10  * Basic test of the ECDSA uclass and ecdsa_verify()
11  *
12  * ECDSA implementations in u-boot are hardware-dependent. Until we have a
13  * software implementation that can be compiled into the sandbox, all we can
14  * test is the uclass support.
15  *
16  * The uclass_get() test is redundant since ecdsa_verify() would also fail. We
17  * run both functions in order to isolate the cause more clearly. i.e. is
18  * ecdsa_verify() failing because the UCLASS is absent/broken?
