139 - add support for a new version of an Intracom board and fix
140 various other things on others.
141 - add verify support to the crc32 command (define
142 CONFIG_CRC32_VERIFY to enable it)

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

168 - add support for the Epson 156x series of graphical displays
169 (These displays are serial and not suitable for using a normal
170 framebuffer console on them)
171 - add infrastructure needed in order to POST any DSPs in a board
172 - improve and fix various things in the MPC8xx FEC driver:
173 1. The new 87x and 88x series of processors have two FECs,
174 and the new driver supports them both.
175 2. Another change in the 87x/88x series is support for
176 the RMII (Reduced MII) interface. However numerous
177 changes are needed to make it work since the PHYs
178 are connected to the same lines. That means that
179 you have to address them correctly over the MII
181 3. We now correctly match the MII/RMII interface
182 configuration to what the PHY reports.
183 - Fix problem when readingthe MII status register. Due to the
184 internal design of many PHYs you have to read the register
185 twice. The problem is more apparent in 10Mbit mode.
186 - add new mode ".jffs2s" for reading from a NAND device: it just
187 skips over bad blocks.
188 - add networking support for VLANs (802.1q), and CDP (Cisco
190 - some minor patches / cleanup

1694 o correctly extends the timeout depending on the size of all
1695 queued messages for both transmit and receive
1696 o will not continue with receive if transmit times out
1697 o ensures that the error callback is done for all queued tx

1700 the callback, and does not overwrite an earlier error
1701 o logic in i2c_probe now correct

2321 Fix for natsemi NIC cards (DP83815)
2323 * Patch by Pierre Aubert, 19 Nov 2002:
2324 fix a bug for the MII configuration, and some warnings
2326 * Patch by Thomas Frieden, 13 Nov 2002:
2327 Add code for AmigaOne board
2328 (preliminary merge to U-Boot, still WIP)
2330 * Patch by Jon Diekema, 12 Nov 2002:
2331 - Adding URL for IEEE OUI lookup
2332 - Making the autoboot #defines dependent on CONFIG_AUTOBOOT_KEYED
2334 - In the CONFIG_EXTRA_ENV_SETTINGS #define, the root-on-initrd and
2335 root-on-nfs macros are designed to switch how the default boot
2336 method gets defined.
2338 * Patch by Daniel Engström, 13 Nov 2002:
2339 Add support for i386 architecture and AMD SC520 board
2341 * Patch by Pierre Aubert, 12 Nov 2002:
2342 Add support for DOS filesystem and booting from DOS floppy disk
2344 * Patch by Jim Sandoz, 07 Nov 2002:
2345 Increase number of network RX buffers (PKTBUFSRX in
2346 "include/net.h") for EEPRO100 based boards (especially SP8240)
2347 which showed "Receiver is not ready" errors when U-Boot was
2348 processing the receive buffers slower than the network controller
2351 * Patch by Andreas Oberritter, 09 Nov 2002:
2352 Change behaviour of NetLoop(): return -1 for errors, filesize
2353 otherwise; return code 0 is valid an means no file loaded - in this
2354 case the environment still gets updated!
2356 * Patches by Jon Diekema, 9 Nov 2002:
2357 - improve ADC/DAC clocking on the SACSng board to align
2358 the failing edges of LRCLK and SCLK
2359 - sbc8260 configuration tweaks
2360 - add status LED support for 82xx systems
2361 - wire sspi/sspo commands into command handler; improved error
2363 - add timestamp support and alternate memory test to the
2364 SACSng configuration
2366 * Patch by Vince Husovsky, 7 Nov 2002:
2367 Add "-n" to linker options to get rid of "Not enough room for
2368 program headers" problem
2370 * Patch by David Müller, 05 Nov 2002
2371 Rename CONFIG_PLL_INPUT_FREQ to CONFIG_SYS_CLK_FREQ
2372 so we can use an already existing name
2374 * Patch by Pierre Aubert, 05 Nov 2002
2375 Hardware relatied improvments in FDC boot code
2377 * Patch by Holger Schurig, 5 Nov 2002:

2383 * Fix uninitialized memory (MAC address) in 8xx SCC/FEC ethernet
2386 * Add support for log buffer which can be passed to Linux kernel's
2387 syslog mechanism; used especially for POST results.
2389 * Patch by Klaus Heydeck, 31 Oct 2002:
2390 Add initial support for kup4k board
2392 * Patch by Robert Schwebel, 04 Nov 2002:
2393 - use watchdog to reset PXA250 systems
2394 - added progress callbacks to (some of the) ARM code
2395 - update for Cogent CSB226 board
2397 * Add support for FPS860 board
2399 * Patch by Guillaume Alexandre,, 04 Nov 2002:
2400 Improve PCI access on 32-bits Compact PCI bus
2402 * Fix mdelay() on TRAB - this was still the debugging version with
2403 seconds instead of ms.
2405 * Patch by Robert Schwebel, 1 Nov 2002:
2406 XScale related cleanup (affects all ARM boards)
2408 * Cleanup of names and README.
