> v3:
> * Fix printf warning by s/%ld/%zd/
> * Support plain "U" as an integer literal suffix
> * Fix misplaced semi-colons in grammar
> * Support integer expressions for /memreserve/ and /incbin/ too
> * Modify eval_literal to check U/L suffixes after strtoull call,
>   using strspn/strlen
> * Remove mention of libfdt from comment in tests/integer-expressions.c
> * Add comment to explain integer_prim range check
> v2:
> * s/cell/integer/ throughout.
> * Allow signed-extended values to pass the overall cell range check.
> * Allow L/UL/LL/ULL suffix on literals. This is purely for compatibility
