That Bluetooth SMP knows about the private key is pointless, since the detection of debug key usage is actually via the public key portion. With this patch set, the Bluetooth SMP will stop keeping a copy of the ecdh private key, except when using debug keys. This way we let the crypto subsystem to generate and handle the ecdh private key, potentially benefiting of hardware ecc private key generation and retention. Tested with selftest and with btmon and smp-tester on top of hci_vhci, with ecdh done in both software and hardware (through atmel-ecc driver). All tests passed.
