-Subject: [PATCH] mtd: spi-nor: fix spansion quad enable
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-With the S25FL127S nor flash part, each writing to the configuration
-register takes hundreds of ms. During that  time, no more accesses to
-the flash should be done (even reads).
-
-This commit adds a wait loop after the register writing until the flash
-finishes its work.
-
-This issue could make rootfs mounting fail when the latter was done too
-much closely to this quad enable bit setting step. And in this case, a
-driver as UBIFS may try to recover the filesystem and may broke it
-completely.
