-    tests: Avoid 64-bit arithmetic in assembler
-    
-    For testing we (ab)use the assembler to build us a sample dtb, independent
-    of the other tools (dtc and libfdt) that we're trying to test.  In a few
-    places this uses 64-bit arithmetic to decompose 64-bit constants into
-    the individual bytes in the blob.
-    
-    Unfortunately, it seems that some builds of GNU as don't support >32 bit
-    arithmetic, though it's not entirely clear to me which do and which don't
-    (Fedora i386 does support 64-bit, Debian arm32 doesn't).
-    
-    Anyway, to be safe, this avoids 64-bit arithmetic in assembler at the cost
-    of some extra awkwardness because we have to define the values in 32-bit
-    halves.
-

-    checks: Use proper format modifier for size_t
-    
-    The size of size_t can vary between architectures, so using %ld isn't
-    going to work on 32-bit builds. Use the %zu modifier to make sure it is
-    always correct.
