  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?
