All, Sorry for my ignorance here, but we have upgraded our kernel from 2.6.11.xx to 2.6.20-rcx (using a specific git-branch for the mpc85xx) to run on the MPC8548CDS eval board (using default options provided by this branch for this eval board). I successfully compiled/loaded the uImage, but it hangs after decompression (with root=/dev/nfs)
Also, I was told to upgrade our u-boot source code (with another git branch for to the mpc85xx) and successfully get to the u-boot prompt. >From googling through the lists - it seems that I need to build a device tree blob and pass that device tree to the kernel in some fashion? I tried to compile the default dts image (using the dtc compiler installed by LTIB), but it is complaining about no '/chosen' in the definition: <path>/dtc -I dts -O dtb - -o mpc8548cds.dtb -V 16 dts/mpc8548cds.dts I've looked at the Documentation/powerpc/booting_without_of.txt, and this gives an explanation of the internal parts of the dts file, but it doesn't tell me how to practically pass it to the kernel from u-boot (e.g.: load to memory - and use bootm xxx yyy zzz) I am pretty darn confused about this whole thing. Can anybody point me to a SUCCINCT explanation of the use of a dts file (and how compile and use with u-boot to pass to kernel)?
