79 various other things on others.
80 - add verify support to the crc32 command (define
81 CONFIG_CRC32_VERIFY to enable it)

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

107 - add support for the Epson 156x series of graphical displays
108 (These displays are serial and not suitable for using a normal
109 framebuffer console on them)
110 - add infrastructure needed in order to POST any DSPs in a board
111 - improve and fix various things in the MPC8xx FEC driver:
112 1. The new 87x and 88x series of processors have two FECs,
113 and the new driver supports them both.
114 2. Another change in the 87x/88x series is support for
115 the RMII (Reduced MII) interface. However numerous
116 changes are needed to make it work since the PHYs
117 are connected to the same lines. That means that
118 you have to address them correctly over the MII
120 3. We now correctly match the MII/RMII interface
121 configuration to what the PHY reports.
122 - Fix problem when readingthe MII status register. Due to the
123 internal design of many PHYs you have to read the register
124 twice. The problem is more apparent in 10Mbit mode.
125 - add new mode ".jffs2s" for reading from a NAND device: it just
126 skips over bad blocks.
127 - add networking support for VLANs (802.1q), and CDP (Cisco
129 - some minor patches / cleanup

611 ARM memory layout fixes: the abort-stack is now set up in the

1633 o correctly extends the timeout depending on the size of all
1634 queued messages for both transmit and receive
1635 o will not continue with receive if transmit times out
1636 o ensures that the error callback is done for all queued tx

1639 the callback, and does not overwrite an earlier error
1640 o logic in i2c_probe now correct

1905 Changed DHCP client to use IP address from server option field #54
1906 from the OFFER packet in the server option field #54 in the REQUEST
