And how to configure the kernel to minimize the code modification ?
I am porting U-Boot and Linux to a new board with a MPC875 processor and two serial chips, and U-Boot runs well now. I hear that the FDT function can tell the kernel devices information more flexibly and reduce the code modification indirectly.
But I didn't find enough materials to make my head clear, so any tip is greatly appreciated.
Thanks.
Hi Gao,
I'm not up on 8xx, but it may not have been pulled forward into the "powerpc" architecture (still "ppc"). The "powerpc" architecture switch is where linux/u-boot started using the FDT.
I use U-Boot-V2009.8 and Linux-DENX-v2.6.30.3, and I can't find arch/ppc any more. So, I think FDT will work well in MPC8xx platform.
But I don't know how to use it, perhaps I shoud try the standard MPC885 configuration and dtb file.
Best regards, gvb
Thanks.
