From aa0aa47aa176133ff302c4a5cea785d971bc26b3 Mon Sep 17 00:00:00 2001 From: Baptiste Jonglez Date: Thu, 18 Oct 2018 11:08:20 +0200 Subject: 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.
