L27.IS.X OMAP4 Icecream Sandwich HDCP steps

To use HDCP, the manufacturer must have his authorized HDCP key.

For OMAP4-ICS releases, HDCP keys are expected to be kept in /factory/hdcp.keys. A symbolic link is established between /factory/hdcp.keys & /system/vendor/firmware/hdcp.keys which is accessed to load it into key memory. This is a part of the init.omap4blazeboard.rc file: "symlink /factory/hdcp.keys /system/vendor/firmware/hdcp.keys"

When the board boots up, it looks for the key at this location and if found, it tries to enable the HDCP. In case of a failure it reports the same.

Repeater test:

For this, we need to run the test app "hdcp-test" once because this act loads the user space hdcp related library and that is required to do few HDCP processing related to repeater test cases. without this step, the repeater test cases would fail.
