Enable block storage service for N1SDP
To enable feature development using the Block Storage SP as a backing store, add a recipe (ts-sp-block-storage) to build the Block Storage secure partition. Conditionally add it to OP-TEE using a new machine feature (ts-block-storage).
For the N1SDP only, enable the Block Storage secure partition.
Note: The Block Storage SP must be loaded before any SP which uses it.
