Subject: [PATCH] bct_dump: don't crash on devices without RSA support
|
|
format_rsa_param() currently crashes on chips that don't implement
|
soc_config->get_value_size(); that is, on all chips before T124. Fix the
|
function not to crash. Better might be to avoid even dumping RSA
|
parameters on chips which don't support RSA, but that's a larger change
|
that needs much more work.
|
|
Fixes: 3c3b992a6814 ("Add support to dump rsa related fields for t210")
