From: Arnd Bergmann <arnd@arndb.de>
This is the first part of the removal of old board files, addressing
all the easy cases:
cns3xxx and iop32x get removed completely, including a handful of device
driversm while ep93xx, dove, mv78xx0, orion, footbridge and omap1 all
keep basic platform support but drop support for all boards that have
no known users.
There are seven patches for other subsystems in this series. It would
be helpful to get everything merged in the same release if there are no
objections, but I don't care if I include them in the soc tree with an
Ack from the subsystem maintainers or the patches are applied directly
into the subsystem trees.

From: Arnd Bergmann <arnd@arndb.de>
After the removal of the unused board files, I went through the
omap1 code to look for code that no longer has any callers
and remove that.
In particular, support for the omap7xx/omap8xx family is now
completely unused, so I'm only leaving omap15xx/omap16xx/omap59xx.

From: Arnd Bergmann <arnd@arndb.de>
The OMAP7xx/OMAP8xx support was removed since all of its boards
have no remaining users. Remove its spi driver as well.
