<p dir="ltr">Hi Christian and Norman<br>
Thanks for the quick responses. So do you think it's fair to say that realistically 4MB is a probably the smallest you could do anything useful with. I know useful is hard to define.</p>

I did a quick check for foc_pbxa9 with the attached patch. The<br>
smallest working amount of RAM was 0x135000 (ca. 1.2 MiB), but this is<br>
without the RAM used by the Fiasco kernel in the scenario. From the<br>
Fiasco kernel debugger I got "Used 2445KB out of 16384KB of Kmem" with<br>
the command 'km'.<br>
<br>
Additionally, we have to add the amount of RAM used by ROM modules<br>
(currently loaded to RAM by the bootloader), which sums up to ca. 2.3<br>
MiB on foc_pbxa9.<br>
<br>
