Subject: [RFC PATCH v3 1/6] crypto: ccp - rename psp-dev files to sev-dev
Date: Wed,  4 Dec 2019 11:48:58 +0530
Message-ID: <57c6797e99b1f62ff13222c8f0ee4687e8617a48.1575438845.git.Rijo-john.Thomas@amd.com> (raw)
In-Reply-To: <cover.1575438845.git.Rijo-john.Thomas@amd.com>

This is a preliminary patch for creating a generic PSP device driver
file, which will have support for both SEV and TEE (Trusted Execution
Environment) interface.

This patch does not introduce any new functionality, but simply renames
psp-dev.c and psp-dev.h files to sev-dev.c and sev-dev.h files
respectively.
