+@deffn {Flash Driver} {npcx}
+All versions of the NPCX microcontroller families from Nuvoton include internal
+flash. The NPCX flash driver supports the NPCX family of devices. The driver
+automatically recognizes the specific version's flash parameters and
+autoconfigures itself. The flash bank starts at address 0x64000000.

+All members of the STM32 G0, G4, L4, L4+, L5, U5, WB and WL
microcontroller families from STMicroelectronics include internal flash
and use ARM Cortex-M0+, M4 and M33 cores.
The driver automatically recognizes a number of these chips using
The @var{num} parameter is a value shown by @command{flash banks}.

+@deffn Command {stm32l4x flashloader} num [@option{enable} | @option{disable}]
+Enables or disables the flashloader usage (enabled by default),
+when disabled it will fall back to direct memory access to program the Flash or OTP memories.
+if neither @option{enabled} nor @option{disable} are specified, the command will display
+the current configuration.

@deffn {Command} {stm32l4x mass_erase} num
Mass erases the entire stm32l4x device.
The @var{num} parameter is a value shown by @command{flash banks}.
Forces a re-load of the option byte registers. Will cause a system reset of the device.
The @var{num} parameter is a value shown by @command{flash banks}.

+@deffn Command {stm32l4x trustzone} num [@option{enable} | @option{disable}]
+Enables or disables Global TrustZone Security, using the TZEN option bit.
+If neither @option{enabled} nor @option{disable} are specified, the command will display
+the TrustZone status.
+@emph{Note:} This command works only with devices with TrustZone, eg. STM32L5.
+@emph{Note:} This command will perform an OBL_Launch after modifying the TZEN.
