Define a UCLASS API for verifying ECDSA signatures. Unlike UCLASS_MOD_EXP, which focuses strictly on modular exponentiation, the ECDSA class focuses on verification. This is done so that it better aligns with mach-specific implementations, such as stm32mp.

This needs a test, as do all uclasses in U-Boot. If it isn't easy to implement the algorithm then I suppose you could fake it by using an easy algorithm like md5, but it does need a test.
I agree. I couldn't find a test for UCLASS_MOD_EXP (for guidance), so I'm not sure where to even start.
