Probing for Winbond W25Q80.V, 1024 kB: probe_spi_rdid_generic: id1 0xef, id2 0x4014
Found Winbond flash chip "W25Q80.V" (1024 kB, SPI) at physical address 0xfff00000.
Chip status register is 0x00.
This chip may contain one-time programmable memory. flashrom cannot read
and may never be able to write it, hence it may not be able to completely
clone the contents of this chip (see man page for details).
