The build warnings are all of the "warning: -fstack-usage not supported for this target" kind also shown in this example.
I am sorry for stopping your hands. My patch causes this warning. It is already pointed by Tom, but merged accidentally. [PATCH v3] arm: bugfix: save_boot_params_default accesses uninitalized stack when -O0 http://lists.denx.de/pipermail/u-boot/2012-July/127693.html Please revert this to stop warnings.
I have posted the update patch. [PATCH v5] arm: bugfix: save_boot_params_default accesses uninitalized stack when -O0 http://lists.denx.de/pipermail/u-boot/2012-July/127844.html
Tom, Albert, please review my v5 patch.
