56 * Patch by Rune Torgersen, 16 Apr 2004:
59 * Patches by Pantelis Antoniou, 16 Apr 2004:
60 - add support for a new version of an Intracom board and fix
61 various other things on others.
62 - add verify support to the crc32 command (define
63 CONFIG_CRC32_VERIFY to enable it)
64 - fix FEC driver for MPC8xx systems:
65 1. fix compilation problems for boards that use dynamic
67 2. shut down FEC after network transfers
69 1. A new test command was added. This is a simplified version of
70 the one in the bourne shell.
71 2. A new exit command was added which terminates the current
73 3. Fixed handing of $? (exit code of last executed command)

87 - add auto-complete support to the U-Boot CLI
88 - add support for NETTA and NETPHONE boards; fix NETVIA board
89 - add support for the Epson 156x series of graphical displays
90 (These displays are serial and not suitable for using a normal
91 framebuffer console on them)
92 - add infrastructure needed in order to POST any DSPs in a board
93 - improve and fix various things in the MPC8xx FEC driver:
94 1. The new 87x and 88x series of processors have two FECs,
95 and the new driver supports them both.
96 2. Another change in the 87x/88x series is support for
97 the RMII (Reduced MII) interface. However numerous
98 changes are needed to make it work since the PHYs
99 are connected to the same lines. That means that
100 you have to address them correctly over the MII
102 3. We now correctly match the MII/RMII interface
103 configuration to what the PHY reports.
104 - Fix problem when readingthe MII status register. Due to the
105 internal design of many PHYs you have to read the register
106 twice. The problem is more apparent in 10Mbit mode.
107 - add new mode ".jffs2s" for reading from a NAND device: it just
108 skips over bad blocks.
109 - add networking support for VLANs (802.1q), and CDP (Cisco
111 - some minor patches / cleanup

591 * Patch by Anders Larsen, 09 Jan 2004:
593 ARM memory layout fixes: the abort-stack is now set up in the
594 correct RAM area, and the BSS is zeroed out as it should be.
596 Furthermore, the magic variables 'armboot_end' and 'armboot_end_data'
597 of the linker scripts are replaced by '__bss_start' and '_end',
598 resp., which is a further step to eliminate unnecessary differences
599 between the implementation of the CPU architectures.

1617 o will not continue with receive if transmit times out
1618 o ensures that the error callback is done for all queued tx
