[PATCH 1/1] lib: rsa: fix data abort in br_i32_decode()

After removing leading zeros the RSA modulus may be unaligned. On architectures like ARM 32bit unaligned access may lead to a data abort, e.g. when executing 'ut lib lib_asn1_pkcs7'. Use memcpy() to transfer from unaligned to aligned memory. Signed-off-by: Heinrich Schuchardt --- lib/rsa/rsa-ke
