The code was mistakenly initializing the input buffer twice.
Tested to be working on BeagleBone by adjusting CONFIG_SYS_BOOTM_LEN to 64MiB (probably works with less) and preparing uImage with:
cat arch/arm/boot/Image \ | zstd --ultra -22 --zstd=windowLog=22 \
linux.bin.zst
mkimage -A arm -T kernel uImage -C zstd -d linux.bin.zst \ -a 0x80008000 -e 0x80008000
Without the windowLog restriction, bootm fails with a zstd decompression error 7 (window too large), which I haven't troubleshooted.
There should be a bit more documentation on the feature...

Applied to u-boot/master, thanks!
