kernel: Add support for Winbond w25q128jv SPI NOR flash
Newer batches of several Mikrotik boards contain this yet-unsupported
flash chip, for instance:
- rb941-2nd (hAP lite)
- rb952ui-5ac2nd (hAP ac lite)
- RBM33G
and probably other Mikrotik boards need this patch as well.
The patch was submitted upstream by Robert Marko: https://patchwork.ozlabs.org/patch/934181/
Closes: FS#1715
