2 Changes for U-Boot 1.1.1:
3 ======================================================================
5 * Patch by Rune Torgersen, 16 Apr 2004:
8 * Patches by Pantelis Antoniou, 16 Apr 2004:
9 - add support for a new version of an Intracom board and fix
10 various other things on others.
11 - add verify support to the crc32 command (define
12 CONFIG_CRC32_VERIFY to enable it)
13 - fix FEC driver for MPC8xx systems:
14 1. fix compilation problems for boards that use dynamic
16 2. shut down FEC after network transfers
18 1. A new test command was added. This is a simplified version of
19 the one in the bourne shell.
20 2. A new exit command was added which terminates the current
22 3. Fixed handing of $? (exit code of last executed command)
23 - Fix some compile problems;
24 add "once" functionality for the netretry variable
26 * Patch by George G. Davis, 02 Apr 2004:
27 add support for Intel Assabet board
29 * Patch by Stephen Williams, 01 Apr 2004:
30 Add support for Picture Elements JSE board
32 * Patch by Christian Pell, 01 Apr 2004:
33 Add CompactFlash support for PXA systems.
35 * Patches by Pantelis Antoniou, 30 Mar 2004:
36 - add auto-complete support to the U-Boot CLI
37 - add support for NETTA and NETPHONE boards; fix NETVIA board
38 - add support for the Epson 156x series of graphical displays
39 (These displays are serial and not suitable for using a normal
40 framebuffer console on them)
41 - add infrastructure needed in order to POST any DSPs in a board
42 - improve and fix various things in the MPC8xx FEC driver:
43 1. The new 87x and 88x series of processors have two FECs,
44 and the new driver supports them both.
45 2. Another change in the 87x/88x series is support for
46 the RMII (Reduced MII) interface. However numerous
47 changes are needed to make it work since the PHYs
48 are connected to the same lines. That means that
49 you have to address them correctly over the MII
51 3. We now correctly match the MII/RMII interface
52 configuration to what the PHY reports.
53 - Fix problem when readingthe MII status register. Due to the
54 internal design of many PHYs you have to read the register
55 twice. The problem is more apparent in 10Mbit mode.
56 - add new mode ".jffs2s" for reading from a NAND device: it just
57 skips over bad blocks.
58 - add networking support for VLANs (802.1q), and CDP (Cisco
60 - some minor patches / cleanup

1564 o correctly extends the timeout depending on the size of all
1565 queued messages for both transmit and receive
1566 o will not continue with receive if transmit times out
1567 o ensures that the error callback is done for all queued tx

1570 the callback, and does not overwrite an earlier error
1571 o logic in i2c_probe now correct
