Hi Steven,

On 15/05/14 03:07, Steven King wrote:
Move the check for the QSPI config option inside the function body.  If the
option is not enabled, the compiler will optimize away the empty function
body so we can remove the other check for the config option.

These three Coldfire qspi patches look good to me.
I have added them to the for-next branch of the m68knommu git tree.

Thanks
Greg
