RAM size on qemu_x86

[mehrdadh]

Is it possible to increase RAM size on qemu_x86?
More information on this:
I run an qemu-system-i386 with 9MB RAM size. However, when I build my zephyr project I only have 3MB for RAM region. How can I increase 3MB?

adding more info:
I increased the size of RAM on qemu from 9MB to 20MB with "-m" flag, but that doesn't seem to change RAM region for zephyr project.

the closest thing that I found is here:
You can change DT_DRAM_SIZE to increase the RAM region. Not sure if this is exposed to the API.

I guess I answered my own question LoL.
