27 - add support for AtmarkTechno "suzaku" board
29 * Configure PPChameleon board to use redundand environment in flash
31 * Configure PPChameleon board to use JFFS2 NAND support.
33 * Added support for JFFS2 filesystem (read-only) on top of NAND flash
35 * Patch by Rune Torgersen, 16 Apr 2004:
38 * Patches by Pantelis Antoniou, 16 Apr 2004:
39 - add support for a new version of an Intracom board and fix
40 various other things on others.
41 - add verify support to the crc32 command (define
42 CONFIG_CRC32_VERIFY to enable it)
43 - fix FEC driver for MPC8xx systems:
44 1. fix compilation problems for boards that use dynamic
46 2. shut down FEC after network transfers
48 1. A new test command was added. This is a simplified version of
49 the one in the bourne shell.
50 2. A new exit command was added which terminates the current
52 3. Fixed handing of $? (exit code of last executed command)
53 - Fix some compile problems;
54 add "once" functionality for the netretry variable
56 * Patch by George G. Davis, 02 Apr 2004:
57 add support for Intel Assabet board
59 * Patch by Stephen Williams, 01 Apr 2004:

66 - add auto-complete support to the U-Boot CLI
67 - add support for NETTA and NETPHONE boards; fix NETVIA board
68 - add support for the Epson 156x series of graphical displays
69 (These displays are serial and not suitable for using a normal
70 framebuffer console on them)
71 - add infrastructure needed in order to POST any DSPs in a board
72 - improve and fix various things in the MPC8xx FEC driver:
73 1. The new 87x and 88x series of processors have two FECs,
74 and the new driver supports them both.
75 2. Another change in the 87x/88x series is support for
76 the RMII (Reduced MII) interface. However numerous
77 changes are needed to make it work since the PHYs
78 are connected to the same lines. That means that
79 you have to address them correctly over the MII
81 3. We now correctly match the MII/RMII interface
82 configuration to what the PHY reports.
83 - Fix problem when readingthe MII status register. Due to the
84 internal design of many PHYs you have to read the register
85 twice. The problem is more apparent in 10Mbit mode.
86 - add new mode ".jffs2s" for reading from a NAND device: it just
87 skips over bad blocks.
88 - add networking support for VLANs (802.1q), and CDP (Cisco
90 - some minor patches / cleanup
