ecc_hardware_Accelerator_P: Same as before but with a prime field, a constant-time ladder, and an AXI4-Lite bus
Porting a binary-field elliptic curve scalar multiplier to P-256 turned into three separate projects: a prime-field rebuild of the same architecture, a parallel-multiplier constant-time Montgomery ladder, and an AXI4-Lite peripheral to put it on a bus.
