From 46a738a4ec81959c7545a4bb07e4f5232bbcfefe Mon Sep 17 00:00:00 2001 From: Alexandru Gagniuc Date: Thu, 29 Jul 2021 11:47:19 -0500 Subject: [PATCH] test: dm: Add test for ECDSA UCLASS support 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.
