Do these as two separate steps and run "fdt > print" in between to see what changes occur. I don't have any board specific fixups. We have the chosen already in the dts before I compile it to a blob. We do this because with the FPGA many people don't use a boot loader. > > > => bootm 0x1c00000 0x1800000 0x1000000 > > ## Booting image at 01c00000 ... > > Image Name: Linux-2.6.26-rc8 > > Image Type: PowerPC Linux Kernel Image (gzip compressed) > > Data Size: 1536962 Bytes = 1.5 MB > > Load Address: 00000000 > > Entry Point: 00000000 > > Verifying Checksum ...

I found these properties in the code, but it doesn't seem right to need it, I must be still missing something.
