+# Remote Provisioning Changelog
+
+This document provides an exact description of which changes have occurred in the
+`IRemotelyProvisionedComponent` HAL interface in each Android release.
+
+## Releases
+* **Android S (12):** IRemotelyProvisionedComponent v1
+* **Android T (13):** IRemotelyProvisionedComponent v2
+
+## IRemotelyProvisionedComponent 1 -> 2
+* DeviceInfo
+ * Most entries are no longer optional.
+ * `att_id_state` is now `fused`. `fused` is used to indicate if SecureBoot is enabled.
+ * `version` is now `2`.
+ * `board` has been removed.
+ * `device` has been added.
+* RpcHardwareInfo
+ * `uniqueId` String added as a field in order to differentiate IRPC instances on device.

+     * different mode. Some HALs may only have a single mode, but an example where
+     * multiple modes would be required is if a chip has different firmwares with
+     * different capabilities.
+     *
+     * When in a mode, it must be possible to perform any combination of creating
+     * and removing interfaces as long as at least one of the
+     * ChipConcurrencyCombinations is satisfied. This means that if a chip has two
+     * available combinations, [{STA} <= 1] and [{AP_BRIDGED} <= 1] then it is expected
+     * that exactly one STA type or one AP_BRIDGED type can be created, but it

+     * was then there would be a single available combination
+     * [{STA} <=1, {AP_BRIDGED} <= 1].
+     *
+     * When switching between two available combinations it is expected that
+     * interfaces only supported by the initial combination must be removed until
+     * the target combination is also satisfied. At that point new interfaces
+     * satisfying only the target combination can be added (meaning the initial
+     * combination limits will no longer satisfied). The addition of these new
+     * interfaces must not impact the existence of interfaces that satisfy both
+     * combinations.
+     *
+     * For example, a chip with available combinations:
+     *     [{STA} <= 2, {NAN} <=1] and [{STA} <=1, {NAN} <= 1, {AP_BRIDGED} <= 1}]
+     * If the chip currently has 3 interfaces STA, STA and NAN and wants to add an
+     * AP_BRIDGED interface in place of one of the STAs, then one of the STA interfaces
+     * must be removed first, and then the AP interface can be created after
+     * the STA has been torn down. During this process the remaining STA and NAN
+     * interfaces must not be removed/recreated.
+     *
+     * If a chip does not support this kind of reconfiguration in this mode then
+     * the combinations must be separated into two separate modes. Before
+     * switching modes, all interfaces must be torn down, the mode switch must be
+     * enacted, and when it completes the new interfaces must be brought up.
