569 o correctly extends the timeout depending on the size of all
570 queued messages for both transmit and receive
571 o will not continue with receive if transmit times out
572 o ensures that the error callback is done for all queued tx

1219 * Patch by Jim Sandoz, 07 Nov 2002:
1220 Increase number of network RX buffers (PKTBUFSRX in
1221 "include/net.h") for EEPRO100 based boards (especially SP8240)
1222 which showed "Receiver is not ready" errors when U-Boot was
1223 processing the receive buffers slower than the network controller
1226 * Patch by Andreas Oberritter, 09 Nov 2002:
1227 Change behaviour of NetLoop(): return -1 for errors, filesize
1228 otherwise; return code 0 is valid an means no file loaded - in this
1229 case the environment still gets updated!
1231 * Patches by Jon Diekema, 9 Nov 2002:
1232 - improve ADC/DAC clocking on the SACSng board to align
1233 the failing edges of LRCLK and SCLK
1234 - sbc8260 configuration tweaks
1235 - add status LED support for 82xx systems
1236 - wire sspi/sspo commands into command handler; improved error
1238 - add timestamp support and alternate memory test to the
1239 SACSng configuration
1241 * Patch by Vince Husovsky, 7 Nov 2002:
1242 Add "-n" to linker options to get rid of "Not enough room for
1243 program headers" problem
1245 * Patch by David Müller, 05 Nov 2002
1246 Rename CONFIG_PLL_INPUT_FREQ to CONFIG_SYS_CLK_FREQ
1247 so we can use an already existing name
1249 * Patch by Pierre Aubert, 05 Nov 2002
1250 Hardware relatied improvments in FDC boot code
1252 * Patch by Holger Schurig, 5 Nov 2002:

1258 * Fix uninitialized memory (MAC address) in 8xx SCC/FEC ethernet
1261 * Add support for log buffer which can be passed to Linux kernel's
1262 syslog mechanism; used especially for POST results.
1264 * Patch by Klaus Heydeck, 31 Oct 2002:
1265 Add initial support for kup4k board
1267 * Patch by Robert Schwebel, 04 Nov 2002:
1268 - use watchdog to reset PXA250 systems
1269 - added progress callbacks to (some of the) ARM code
1270 - update for Cogent CSB226 board
1272 * Add support for FPS860 board
1274 * Patch by Guillaume Alexandre,, 04 Nov 2002:
1275 Improve PCI access on 32-bits Compact PCI bus
1277 * Fix mdelay() on TRAB - this was still the debugging version with
1278 seconds instead of ms.
1280 * Patch by Robert Schwebel, 1 Nov 2002:
1281 XScale related cleanup (affects all ARM boards)
1283 * Cleanup of names and README.
