![]() In preparation for adding CQHCI crypto engine (inline encryption) support, add the code required to make mmc_core and mmc_block aware of inline encryption. Specifically: - Add a capability flag MMC_CAP2_CRYPTO to struct mmc_host. Drivers will set this if the host and driver support inline encryption. - Embed a blk_keyslot_manager in struct mmc_host. Drivers will initialize this (as a device-managed resource) if the host and driver support inline encryption. mmc_block registers this keyslot manager with the request_queue of any MMC card attached to the host. - Make mmc_block copy the crypto keyslot and crypto data unit number from struct request to struct mmc_request, so that drivers will have access to them. - If the MMC host is reset, reprogram all the keyslots to ensure that the software state stays in sync with the hardware state.
