Changes for U-Boot 1.1.4:
======================================================================
+* Cleanup
+
+* Update ARM Integrator boards:
+ Correct addessing errors in platform files.
+ Split off common core module data from Integrator header files to
+ include/armcoremodule.h.
+ Patch by Peter Pearse, 04 Oct 2005
+
* Make sure only supported compiler options are used
Import "cc-option" shell function from kernel and
use it to get the correct ARM GCC options for individual CPUs
Patch by Peter Pearse, 30 Jun 2005
* Fix 440GR to print correct cpu revision
- Patch by Stefan Roese, 4 Oct 2005
+ Patch by Stefan Roese, 04 Oct 2005
* Change board message on AMCC Yosemite & Yellowstone to common style
- Patch by Stefan Roese, 3 Oct 2005
+ Patch by Stefan Roese, 03 Oct 2005
* Fix compiler warning
