Is there a reason we can't do it all at compile time?

eg:

static const char * const test_data_4[] __initconst = {
#ifdef CONFIG_CPU_LITTLE_ENDIAN
"7bdb32be", "b293180a", "24c4ba70", "9b34837d",
"ad319ca6", "e9ac0f9c", "9919d14c", "0cafb143",
#else
"be32db7b", "0a1893b2", "70bac424", "7d83349b",
"a69c31ad", "9c0face9", "4cd11999", "43b1af0c",
#endif
};
