+Changes for U-Boot 0.4.7:
+======================================================================
+
+* Fix ICU862 environment problem
+
+* Fix RAM size detection for RMU board
+
+* Implement "reset" for MGT5100/MPC5200 systems

+======================================================================
+Changes for U-Boot 0.4.6:
======================================================================
* Make Ethernet autonegotiation on INCA-IP work for all clock rates;
* Patch by Richard Woodruff, 8 Aug 2003:
Allow crc32 to be used at address 0x000 (crc32_no_comp, too).
