+
+    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.
