No, it doesn't work! Way back when the mmapped mode was stil in
flashboot ... then the program only wrote a few bytes here and there in
the area > 0x180000, so this doesn't work properly, like the datasheet
sais. Not all datasheets are false...
I'll have a look if it still works after your rework to the patch.
