- Forbid curves with order less than 224 bits in ecc (FIPS 186-5)
- Add ECDSA NIST P521
Drivers:
- Expose otp zone in atmel
- Add dh fallback for primes > 4K in qat
- Add interface for live migration in qat
- Use dma for aes requests in starfive
- Add full DMA support for stm32mpx in stm32
- Add Tegra Security Engine driver
Others:
- Introduce scope-based x509_certificate allocation"
