TQM85xx code now supports all current TQM85xx platforms
490 (TQM8540/8541/8555/8560).
491 - DDR SDRAM size detection added.
492 - CAS latency default values can be overwritten by setting "serial#"
493 to e.g. "ABC0001 casl=25" -> CAS latency 2.5 will be used.
494 If problems are detected with this non default CAS latency,
495 the default values will be used instead.
496 - Flash size detection added.
497 - Moved FCC ethernet driver initialization behind TSEC driver init
498 -> TSEC is first device.
499 Patch by Stefan Roese, 30 Nov 2005
501 * Add support for AMCC 440SP, add support for AMCC Luan 440SP eval board.
502 Patch by John Otken, 23 Nov 2005
504 * Changed PPC44x startup message (cpu info, speed...) to common style:
505 On PPC44x platforms, the startup message generated in "cpu.c" only
506 comprised the ppc type and revision but not additional information
507 like speed etc. Those speed infos where printed in the board specific
508 code. This new implementation now prints all CPU infos in the common
509 cpu specific code. No board specific code is needed anymore and
510 therefore removed from all current 44x implementations.
511 Patch by Stefan Roese, 27 Nov 2005
513 * Adjust TQM834x PHY addresses for latest hardware revision.
515 * Increase malloc arena on TQM5200 board to 256 kB.
516 With 64 kb uniform flash sector size the old value of 128 kB was
519 * Fix miiphy global data initialization (problem on 4xx boards when
520 no ethaddr is assigned). Initialization moved from
521 miiphy_register() to eth_initialize().
523 Based on initial patch for 4xx platform by Matthias Fuchs.
525 * Remove unnnecessary #include <linux/types.h> from include/asm-*/u-boot.h
527 * Allow use of include/image.h and include/asm-*/u-boot.h in proprietary code.
528 The COPYING file was extended to make clear that these files can be
529 used in non-GPL code, too.
530 Also, a corresponding note was placed in the headers of the affected files.
532 * Add support for Prodrive P3P440 board:
533 - Added onboard PPC440 DDR autodetection in cpu/ppc/sdram.c
534 - CFG_FLASH_QUIET_TEST added to use the common CFI driver
535 for bank autodetection
536 Patch by Stefan Roese, 22 Nov 2005
538 * Change all '$(...)' variable references into '${...}'
539 which makes the environment compatible with the hush shell.
540 WARNING: Support for the old '$(...)' syntax will be
541 discontinued in a later version.
543 * Minor changes to init flags in TQM834x PCI.
545 * Fix Bamboo DDR SDRAM initialization (problem with onboard SDRAM)

570 Patch by Stefan Roese, 01 Nov 2005
572 * Fix external IRQ configuration on Yellowstone & Yosemite
573 Patch by Stefan Roese, 28 Oct 2005
575 * Add support for multiple PHYs.
576 Tested on the following boards:
577 cmcpu2 (at91rm9200/ether.c)
578 PPChameleon (ppc4xx/4xx_enet.c)
579 yukon (mpc8220/fec.c)
581 tqm834x (mpc834x/tsec.c) with EEPRO100
582 lite5200 (mpc5xxx/fec.c) with EEPRO100 card (drivers/eepro100.c)
583 Main changes include:
585 - miiphy_register routine was added to allow multiple PHYs to be registered
586 - miiphy_read and miiphy_write are now defined in this file, and
587 require additional argument (char *devname)
588 - other miiphy_* routines also require additional device name argument
591 Calling reset_phy() was moved to be executed *after* eth_initialize().
592 This is necessary as now some of the implementations of reset_phy()
593 may need to use miiphy_reset() which is not allowed before eth_initialize()
594 as eth_initialize registers all required miiphy_* routines.
595 Tested on IP860 and PHY initializes properly after this change.

655 * Eliminate hard-coded address of Ethernet transfer buffer on at91rm9200
656 Patch by Anders Larsen, 07 Oct 2005
658 The Atmel errata #11 states that the transfer buffer descriptor
659 table must be aligned on a 16-word boundary. As it turned out, this
660 is insufficient - it seems the table must be aligned on a boundary
661 at least as large as the table itself (in Linux this is not an
662 issue - the table is aligned on a PAGE_SIZE (4096) boundary).
664 * Fixed compilation for ARM when using a (standard) hard-FP toolchain

868 * Fix warnings for PCI code on ixp
869 Patch by Joe <lgxue@yahoo.com>, 13 Jan 2005
871 * virtex2 fix for bogus download error messages
872 The virtex2 FPGA download code watches for init going active during
873 a download of config data as an error condition. init also goes
874 active after a configuration is finished in concert with the done
875 signal. So far, the code does not check for done active until all
876 of the configuration data is sent. If configuration data has a few
877 extra pad bytes at the end, this would cause an error message even
878 though the download had suceeded.
879 NOTE: virtex2 slave serial and spartan2 versions may still have the

1109 Patch by Stefan Roese, 08 Aug 2005
1111 * Fix compiler warnings with older GCC versions
1113 * Add common (with Linux) MTD partition scheme and "mtdparts" command
1115 Old, obsolete and duplicated code was cleaned up and replace by the
1116 new partitioning method. There are two possible approaches now:
1118 The first one is to define a single, static partition:
1120 #undef CONFIG_JFFS2_CMDLINE
1121 #define CONFIG_JFFS2_DEV "nor0"
1122 #define CONFIG_JFFS2_PART_SIZE 0xFFFFFFFF /* use whole device */
1123 #define CONFIG_JFFS2_PART_SIZE 0x00100000 /* use 1MB */
1124 #define CONFIG_JFFS2_PART_OFFSET 0x00000000
1126 The second method uses the mtdparts command line option and dynamic
1129 /* mtdparts command line support */
1130 #define CONFIG_JFFS2_CMDLINE
1131 #define MTDIDS_DEFAULT "nor1=zuma-1,nor2=zuma-2"
1132 #define MTDPARTS_DEFAULT "mtdparts=zuma-1:-(jffs2),zuma-2:-(user)"
1134 Command line of course produces bigger images, and may be inappropriate
1135 for some targets, so by default it's off.

2605 - add support for a new version of an Intracom board and fix
2606 various other things on others.
2607 - add verify support to the crc32 command (define
2608 CONFIG_CRC32_VERIFY to enable it)

2633 - add support for NETTA and NETPHONE boards; fix NETVIA board
2634 - add support for the Epson 156x series of graphical displays
2635 (These displays are serial and not suitable for using a normal
2636 framebuffer console on them)
2637 - add infrastructure needed in order to POST any DSPs in a board
2638 - improve and fix various things in the MPC8xx FEC driver:
2639 1. The new 87x and 88x series of processors have two FECs,
2640 and the new driver supports them both.
2641 2. Another change in the 87x/88x series is support for
2642 the RMII (Reduced MII) interface. However numerous
2643 changes are needed to make it work since the PHYs
2644 are connected to the same lines. That means that
2645 you have to address them correctly over the MII
2647 3. We now correctly match the MII/RMII interface
2648 configuration to what the PHY reports.
2649 - Fix problem when readingthe MII status register. Due to the
2650 internal design of many PHYs you have to read the register
2651 twice. The problem is more apparent in 10Mbit mode.
2652 - add new mode ".jffs2s" for reading from a NAND device: it just
2653 skips over bad blocks.
2654 - add networking support for VLANs (802.1q), and CDP (Cisco
2656 - some minor patches / cleanup
