[U-Boot] SquashFS and FIT images

[U-Boot] SquashFS and FIT images

[Bishop, Mark]

Is it possible to specify squashFS images in an .its file?  If so, anyone have an example or a pointer to the docs I've been searching for?

As Matthew's example shows it's totally doable. Furthermore it's not just
squashfs it could be any valid initrd. As long as your kernel is configured
to expect it u-boot will pass it along.

On that note last time i looked most if the general kernel defconfigs
didn't have squashfs enabled.

/ {
        description = "ARM64 OpenWrt FIT (Flattened Image Tree)";
        #address-cells = <1>;

        images {
                kernel at 1 {
                        description = "ARM64 OpenWrt Linux-4.4";
                        data = /incbin/("arch/arm64/boot/Image.gz");
                        type = "kernel";
                        arch = "arm64";
                        os = "linux";
                        compression = "gzip";
                        load = <0x80080000>;
                        entry = <0x80080000>;
                };


                ramdisk at 1 {
