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 Signed-off-by: Baptiste Jonglez <git@bitsofnetworks.org> Cc: Robert Marko <robimarko@gmail.com> [Rebased + refreshed on current kernels] Signed-off-by: Koen Vandeputte <koen.vandeputte@ncentric.com>
