configuration/config-txt/memory.md - minor fixup

[ghost]

There's an 8GB Pi 4 now. Reword things slightly, and don't enumerate each model of Pi 4. The intention is to make the opening paragraph read simpler, and perhaps make future maintenance of the page slightly easier.

I'd be inclined to really emphasise that the use of large values for gpu_mem can actually stop the device booting, also emphasis that increasing it does NOT increase performance.

I've address the review comments. The page says the default is 64 but on my systems I'm seeing a default of 76MB now, but I'm not sure if this is Pi 4-specific.

[ghost]

OK, this one should be ready to roll now, except for the query re default.

It seems the default is now 76MB on all devices. I've filed RPi-Distro/raspi-config#122 to have raspi-config fixed accordingly.

Actually it's just Pi 2 and later. I don't have a Zero to hand to test, but from memory it is 64MB on that as well.

LGTM @lurch?

Might be useful to get feedback from @spl237 or @popcornmix about the default gpu_mem value?

Good idea. Is there a 1GB Pi 1? It might be related to memory size rather than SoC.

[popcornmix]

There are no 1GB Pi0/Pi1 devices.

[popcornmix]

default gpu_mem is 76 for 1GB (or greater) and 64 for less.

Thanks for the clarification. The page should now be ready to go.
