[RFC] ARM: BCM5301X: add NAND flash chip description
Hauke Mehrtens

Sun May 24 11:32:29 PDT 2015
This adds the NAND flash chip description for a standard chip found
connected to this SoC. This makes use of generic Broadcom NAND driver
with the iProc interface.
Signed-off-by: Hauke Mehrtens <hauke at hauke-m.de>

This would be the patch when we completely change to device tree only
for the nand flash controller.
