[U-Boot] FIT Image with same kernel but different load/entry point

[U-Boot] FIT Image with same kernel but different load/entry point

[Clément Péron]

Hi,

Is it possible to have one kernel entry in a FIT image with two
different load/entry point.

I have 2 boards which share the same kernel but doesn't have the same
entry/load point.

Thanks,
Clement

Not sure if it does exactly what you need but the pine64 board supports
multiple boards with different device trees for each board in the fit image.

No it's not why I need, I was looking to do something like this but
without doubling the size :

        kernel-bcm {
            description = "Kernel for Broadcom";
            data = /incbin/("./zImage");
            type = "kernel";
            arch = "arm";
            os = "linux";
            compression = "none";
            load = <0x61000000>;
            entry = <0x61000000>;
            hash-1 {
                algo = "sha1";
            };
        };
        kernel-imx {
            description = "Kernel for FreeScale";
            data = /incbin/("./zImage"); /* Same zImage */
            type = "kernel";
            arch = "arm";
            os = "linux";
            compression = "none";
            load = <0x12000000>; /* Different load/entry point */
            entry = <0x12000000>;
            hash-1 {
                algo = "sha1";
            };
        };

I think what you want is to use kernel_noload and then load/entry values
are ignored and we use the kernel in-place.
