d2b1bd1422 mtd: bcm47xxsflash: convert kzalloc to avoid invalid access 
mtd is just member of bcm47xxsflash, so we should free bcm47xxsflash not
its member. So I use devm_kazlloc instead of kazlloc to avoid it.

* Changelog:
   convert to devm_kzalloc

265dfbd9ae mtd: bcm47xxsflash: implement ChipCommon R/W ops 
They are needed for erasing/writing. Use a magic pointers and small
functions to prepare code for adding other buses support in the future
(like SSB).

To implement erase and write support we need to "talk" with ChipCommon
BCMA core which serial flash it attached to.

2d13dc3bce mtd: bcm47xxsflash: register this as normal driver 
When platform_driver_probe() is used and no device is registered for
this driver -ENODEV is returned and and error message is shown. Not all
BCM47xx SoC have a serial flash chip controller and chip and for them
an error message was shown.

5fe42d5bf2 mtd: basic (read only) driver for BCMA serial flash 
This registers MTD driver for serial flash platform device. Right now it
supports reading only, writing still has to be implemented.
