Commit c3c016cf75360c2a0d0a065b64b438aaf7720576 is a part of the problem:
offset 0x40000 is protected and cannot be erased
=> sf help
No SPI flash selected. Please run `sf probe'
=> sf probe
...
SF: Detected N25Q512 with page size 256 Bytes, erase size 4 KiB, total
64 MiB
cadence_spi_set_speed: speed=1000000
=> sf protect unlock 0x40000 0x20000
cadence_spi_xfer: len=1 [bytes]
cadence_spi_xfer: len=1 [bytes]
=> saveenv
Saving Environment to SPI Flash...
Best regards,
