Why does the Portenta H7 prevent flashing directly into address 0x08000000?

Hi all,

I've followed the guide in the docs and however, when this runs it flashes the h7 chip at 0x08040000 instead of 0x08000000.

This is a bit different from the GIGA R1 Wifi, which can be flashed at 0x08000000 directly.

It's also referenced here, and if you check the build script, it uses this value as well in dfu-util

Thanks!
