Subject: [PATCH] hw/block/m25p80: Add SFDP table for Winbond W25Q02JVM flash
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add the SFDP data table for Winbond W25Q02JVM flash device. The table
was generated under Linux kernel by dumping the SFDP content using
the following command:

```
hexdump -v -e '8/1 "0x%02x, " "\n"' \
    /sys/bus/spi/devices/spi0.0/spi-nor/sfdp
```
