Hi Rob,
I am seeing some warning in juno DTS files. I would like to get your
feedback on how to resolve them.
Warning messages:
Warning (simple_bus_reg): Node /smb@8000000/motherboard/flash@0,00000000
simple-bus unit address format error, expected "0"
Warning (simple_bus_reg): Node
/smb@8000000/motherboard/ethernet@2,00000000 simple-bus unit address
format error, expected "200000000"
Warning (simple_bus_reg): Node
/smb@8000000/motherboard/iofpga@3,00000000 simple-bus unit address
format error, expected "300000000"
We have
smb@8000000 {
compatible = "simple-bus";
#address-cells = <2>;
#size-cells = <1>;
ranges = <0 0 0 0x08000000 0x04000000>,
<1 0 0 0x14000000 0x04000000>,
<2 0 0 0x18000000 0x04000000>,
<3 0 0 0x1c000000 0x04000000>,
<4 0 0 0x0c000000 0x04000000>,
<5 0 0 0x10000000 0x04000000>;
...
flash@0,00000000 {
...
};
ethernet@2,00000000 {
...
};
iofpga@3,00000000 {
...
};
};
All of which are @offset 0x0 in their respective ranges.
How do we specify the range as well as the offset ? Does the below
look like correct way of fixing those warnings ?
flash@0
ethernet@200000000
iofpga@300000000
Or can I ignore these warning as I see the syntax to be correct as
provided in example in ePAPR(page 99 under Appendix B1 Ebony Device
Tree). Sorry if I have missed to follow any other thread on the same.
