  1. ======================================================================
  2. Changes since U-Boot 0.2.1:
  3. ======================================================================
  4. * Patch by Stefan Roese, 13 Feb 2003:
  5. Add "pcidelay" environment variable (in ms, enabled via
  6. CONFIG_PCI_BOOTDELAY).
  7. PCI spec 2.2 defines, that a pci target has 2^25 pci clocks after
  8. RST# to respond to configuration cycles (33MHz -> 1s).

  16. 16 bytes out of each 32 byte block)
  17. ======================================================================
  18. Changes for U-Boot 0.2.1:
  19. ======================================================================
  20. * Add support for V37 board
  21. (patch by Jón Benediktsson, 11 Dec 2002)
  22. * Update baudrate in bd_info when it gets changed
  23. * Add watchdog trigger points while waiting for serial port
  24. (so far only 8xx -- needed on LWMON with 100ms watchdog)
  25. * Improve command line tool to access the U-Boot's environment
  26. (figuration of the utility, using a config file)
  27. * Add single quote support for (old) command line parser
  28. * Switch LWMON board default config from FRAM to EEPROM;
  29. in POST, EEPROM shows up on 8 addresses
  30. ======================================================================
  31. Changes for U-Boot 0.2.0:
  32. ======================================================================
  33. * Use 1-byte-read instead of -write for iprobe() function
  34. Add i2c commands to PM826 config
  35. * extend I2C POST code: check for list on known addresses
  36. * Improve log buffer code; use "loglevel" to decide which messages
  37. to log on the console, too (like in Linux); get rid of "logstart"
  38. * Add command line tool to access the U-Boot's environment
  39. (board-specific for TRAB now, to be fixed later)
  40. * Patch by Hans-Joerg Frieden, 06 Dec 2002

  70. Add code for AmigaOne board
  71. (preliminary merge to U-Boot, still WIP)
  72. * Patch by Jon Diekema, 12 Nov 2002:
  73. - Adding URL for IEEE OUI lookup
  74. - Making the autoboot #defines dependent on CONFIG_AUTOBOOT_KEYED
  75. being defined.
  76. - In the CONFIG_EXTRA_ENV_SETTINGS #define, the root-on-initrd and
  77. root-on-nfs macros are designed to switch how the default boot
  78. method gets defined.

  86. which showed "Receiver is not ready" errors when U-Boot was
  87. processing the receive buffers slower than the network controller
  88. was filling them.
  89. * Patch by Andreas Oberritter, 09 Nov 2002:
  90. Change behaviour of NetLoop(): return -1 for errors, filesize
