Check https://git.lede-project.org/?p=source.git&a=search&h=HEAD&st=commit&s=yaffs
for a few pointers. While I have no experience with the devices in 
question, the gist seems to be that those devices have been converted 
to UBI instead of the non-mainline yaffs2 (by using a container format
that looks similar enough to yaffs2 to be accepted by the bootloader
while actually being UBI based), this apparently allowed to drop support
for yaffs2 without sacrificing support for these devices.
