Thanks for the reply. We were referring kuroboxHG.dts which uses Sandpoint architecture; which is almost same as ours.
1. one doubt in kuroboxHG is the ranges property in SOC node says EUMB is at 0xFC00_0000; and as per the datasheet of mpc107, the open pic address will be EUMB_BASE + 0x40000; but in kurobox its given as 0x80040000; 2. We know that our UART is mapped at address 0xDB00_0100; which is connected in a PCI-LOCAL bridge whose base is at 0xDB00_0000 How can i represent these things in dts ? Can the RANGES property of PCI node can mention this ?
