+description: |
+  These bindings describe the STM32 SoCs ML-AHB interconnect bus which connects
+  a Cortex-M subsystem with dedicated memories. The MCU SRAM and RETRAM memory
+  parts can be accessed through different addresses (see "RAM aliases" in [1])
+  using different buses (see [2]): balancing the Cortex-M firmware accesses
+  among those ports allows to tune the system performance.
