[U-Boot] SSBI driver

[hanumant]

Hi

   I am trying to implement a SSBI driver for a board. . The driver is 
meant to be portable to multiple boards by the same vendor.
Keeping this in mind

1)Would drivers/misc/ be the right location to implement this driver?
2)If not can I make a ($vendor)-common in the cpu directory to implement 
the driver given that the driver is going to be applicable for multiple 
socs by the same vendor. ie have something like the below.
have arch/arm/cpu/armv7/($vendor)-common & arch/arm/cpu/armv7/($SOC).
I believe there is already precedent for this?

Any input is appreciated.

Thanks
