Changes since U-Boot 1.0.0:
======================================================================
+* Patch by Nicolas Lacressonnière, 12 Nov 2003:
+ update for for Atmel AT91RM9200DK development kit:
+ - support for environment variables in DataFlash
+ - Atmel DataFlash AT45DB1282 support
+
+* Patch by Jeff Carr, 11 Nov 2003:
+ add support for new version of 8270 processors
+
+* Patches by George G. Davis, 05 Nov 2003:
+ - only pass the ARM linux initrd tag to the kernel when an initrd
+ is actually present
+ - update omap1510inn configuration file
+
* Patches by Stephan Linz, 3 Nov 2003:
- more endianess fixes for LAN91C111 driver
- CFG_HZ configuration patch for NIOS Cyclone board
The size in bytes of the EEPROM device.
+- CFG_ENV_IS_IN_DATAFLASH:
+
+ Define this if you have a DataFlash memory device which you
+ want to use for the environment.
+
+ - CFG_ENV_OFFSET:
+ - CFG_ENV_ADDR:
+ - CFG_ENV_SIZE:
+
+ These three #defines specify the offset and size of the
+ environment area within the total memory of your DataFlash placed
+ at the specified address.
+
+
- CFG_SPI_INIT_OFFSET
Defines offset to the initial SPI buffer area in DPRAM. The
