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

127 (These displays are serial and not suitable for using a normal
128 framebuffer console on them)
129 - add infrastructure needed in order to POST any DSPs in a board
130 - improve and fix various things in the MPC8xx FEC driver:
131 1. The new 87x and 88x series of processors have two FECs,
132 and the new driver supports them both.
133 2. Another change in the 87x/88x series is support for
134 the RMII (Reduced MII) interface. However numerous
135 changes are needed to make it work since the PHYs
136 are connected to the same lines. That means that
137 you have to address them correctly over the MII
139 3. We now correctly match the MII/RMII interface
140 configuration to what the PHY reports.
141 - Fix problem when readingthe MII status register. Due to the
142 internal design of many PHYs you have to read the register
143 twice. The problem is more apparent in 10Mbit mode.
144 - add new mode ".jffs2s" for reading from a NAND device: it just
145 skips over bad blocks.
146 - add networking support for VLANs (802.1q), and CDP (Cisco
148 - some minor patches / cleanup

1652 o correctly extends the timeout depending on the size of all
1653 queued messages for both transmit and receive
1654 o will not continue with receive if transmit times out
1655 o ensures that the error callback is done for all queued tx

1658 the callback, and does not overwrite an earlier error
1659 o logic in i2c_probe now correct
