Changes since U-Boot 0.2.2:
======================================================================
+* Patches by Robert Schwebel, 06 Mar 2003:
+ - fix bug in BOOTP code (must use NetCopyIP)
+ - update of CSB226 port
+ - clear BSS segment on XScale
+ - added support for i2c_init_board() function
+ - update to the Innokom plattform
+
+* Extend support for redundand environments for configurations where
+ environment size < sector size
+
* Patch by Rune Torgersen, 13 Feb 2003:
Add support for Motorola MPC8266ADS board
controls the rate of data transfer. The data rate thus
is 1 / (I2C_DELAY * 4).
+ CFG_I2C_INIT_BOARD
+
+ When a board is reset during an i2c bus transfer
+ chips might think that the current transfer is still
+ in progress. On some boards it is possible to access
+ the i2c SCLK line directly, either by using the
+ processor pin as a GPIO or by having a second pin
+ connected to the bus. If this option is defined a
+ custom i2c_init_board() routine in boards/xxx/board.c
+ is run early in the boot sequence.
