[PATCH 5/5] Remove REDWOOD_5 and REDWOOD_6 config options and conditional code

[PATCH 5/5] Remove REDWOOD_5 and REDWOOD_6 config options and conditional code

[Christian Dietrich]

The config options for REDWOOD_[56] were commented out in the powerpc
Kconfig. The ifdefs referencing this options therefore are dead and all
references to this can be removed (Also dependencies in other KConfig
files).

REDWOOD_4 does not appear to be in the tree either so this mapping driver
should be deleted if the patch is otherwise acceptable.  Besides we
would express the info contained in this simple map driver the device tree
using physmap_of.

[PATCH 0/2] Removing dead code

[Christian Dietrich]

Hi all!

I merged the two patches from Christoph Egger[1] to remove the
REDWOOD_[456] config depends. And wrote a second patch, which removes
the redwood/mtd mapping module. I hope this is now acceptable to bring
it into the kernel, if this options are really dead.       

Regards

        Christian Dietrich

This seems fine with me.

The only question is which tree it coms through.  I'm happy to take it
in via mine if the netdev and MTD people are fine with that.  Otherwise,
my ack is below.
