Hi Daniel,
it seems to me that your commit 2809d0000744 ("kernel: support FIT
partition parser on mtdblock devices") is causing a regression in
mounting squashfs rootfs when CONFIG_FIT_PARTITION is enabled.
The following workaround fixes it, but maybe you can make a better fix,
since you're more familiar with the code.
