I tested this patch, and it works well.
But there are some notes

1) m25p80 driver DT support seems strange ??

   ${LINUX}/Documentation/devicetree/bindings/mtd/m25p80.txt
   has explain about DT of m25p80 driver, but,
   ${LINUX}/drivers/mtd/devices/m25p80.c
   doesn't have driver :: of_match_table.
   but, it is using of_property_read_bool() on probe.
   Is it out-of-tree support ?? I'm not sure,
   anyway, m25p80 driver didn't probe.
   So, I quick-hacked this issue in my local environment.

2) it needs Geert's this patch

   Subject: [PATCH] mtd: m25p80: add support for the Spansion s25fl008k chip
   Date:	Tue, 11 Feb 2014 09:51:18 +0100

   Kernel will hung-up without this patch

For HSPI / BockW point of view
