nope. I just want a method to adjust the size of the internal ram & flash, 
existing inside the MCU, sizes currently hard-wired in the QEMU definitions of 
a given MCU.

the point is that there are thousand of different Cortex-M MCUs, and unless we 
define a mechanism for QEMU to read the CMSIS xml definitions and 
auto-magically provide emulated devices with exactly the vendor specifications, 
there will always be some users in need of a MCU that is not present in QEMU, 
but might have a close relative already implemented, the difference between the 
two being in ram and/or flash size.

so, for such cases, where would be more appropriate to define the ram/flash 
sizes? -machine is definitely not the right place, -cpu seems also not 
appropriate, what else do we have left?
