- changes for v2:
  - fix EEprom_ivm setting for km82xx boards
  - adapted README
  - rebase against current mainline 178d0cc1a4c73c3341afbeb2a93b172de8c96bd1
  - pass i2c_adapter struct to i2c_core callbacks
    suggested by Stephen Warren and Simon Glass.
- changes for v3:
  - adapt to the new introduced U_BOOT_I2C_ADAP_COMPLETE define
  - added README entry
  - patch has 2 different checkpatch warnings:
WARNING: Use of volatile is usually wrong: see Documentation/volatile-considered-harmful.txt
+#  define I2C_SOFT_DECLARATIONS volatile ioport_t *iop = \
WARNING: Avoid CamelCase: <pFIO_DIR>
+#define I2C_INIT		(*pFIO_DIR |=  PF_SCL); asm("ssync;")
    This should be fixed in a seperate step, as it affects a lot
    of boards...
