OK, I fixed up the sizes myself, here are the write tests attached.
Before each run I create data.bin with:
dd if=/dev/urandom count=$((16 * 1024 * 1024)) iflag=count_bytes of=data.bin
Note that I have a S25FL129P......0, not S25FL128P......0, for me
spi_block_erase_20 does not work at 64kB, but spi_block_erase_d8 does.
This is because on S25FL129P......0 spi_block_erase_20 is used for the 4kB
access.
If you send an updated version of the patch I can do more tests.
Thanks,
Antonio

Q: Why is top-posting such a bad thing?
