2023-11-20crypto: ccp - Fix sample application signature passingMario Limonciello1-0/+1
[ Upstream commit 2ad01eb5fad24627ab4e196dc54a220753b2238b ] When parameters are sent the PSP returns back it's own signature for the application to verify the authenticity of the result. Display this signature to the caller instead of the one the caller sent.

2023-11-20crypto: ccp - Fix DBC sample application error handlingMario Limonciello1-8/+8
[ Upstream commit 70f242c1933e9e881c13c31640bb6d56e8b7e738 ] The sample application was taking values from ioctl() and treating those as the error codes to present to a user. This is incorrect when ret is non-zero, the error is stored to `errno`. Use this value instead.

2023-07-20crypto: ccp - Add a sample library for ioctl useMario Limonciello1-0/+72
Add a small shared library that demonstrates the usage of the IOCTL interface. This library can be linked to but, is intended to be loaded and used by higher level languages Acked-by: Tom Lendacky <thomas.lendacky@amd.com> Signed-off-by: Mario Limonciello <mario.limonciello@amd.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
