Log: Tag all EWSR chips correctly.
All SPI chips without a WRSR feature bit set were evaluated except the Sanyo LF25FW203A for which no datasheet is available.
The following list includes all SPI-capable chips that still have no WRSR feature bit set: - AT26DF041 - AT45CS1282 - AT45DB011D - AT45DB021D - AT45DB041D - AT45DB081D - AT45DB161D - AT45DB321C - AT45DB321D - AT45DB642D
All of them have no write function set and can be therefore ignored for now.
Apart from those the generic chips are also not tagged. The opaque flash interface should not be affected. The SFDP dummy chip is changed to explicitly set EWSR if it can't deduce it dynamically. The vendor detecting generic chips can't write anyway.
