+ help
+ Use arm64 SIMD instructions (NEON) to parallelize two multiplications
+ in the modulus exponentiation algorithm, which speeds up RSA signature
+ verification in vboot. This is supported on all arm64 CPUs so you'd
+ generally always want this enabled, unless your SoC is overriding
+ vboot's hwcrypto API with its own crypto accelerator IP instead (or
+ you're trying really hard to save on code size).
