The first problem (which I actually noticed while trying to fix the second problem with transfers >64KiB) seems to be a generic issue which affects several drivers so I fixed it in the core. The series has been tested on ARTPEC-8, which has a version of the IP similar to Exynos 7 and with 64 byte FIFOs (compatible with "tesla,fsd-spi").
