Alexander Clouter b388233084 ARM: orion5x: use safer FPGA ID 'default' for TS-78xx
Originally the FPGA ID checking switch statement left disabled all the
TS implemented FPGA devices if the ID was unknown to it.  Michael Spang
created a fix in f9b1184e that changed the default to enable the devices
in the event TS silently release more revisions into the wild, this
unfortunately breaks custom FPGA bitstreams.

This patch amends the switch statement so that the TS devices are only
enabled if on the revision number is unknown (whilst the magic matches).

Changelog:
 v2: neater implementation and some cosmetic changes
 v1: initial release <20110305112937.GA22117@chipmunk>

Alexander Clouter 17718e17a2 [ARM] update FPGA revisions for TS-7800
New FPGA revisions have been released and seen in the wild on the
platform, so it's time to update the list.

Alexander Clouter 0c1355e36f [ARM] orion5x: update of FPGA ID's for the TS-78xx
Received official word finally from Technological Systems on which
FPGA ID's they have released unto the world.  Also an additional of
a dummy entry matching the FPGA ID of the Verilog template on our
wiki.

Alexander Clouter 195f4a170e [ARM] orion5x: added a new FPGA ID set for the TS-78xx
Stefan Agner found his board comes with 0x00b480/0x02 but the main
board also has Rev B printed on it like my 0x00b480/0x03.  Some light
enum renaming was needed but it was to be expected.

Alexander Clouter 39008f959f [ARM] orion5x: TS-78xx support for 'hotplug' of FPGA devices
the FPGA on the TS-7800 provides access to a number of devices
and so we have to be careful when reprogramming it.  As we
are effectively turning a bus off/on we have to inform the
kernel that it should stop using anything provided by the
FPGA (currently only the RTC however the NAND, LCD, etc is
to come) before it's reprogrammed.

Once reprogramed, we can tell the kernel to (re)enable things
by checking the FPGA ID against a lookup table for what a
particular FPGA bitstream can provide.
