Changes since U-Boot 1.1.4:
======================================================================
+* Add MCF5282 support (without preloader)
+ relocate ichache_State to ram
+ u-boot can run from internal flash
+ Add EB+MCF-EV123 board support.
+ Add m68k Boards to MAKEALL
+ Patch from Jens Scharsig, 08 Aug 2005
+
* MPC5200: enable snooping of DMA transactions on XLB even if no PCI
is configured; othrwise DMA accesses aren't cache coherent which
causes for example USB to fail.

-----------
To create U-Boot the gcc-2.95.3 compiler set (m68k-elf-20030314) from uClinux.org was used.
You can download it from: http://www.uclinux.org/pub/uClinux/m68k-elf-tools/
