+Subject: [PATCH] vboot: Do not use hashed-strings offset
+
+The hashed-strings signature property includes two uint32_t values.
+The first is unneeded as there should never be a start offset into the
+strings region. The second, the size, is needed because the added
+signature node appends to this region.
+
+See tools/image-host.c, where a static 0 value is used for the offset.
