  314. * Update baudrate in bd_info when it gets changed
  315. * Add watchdog trigger points while waiting for serial port
  316. (so far only 8xx -- needed on LWMON with 100ms watchdog)
  317. * Improve command line tool to access the U-Boot's environment
  318. (figuration of the utility, using a config file)
  319. * Add single quote support for (old) command line parser
  320. * Switch LWMON board default config from FRAM to EEPROM;
  321. in POST, EEPROM shows up on 8 addresses
  322. ======================================================================
  323. Changes for U-Boot 0.2.0:
  324. ======================================================================
  325. * Use 1-byte-read instead of -write for iprobe() function
  326. Add i2c commands to PM826 config
  327. * extend I2C POST code: check for list on known addresses
  328. * Improve log buffer code; use "loglevel" to decide which messages
  329. to log on the console, too (like in Linux); get rid of "logstart"
  330. * Add command line tool to access the U-Boot's environment
  331. (board-specific for TRAB now, to be fixed later)

  363. (preliminary merge to U-Boot, still WIP)
  364. * Patch by Jon Diekema, 12 Nov 2002:
  365. - Adding URL for IEEE OUI lookup
  366. - Making the autoboot #defines dependent on CONFIG_AUTOBOOT_KEYED
  367. being defined.
  368. - In the CONFIG_EXTRA_ENV_SETTINGS #define, the root-on-initrd and
  369. root-on-nfs macros are designed to switch how the default boot
  370. method gets defined.
  371. * Patch by Daniel Engström, 13 Nov 2002:
  372. Add support for i386 architecture and AMD SC520 board

  376. Increase number of network RX buffers (PKTBUFSRX in
  377. "include/net.h") for EEPRO100 based boards (especially SP8240)
  378. which showed "Receiver is not ready" errors when U-Boot was
  379. processing the receive buffers slower than the network controller
  380. was filling them.
  381. * Patch by Andreas Oberritter, 09 Nov 2002:
  382. Change behaviour of NetLoop(): return -1 for errors, filesize
  383. otherwise; return code 0 is valid an means no file loaded - in this
  384. case the environment still gets updated!
  385. * Patches by Jon Diekema, 9 Nov 2002:
  386. - improve ADC/DAC clocking on the SACSng board to align
