Hi Amit Pundir,
I have a Poco F1 (EBBG) variant and I can confirm that the framebuffer address is same for the EBBG variant too.
I did a quick check by running the following command based on this link[1]:
xiber:~$ strings /dev/disk/by-partlabel/xbl_a | grep "Display Reserved"
0x9D400000, 0x02400000, "Display Reserved", AddMem, MEM_RES, SYS_MEM_CAP, Reserv, WRITE_BACK_XN
So I think it's safe to move this to sdm845-xiaomi-beryllium-common.dtsi
Regards, Joel Selvaraj
