[U-Boot] [PATCH 12/20] arm/km: add support for external switchconfiguration

Dear Holger,

I see two situations:

1) We are talking about code to load a bitstream into the FPGA, i. e.
   to "program it".  Such code should always be generic enough to put
   it under drivers/fpga/ (if the existing code there does not already
   cover the task).

2) We are talking about driver code for some preipheral implemented
   in the FPGA.  In many cases we find these peripherals to be pretty
   generic (say, UARTs, GPIOs, network interfaces, etc.).  In such
   cases there is no doubt that driver code should go to drivers/ .
   ONly in case you have areally, really special feature implemented
   that you need supported in U-Boot.  OK, then such drivers are
   probably better kept in your board directory.

Note that there will always be cases where hindsight will show that
the initial location was not perfect.  That is perfectly normal ;-)

Best regards,

Wolfgang Denk
