However, the driver incorrectly assumes that the list is strictly ordered and prematurely terminates traversal when it encounters an unrecognized type (>=BNGE_CTX_V2_MAX). As a result, any valid context types that appear later in the chain are silently skipped, leading to incomplete memory configuration and eventual driver load failure. Fix this by traversing the entire list until the BNGE_CTX_INV sentinel is reached, while safely ignoring only those context types that fall outside the supported range.

Remove it from the backing store configuration, as the firmware will not populate entities in this backing store type, due to which the driver load fails.
