>  - Extend brcmstb GISB bus driver to work on BE systems (currently LE-only).

For the entire series:

Acked-by: Florian Fainelli <f.fainelli at gmail.com>

I will probably take the brcmstb_gisb.c changes separately and submit
them to arm-soc as a "drivers" pull request since this driver has
typically been routed that way.

Thanks!
