  2. Changes for U-Boot 1.1.1:
  3. ======================================================================
  4. * Patches by Pantelis Antoniou, 30 Mar 2004:
  5. - add auto-complete support to the U-Boot CLI
  6. - add support for NETTA and NETPHONE boards; fix NETVIA board
  7. - add support for the Epson 156x series of graphical displays
  8. (These displays are serial and not suitable for using a normal
  9. framebuffer console on them)
  10. - add infrastructure needed in order to POST any DSPs in a board
  11. - improve and fix various things in the MPC8xx FEC driver:
  12. 1. The new 87x and 88x series of processors have two FECs,
  13. and the new driver supports them both.
  14. 2. Another change in the 87x/88x series is support for
  15. the RMII (Reduced MII) interface. However numerous
  16. changes are needed to make it work since the PHYs
  17. are connected to the same lines. That means that
  18. you have to address them correctly over the MII
  19. interface.
  20. 3. We now correctly match the MII/RMII interface
  21. configuration to what the PHY reports.
  22. - Fix problem when readingthe MII status register. Due to the
  23. internal design of many PHYs you have to read the register
  24. twice. The problem is more apparent in 10Mbit mode.
  25. - add new mode ".jffs2s" for reading from a NAND device: it just
  26. skips over bad blocks.
  27. - add networking support for VLANs (802.1q), and CDP (Cisco
  28. Discovery Protocol)

  1096. slightly different. see include/configs/hymod.h for an example

  1112. - 8260 i2c enhancement:
  1113. o correctly extends the timeout depending on the size of all
  1114. queued messages for both transmit and receive
  1115. o will not continue with receive if transmit times out
  1116. o ensures that the error callback is done for all queued tx
  1117. and rx messages
  1118. o correctly detects both tx and rx timeouts, only delivers one to
  1119. the callback, and does not overwrite an earlier error
  1120. o logic in i2c_probe now correct

  1593. processing the receive buffers slower than the network controller
  1594. was filling them.
  1595. * Patch by Andreas Oberritter, 09 Nov 2002:
  1596. Change behaviour of NetLoop(): return -1 for errors, filesize

  1598. case the environment still gets updated!
