Detailed Description

RAM blob SUIT payload storage backends

RAM-based storage backend for SUIT OTA updates

Author: Koen Zandberg koen@.nosp@m.berg.nosp@m.zand..nosp@m.net

This module implements a RAM-backed storage interface for SUIT. The main purpose is mock testing the SUIT implementation, however the interface could also be used for to target backup ram storage by changing CONFIG_SUIT_STORAGE_RAM_SIZE to store it in backup ram.

The module uses a .ram.### structure where the number indicates the index of the memory region being targeted.

Warning: The install function is implemented as a noop. There is no distinction between valid content and not yet invalidated content.
