-A platform integrator must provide a set of configuration data to configure how the block
-storage service provider presents block storage to clients. Configuration data relates to

-  - **Storage partition configuration** - determines how storage is divided into separate partitions
-  - **Block device configuration** - determines how the backed storage device is configured

+Block Store Devices
+-------------------
+
+  - **file_block_store** - stores blocks in file accessed using the standard C file (stdio.h) API.
+    The file represents a contiguous array of storage blocks. Designed to be used in a POSIX
+    environment as a virtual storage media.
+  - **fvb_block_store** - an adapter that uses a UEFI firmware volume block driver to access
+    storage. Can be used with drivers from the EDK2 project.
+  - **mock_block_store** - mocked block store for unit testing.
+  - **null_block_store** - a store with no real storage. Always accepts legal writes and returns
+    zeros for reads.
+  - **ram_block_store** - stores blocks in RAM. Intended for test purposes.
+  - **rpmb_block_store** - it is a Replay Protected Memory Block device
+    (see `SD Association home page`_) that uses the RPMB frontend to provide RPMB based storage.
+  - **semihosting_block_store** - it is a block device that can be used on emulators
+    (FVP, qemu, etc...) or on target platforms where the debugger can provide the file-system
+    semihosting features (See `this page`_.). Semihosting allows accessing files from the host
+    environment. This block store uses a single file to represent a contiguous array of storage
+    blocks.

-Some block devices supported in the TS project (located under:
-``components/service/block_storage/block_store/block_device``) are:
-
-  - **ram_block_store** - stores blocks in RAM. Intended for test purposes.
-  - **null_block_store** - a store with no real storage. Always accepts legal writes and returns
-    zeros for reads.
-  - **fvb_block_store** - an adapter that uses a UEFI firmware volume block driver to access
-    storage. Can be used with drivers from the EDK2 project.
-
-Other supported block_store components:
-
-  - **partitioned_block_store** - a stackable *block_store* that presents an underlying *block_store*
-    as a set of configurable storage partitions.
-  - **block_storage_client** - communicates with a remote block storage service provider to provide
-    storage.
+  - Block size of the store must be multiple of the AES block size (16 bytes).
+  - Encryption root key is currently a configurable vector in the future it should come from a
+    secure source, like from the Crypto SP or a separate SP responsible for root key storage and
+    key derivation, but in the current implementation
+  - AES with CBC block method encrypts a whole block, where the consecutive AES blocks are
+    interconnected. A drawback of this algorithm is that partial read or write does not
+    work. To mitigate this limitation at read request the whole block is read and only partial
+    data is returned, at write request the read-modify-write methodology is used.
