[PATCH 00/14] Backport BRCMNAND changes from Linux

[William Zhang]

Hi Linus,

I will try to review and test your patches late this week or early next 
week.  I don't have those old chips (v2.1, v2.2, v4) but will test on 
some of recent Broadcom broadband(BCMBCA) SoCs with v7.0 and 7.1 controller.

Thanks,
William
