I am a bit confused with mkimage. I am trying to build and boot an uncompressed image for a ppc8323. I can run mkimage with a "-C none" option and get a 3.6Mbyte kernel (compressed it is about 1.6MBytes), but when I boot it with bootm, I hang after loading the device tree near 0x03ffxxxx.
It certainly may be possible that the larger, uncompressed kernel is stepping on the ram location of the device tree, but I dont yet know now to manipulate the address where the fdt is loaded. I try to use mkimage with a .its file, but mkimage doesnt seem to accept the "-f device.its" argument where I define the kernel and the device tree .dtb file.
I would appreciate a few pointers on how one might get an uncompressed image booting in u-boot and if possible, I would like to understand and use the "-x" for xip option.
