The reiserfs filesystem was only enabled by the ethernut5 which appears to use jffs on nand for all default usecases (Nut/OS, Yocto) and doesn't have USB Storage support enabled, but does have MMC. It's also scheduled for removal in upstream Linux.
Looking at the logs for ethernut5 it doesn't actually appear to be actively maintained either for the best part of 10+ years but I don't remove that as part of this PR but leave it to someone who may know the AT91 ecosystem better than me.
