after rebasing my internal branch to v2023.8.0, my system doesn't
boot anymore:

Since commit
2ab6780b80e3 ("FIT: add first support for compressed images")
Barebox uses the "compression" key from the FIT image which breaks loading my
ramdisk (LZ4 compressed, should be decompressed by the kernel). Although the
compression parameter should be "none" in that case, it actually isn't. Older
Yocto releases used to set the actual compression type here:
https://git.yoctoproject.org/poky/commit/?h=kirkstone&id=2c58079222310443f08df51e9fd6ce234e7e0019
In U-Boot, the "compression" parameter is ignored for ramdisks due to this
problem. Only a warning is printed:

https://source.denx.de/u-boot/u-boot/-/blob/master/boot/image-fit.c#L2289
Could you also apply this workaround to Barebox?

Christian
