Well, if your Linux kernel image and Device Tree are stored in a
squashfs filesystem, then U-Boot proper needs SquashFS support, right ?
And that is completely independent of whether the SPL has SquashFS
support to be able to load U-Boot proper (which potentially could be
stored on SquashFS as well).
It's very much like the FAT filesystem case: if you have U-Boot proper
and your Linux kernel image in a FAT filesystem, then the SPL needs FAT
filesystem support to load U-Boot proper, and U-Boot proper needs FAT
filesystem support to load the Linux kernel image.
Am I missing something here ?
Best regards,
Thomas
