+STM32MP1 Versions
+-----------------
+The STM32MP1 series is available in 3 different lines which are pin-to-pin compatible:
+
+- STM32MP157: Dual Cortex-A7 cores, Cortex-M4 core @ 209 MHz, 3D GPU, DSI display interface and CAN FD
+- STM32MP153: Dual Cortex-A7 cores, Cortex-M4 core @ 209 MHz and CAN FD
+- STM32MP151: Single Cortex-A7 core, Cortex-M4 core @ 209 MHz
+
+Each line comes with a security option (cryptography & secure boot) and a Cortex-A frequency option:
+
+- A Basic + Cortex-A7 @ 650 MHz
+- C Secure Boot + HW Crypto + Cortex-A7 @ 650 MHz
+- D Basic + Cortex-A7 @ 800 MHz
+- F Secure Boot + HW Crypto + Cortex-A7 @ 800 MHz
