This test verifies that ECDSA_UCLASS is implemented, and that ecdsa_verify() works as expected. The definition of "expected" is "does not find a device, and returns -ENODEV". The lack of a hardware-independent ECDSA implementation prevents us from having one in the sandbox, for now.

/*
|
|
* Basic test of the ECDSA uclass and ecdsa_verify()
|
|
*
|
|
* ECDSA implementations in u-boot are hardware-dependent. Until we have a
|
|
* software implementation that can be compiled into the sandbox, all we can
|
|
* test is the uclass support.
|
|
*
|
|
* The uclass_get() test is redundant since ecdsa_verify() would also fail. We
|
|
* run both functions in order to isolate the cause more clearly. i.e. is
|
|
* ecdsa_verify() failing because the UCLASS is absent/broken?
