CPU models are not typically prefixed with "LS", so "Loongson 3A4000/3A5000/3A6000".

Here is because when you do programming, variable name should prefix with letters.

Commit messages, comments, and log messages etc. are natural language, so it's better to treat them differently. No problem to keep code as-is IMO.

Also the description about the Loongson 2K series is a bit irrelevant (we're focusing on VRAM here) so you could simplify the sentence a bit.

We could reserve part of system RAM as VRAM for Loongson 2K series SoC.

Either reserved with 'of reserve memory' or  reserved by the firmware.


What's an "of reserve memory"? Is it "DeviceTree-reserved"?

The reserve ram will not accessible by kernel itself it this case, and can still be managed by ttm.

Of course. Feel free to tweak.
