210 2. shut down FEC after network transfers

233 (These displays are serial and not suitable for using a normal
234 framebuffer console on them)
235 - add infrastructure needed in order to POST any DSPs in a board
236 - improve and fix various things in the MPC8xx FEC driver:
237 1. The new 87x and 88x series of processors have two FECs,
238 and the new driver supports them both.
239 2. Another change in the 87x/88x series is support for
240 the RMII (Reduced MII) interface. However numerous
241 changes are needed to make it work since the PHYs
242 are connected to the same lines. That means that
243 you have to address them correctly over the MII
245 3. We now correctly match the MII/RMII interface
246 configuration to what the PHY reports.
247 - Fix problem when readingthe MII status register. Due to the
248 internal design of many PHYs you have to read the register
249 twice. The problem is more apparent in 10Mbit mode.
250 - add new mode ".jffs2s" for reading from a NAND device: it just
251 skips over bad blocks.
252 - add networking support for VLANs (802.1q), and CDP (Cisco
254 - some minor patches / cleanup

1757 - 8260 i2c enhancement:
1758 o correctly extends the timeout depending on the size of all
1759 queued messages for both transmit and receive
1760 o will not continue with receive if transmit times out
1761 o ensures that the error callback is done for all queued tx
1763 o correctly detects both tx and rx timeouts, only delivers one to
1764 the callback, and does not overwrite an earlier error
1765 o logic in i2c_probe now correct

2315 * Add support for V37 board
2316 (patch by Jón Benediktsson, 11 Dec 2002)
2318 * Update baudrate in bd_info when it gets changed
2320 * Add watchdog trigger points while waiting for serial port
2321 (so far only 8xx -- needed on LWMON with 100ms watchdog)
2323 * Improve command line tool to access the U-Boot's environment
2324 (figuration of the utility, using a config file)
2326 * Add single quote support for (old) command line parser
2328 * Switch LWMON board default config from FRAM to EEPROM;
2329 in POST, EEPROM shows up on 8 addresses
2331 ======================================================================
2332 Changes for U-Boot 0.2.0:
2333 ======================================================================
2335 * Use 1-byte-read instead of -write for iprobe() function
2336 Add i2c commands to PM826 config
2338 * extend I2C POST code: check for list on known addresses
2340 * Improve log buffer code; use "loglevel" to decide which messages
2341 to log on the console, too (like in Linux); get rid of "logstart"
2343 * Add command line tool to access the U-Boot's environment
2344 (board-specific for TRAB now, to be fixed later)

2390 * Patch by Thomas Frieden, 13 Nov 2002:
2391 Add code for AmigaOne board
2392 (preliminary merge to U-Boot, still WIP)
2394 * Patch by Jon Diekema, 12 Nov 2002:
2395 - Adding URL for IEEE OUI lookup
2396 - Making the autoboot #defines dependent on CONFIG_AUTOBOOT_KEYED
2398 - In the CONFIG_EXTRA_ENV_SETTINGS #define, the root-on-initrd and
2399 root-on-nfs macros are designed to switch how the default boot
2400 method gets defined.
2402 * Patch by Daniel Engström, 13 Nov 2002:

2405 * Patch by Pierre Aubert, 12 Nov 2002:

2408 * Patch by Jim Sandoz, 07 Nov 2002:
2409 Increase number of network RX buffers (PKTBUFSRX in
2410 "include/net.h") for EEPRO100 based boards (especially SP8240)
2411 which showed "Receiver is not ready" errors when U-Boot was
2412 processing the receive buffers slower than the network controller
2415 * Patch by Andreas Oberritter, 09 Nov 2002:
2416 Change behaviour of NetLoop(): return -1 for errors, filesize
2417 otherwise; return code 0 is valid an means no file loaded - in this
2418 case the environment still gets updated!

2424 - add status LED support for 82xx systems
2425 - wire sspi/sspo commands into command handler; improved error

2428 SACSng configuration

2431 Add "-n" to linker options to get rid of "Not enough room for
2432 program headers" problem
2434 * Patch by David Müller, 05 Nov 2002
2435 Rename CONFIG_PLL_INPUT_FREQ to CONFIG_SYS_CLK_FREQ
