All previous raspi machines can be created using the generic machine. Deprecate the old names to maintain a single one. Update the tests.

This is not how we typically handle "we have a bunch of different devboards in one family". What's wrong with the existing set of machine names?
Zoltan and you don't want to add more machine names, then you don't want a generic machine. This is very confusing.
IMHO we can have distinct machines for each model, but *NOT* have further machines for each RAM size within a model.
Yes, this was what I was intending to suggest. Apologies if I was confusing with what I said the previous time round.
OK, let's see if we understand each other correctly as developer, before explaining to users, taking the 4B model as example. The 4B come in 4 physical variants, depending on the amount of DRAM: 1G, 2G, 4G and 8G. We can not allocate 2G on 32-bit hosts, so to have a reproducible guest behavior on 32/64-bit hosts, it makes sense to takes the model with 1G of DRAM as default for the 'raspi4b' machine. If an user specify -m 2G ... 8G, we can adapt the 'board_rev' register to expose the corresponding amount of ram. Now, how / where to tell the users 1/ the default is 1G, and 2/ they can use 2/4/8G?
