Hi Jonas ,
Enabled zstd support , facing build issues related to zstd . Had you
faced this build error , pasted below :

aarch64-linux-gnu-ld.bfd: lib/zstd/decompress/zstd_decompress.o: in
function `ZSTD_DDictHashSet_getIndex':

make[1]: *** [scripts/Makefile.spl:527: spl/u-boot-spl] Error 1
make: *** [Makefile:2059: spl/u-boot-spl] Error 2

I'm missing anything to enable in configs ? any suggestions to these build error

Thanks and Regards ,
