I’ve been trying to figure out why Xen only reports 2GB on my ARM

not familiar enough with the Xen code to fix it.
/dts-v1/;
/ {
model = "Broadcom STB (7445d0)";
compatible = "brcm,bcm7445d0", "brcm,brcmstb";
#address-cells = <0x2>;
#size-cells = <0x2>;
interrupt-parent = <0x1>;
memory {
#address-cells = <0x1>;
#size-cells = <0x1>;
device_type = "memory";
reg = <0x0 0x0 0x0 0x40000000 0x0 0x40000000 0x0 0x40000000>;
As said by David, Xen will parse "reg" using the #address-cells and
#size-cells of the parent. So it's normal to see 2GB. Does the same
device tree reports 3GB on Linux? I suspect no.
Although, what the rest of the node used for? Do we expect to parse it?
I wasn't able to find a suitable bindings in the docs...
