1 ======================================================================
2 Changes since U-Boot 1.1.1:
3 ======================================================================
5 * Fix minor network problem on MPC5200: need some delay between
6 resetting the PHY and sending the first packet. Implemented in a
7 "natural" way by invoking the PHY reset and initialization code
8 only once after power on vs. each time the interface is brought up.
10 * Add some limited support for low-speed devices to SL811 USB controller
11 (at least "usb reset" now passes successfully and "usb info" displays
14 * Change init sequence for multiple network interfaces: initialize
15 on-chip interfaces before external cards.
17 * Fix memory leak in the NAND-specific JFFS2 code
19 * Fix SL811 USB controller when attached to a USB hub
21 * Fix config option spelling in PM520 config file
23 * Fix PHY discovery problem in cpu/mpc8xx/fec.c (introduced by
24 patches by Pantelis Antoniou, 30 Mar 2004)

29 - implement workaround for broken memory stick
30 - improve error handling
32 * Increase packet send timeout to 1 ms in cpu/mpc8xx/scc.c to better
33 cope with congested networks.

155 - add support for a new version of an Intracom board and fix
156 various other things on others.
157 - add verify support to the crc32 command (define
158 CONFIG_CRC32_VERIFY to enable it)

162 2. shut down FEC after network transfers
164 1. A new test command was added. This is a simplified version of
165 the one in the bourne shell.
166 2. A new exit command was added which terminates the current
168 3. Fixed handing of $? (exit code of last executed command)

184 - add support for the Epson 156x series of graphical displays
185 (These displays are serial and not suitable for using a normal
186 framebuffer console on them)
187 - add infrastructure needed in order to POST any DSPs in a board
188 - improve and fix various things in the MPC8xx FEC driver:
189 1. The new 87x and 88x series of processors have two FECs,
190 and the new driver supports them both.
191 2. Another change in the 87x/88x series is support for
192 the RMII (Reduced MII) interface. However numerous
193 changes are needed to make it work since the PHYs
194 are connected to the same lines. That means that
195 you have to address them correctly over the MII
197 3. We now correctly match the MII/RMII interface
198 configuration to what the PHY reports.
199 - Fix problem when readingthe MII status register. Due to the
200 internal design of many PHYs you have to read the register
201 twice. The problem is more apparent in 10Mbit mode.
202 - add new mode ".jffs2s" for reading from a NAND device: it just
203 skips over bad blocks.
204 - add networking support for VLANs (802.1q), and CDP (Cisco
206 - some minor patches / cleanup

1711 queued messages for both transmit and receive
1712 o will not continue with receive if transmit times out
1713 o ensures that the error callback is done for all queued tx

1716 the callback, and does not overwrite an earlier error
1717 o logic in i2c_probe now correct

2347 - Adding URL for IEEE OUI lookup
2348 - Making the autoboot #defines dependent on CONFIG_AUTOBOOT_KEYED
