/*
 * 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?
