OK. Thanks for following me down this rabbit hole with a lamp.
That was fun!
I was expecting that shared memory could be more easilly and flexibly configured. But not so sure that this is productive now:-
- The U-Boot config controls the allocation of shared memory allocation of 32MB.
- To change that amount involves recompiling the whole bootloader.
- I'm in favour of minimal change to U-Boot board config to minimise the U-Boot Git hassle.
- The "memory" allocation in the device tree should be tidied/removed to avoid confusion (- or recognised by U-Boot which I can't see happening).
- Will update the thread on 'increased shared memory', maybe skin the cat another way.
