Don't you see warnings for at25:

     89 (atmel,at25): 'size' is a required property
     89 (atmel,at25): 'pagesize' is a required property
     89 (atmel,at25): 'address-width' is a required property

These are due to using the deprecated (since 2012) at25,byte-len, 
at25,addr-mode, and at25,page-size properties. I think it has been long 
enough you can just replace them with the new ones.
