[PATCH v1 0/8] Add ECDSA akcipher support and the ASPEED SBC ECDSA engine for AST10x0

This series adds ECDSA to the QEMU crypto akcipher framework and models the
ASPEED AST10x0 secure boot controller (SBC) ECDSA engine on top of it.

The crypto side adds ECDSA sign/verify for prime256v1 (NIST P-256) and
secp384r1 (NIST P-384) in both the gcrypt and nettle backends, using the raw
big-endian form (public key Qx || Qy, private key scalar d, signature r || s)
with a pre-computed digest as input.

Both the AST2600 and the AST1030/AST1060 have a Secure Boot Controller (SBC)
that supports RSA and ECDSA verification, but only the AST1030/AST1060 have an
ECDSA verify engine, so this series models ECDSA only. RSA verification is used
solely to verify the AST2600 SPL in ROM CODE, which ASPEED does not release,
so it is very unlikely to be used by end users.

v1:
 1. Add ECDSA akcipher support with gcrypt backend
 2. Add ECDSA akcipher support with nettle backend
 3. Add ECDSA sign/verify unit tests
 4. Support the ECDSA verify command for AST10x0
 5. Add ASPEED SBC ECDSA engine qtest
