1 ======================================================================
2 Changes for U-Boot 1.1.1:
3 ======================================================================
5 * Patches by Pantelis Antoniou, 30 Mar 2004:
6 - add auto-complete support to the U-Boot CLI
7 - add support for NETTA and NETPHONE boards; fix NETVIA board
8 - add support for the Epson 156x series of graphical displays
9 (These displays are serial and not suitable for using a normal
10 framebuffer console on them)
11 - add infrastructure needed in order to POST any DSPs in a board
12 - improve and fix various things in the MPC8xx FEC driver:
13 1. The new 87x and 88x series of processors have two FECs,
14 and the new driver supports them both.
15 2. Another change in the 87x/88x series is support for
16 the RMII (Reduced MII) interface. However numerous
17 changes are needed to make it work since the PHYs
18 are connected to the same lines. That means that
19 you have to address them correctly over the MII
21 3. We now correctly match the MII/RMII interface
22 configuration to what the PHY reports.

1526 o correctly extends the timeout depending on the size of all
1527 queued messages for both transmit and receive
1528 o will not continue with receive if transmit times out
1529 o ensures that the error callback is done for all queued tx

1532 the callback, and does not overwrite an earlier error
1533 o logic in i2c_probe now correct
