Since the flash on STM32F4 is currently implemented as generic MappedMemory, all standard operations through the Flash CR silently fail. Attempting to write the Flash CR should trigger a more explicit warning log rather than the current debug log:

00:47:26.8846 [DEBUG] sysbus: Write value 0x80000000 to FLASH:CR (0x40023C10)

I suggest:

00:47:26.8846 [WARNING] sysbus: Write to FLASH:CR (0x40023C10) has no effect (Not Implemented)

Even better would be to implement the STM32 flash peripheral.

@franc0is We increased the verbosity of SVD-generated logs, and made them more explicit. STM32 flash is not currently on our roadmap, but I believe current logs will be more precise
