riscv64 - SiFive Unmatched regression?

Running into a potential regression on the SiFive Unmatched.

These images function as expected:  (u-boot Nov 2021, OpenSPI 0.9)

UART output, no issues.

The latest master u-boot images no longer boot from the SD card in any testable configuration:

  * master as of today + OpenSPI 0.9
  * master as of today + OpenSPI 1.0

The symptom of "no longer boot" is the Unmatched showing a bit of gibberish on the UART.

All SD cards provisioned using identical known-good steps documented by u-boot.
