 * Sha256dt: unoptimized is working, SHA2 is enabled but untested, 4way is disabled.
 * Blake2s: unoptimized is working.
-* x17: working with Blake linear SIMD, Keccak 2way and Cubehash linear SIMD. Shavite AES is enabled and compiles but untested. all other optimizations are disabled.

 * CPU and SW feature detection and reporting is working, algo features in progress, CPU brand not yet implemented.
 * CPU temperature and clock frequency is working.
 * cpu-affinity & thhreads are working.
 
 Known problems:
+* Sha256 & sha512 Parallel N-way are disabled. They work fine on X86_64. 
 * Simd: Multiple issues with NEON, affects x* algos performance. 
 * SWIFFTX: Multiple issues with NEON, affects x22i & x25x.
 * Lyra2 algos including allium, phi2, x22i & x25x are not working.
