Merge patch series "aspeed: ast2700: Add Caliptra ECDSA driver"

Browse Source 
Chia-Wei Wang <chiawei_wang@aspeedtech.com> says:

Aspeed AST2700 SoCs integrates the Caliptra secure IP, where an ECDSA384
signature verification HW interface is exported for SoC crypto needs.

This patch series firstly extends the FIT image signing/verify common
code to support the ECDSA384 algorithm. For better convenience, the
device tree for ECDSA public key storage is also revised by referring
to RSA implementations.

After the FIT common code revision, the driver is implemented for
AST2700 to leverage the Caliptra ECDSA384 signature verification.

These are verified by signed FIT images with the algorithm "sha384,ecdsa384".
