Heiko Stuebner fdf0819afb rsa: fix alignment issue when getting public exponent ... To fill the exponent field of the rsa_public_key struct, rsa_mod_exp_sw did a cast to uint64_t of the key_prop->public_exponent field. But that alignment is not guaranteed in all cases. This came to light when in my spl-fit-signature the key-name exceeded a certain length and with it the verification then started failing. (naming it "integrity" worked fine, "integrity-uboot" failed) key_prop.public_exponent itself is actually a void-pointer, fdt_getprop() also just returns such a void-pointer and inside the devicetree the 64bit exponent is represented as 2 32bit numbers, so assuming a 64bit alignment can lead to false reads. So just use the already existing rsa_convert_big_endian() to do the actual conversion from the dt's big-endian to the needed uint64 value.
