1158 2. shut down FEC after network transfers
1159 - HUSH parser fixes:
1160 1. A new test command was added. This is a simplified version of
1161 the one in the bourne shell.
1162 2. A new exit command was added which terminates the current
1164 3. Fixed handing of $? (exit code of last executed command)
1165 - Fix some compile problems;
1166 add "once" functionality for the netretry variable

1177 * Patches by Pantelis Antoniou, 30 Mar 2004:
1178 - add auto-complete support to the U-Boot CLI
1179 - add support for NETTA and NETPHONE boards; fix NETVIA board
1180 - add support for the Epson 156x series of graphical displays
1181 (These displays are serial and not suitable for using a normal
1182 framebuffer console on them)
1183 - add infrastructure needed in order to POST any DSPs in a board
1184 - improve and fix various things in the MPC8xx FEC driver:
1185 1. The new 87x and 88x series of processors have two FECs,
1186 and the new driver supports them both.
1187 2. Another change in the 87x/88x series is support for
1188 the RMII (Reduced MII) interface. However numerous
1189 changes are needed to make it work since the PHYs
1190 are connected to the same lines. That means that
1191 you have to address them correctly over the MII
1193 3. We now correctly match the MII/RMII interface
1194 configuration to what the PHY reports.
1195 - Fix problem when readingthe MII status register. Due to the
1196 internal design of many PHYs you have to read the register
1197 twice. The problem is more apparent in 10Mbit mode.
1198 - add new mode ".jffs2s" for reading from a NAND device: it just
1199 skips over bad blocks.
1200 - add networking support for VLANs (802.1q), and CDP (Cisco
1202 - some minor patches / cleanup

2857 to "run var1 var2" where the contents of "var2" will NOT be
2858 executed when a command in "var1" fails.

2978 Changed DHCP client to use IP address from server option field #54
2979 from the OFFER packet in the server option field #54 in the REQUEST
