[PATCH v2 21/21] of: push struct boot_param_header and defines into powerpc

From: Rob Herring
Date: Tue Apr 22 2014 - 21:20:01 EST


From: Rob Herring <robh@xxxxxxxxxx>

Now powerpc is the only user of struct boot_param_header and FDT defines,
so they can be moved into the powerpc architecture code.
