128 - add verify support to the crc32 command (define
129 CONFIG_CRC32_VERIFY to enable it)
130 - fix FEC driver for MPC8xx systems:

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

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

1681 o correctly extends the timeout depending on the size of all
1682 queued messages for both transmit and receive
1683 o will not continue with receive if transmit times out
1684 o ensures that the error callback is done for all queued tx

1687 the callback, and does not overwrite an earlier error
1688 o logic in i2c_probe now correct

2315 (preliminary merge to U-Boot, still WIP)
2317 * Patch by Jon Diekema, 12 Nov 2002:
2318 - Adding URL for IEEE OUI lookup
2319 - Making the autoboot #defines dependent on CONFIG_AUTOBOOT_KEYED
2321 - In the CONFIG_EXTRA_ENV_SETTINGS #define, the root-on-initrd and
2322 root-on-nfs macros are designed to switch how the default boot
2323 method gets defined.
2325 * Patch by Daniel Engström, 13 Nov 2002:
2326 Add support for i386 architecture and AMD SC520 board
2328 * Patch by Pierre Aubert, 12 Nov 2002:
2329 Add support for DOS filesystem and booting from DOS floppy disk
2331 * Patch by Jim Sandoz, 07 Nov 2002:
2332 Increase number of network RX buffers (PKTBUFSRX in
2333 "include/net.h") for EEPRO100 based boards (especially SP8240)
2334 which showed "Receiver is not ready" errors when U-Boot was
2335 processing the receive buffers slower than the network controller
2338 * Patch by Andreas Oberritter, 09 Nov 2002:
2339 Change behaviour of NetLoop(): return -1 for errors, filesize
2340 otherwise; return code 0 is valid an means no file loaded - in this
2341 case the environment still gets updated!
2343 * Patches by Jon Diekema, 9 Nov 2002:
2344 - improve ADC/DAC clocking on the SACSng board to align
2345 the failing edges of LRCLK and SCLK
2346 - sbc8260 configuration tweaks
2347 - add status LED support for 82xx systems
2348 - wire sspi/sspo commands into command handler; improved error
2350 - add timestamp support and alternate memory test to the
2351 SACSng configuration
2353 * Patch by Vince Husovsky, 7 Nov 2002:
2354 Add "-n" to linker options to get rid of "Not enough room for
2355 program headers" problem
2357 * Patch by David Müller, 05 Nov 2002
2358 Rename CONFIG_PLL_INPUT_FREQ to CONFIG_SYS_CLK_FREQ
2359 so we can use an already existing name
2361 * Patch by Pierre Aubert, 05 Nov 2002
2362 Hardware relatied improvments in FDC boot code
2364 * Patch by Holger Schurig, 5 Nov 2002:
2365 Make the PXA really change it's frequency
2367 * Patch by Pierre Aubert, 05 Nov 2002
2368 Add support for slave serial Spartan 2 FPGAs
2370 * Fix uninitialized memory (MAC address) in 8xx SCC/FEC ethernet
2373 * Add support for log buffer which can be passed to Linux kernel's
2374 syslog mechanism; used especially for POST results.
2376 * Patch by Klaus Heydeck, 31 Oct 2002:
2377 Add initial support for kup4k board
2379 * Patch by Robert Schwebel, 04 Nov 2002:
2380 - use watchdog to reset PXA250 systems
2381 - added progress callbacks to (some of the) ARM code
2382 - update for Cogent CSB226 board
2384 * Add support for FPS860 board
2386 * Patch by Guillaume Alexandre,, 04 Nov 2002:
2387 Improve PCI access on 32-bits Compact PCI bus
2389 * Fix mdelay() on TRAB - this was still the debugging version with
2390 seconds instead of ms.
2392 * Patch by Robert Schwebel, 1 Nov 2002:
2393 XScale related cleanup (affects all ARM boards)
2395 * Cleanup of names and README.
