+Subject: [PATCH 1/1] Fix cbfstool build error on GCC 15 host compiler
+
+GCC 15 now considers the unterminated-string-initialization warning as
+part of -Werror by default. Coreboot compiles host utilities with the
+system compiler, which results in getting this error in some files.
+
+Mark a hexadecimal translation table in cbfstool code as "nonstring" to
+avoid the warning-turned-error.
