+Subject: [PATCH] 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.
