The cheesy uclinux mtd maps can be used for more than just the root device, so
I think we should drop the forcing.

Also, I feel like this is a policy decision that shouldnt be in the kernel in
the first place.  People who have been lazy and boot with uclinux mtd maps and
dont put root= into their commandline can simply add the appropriate root=
line either into their bootloader or into the compiled in bootargs.

Fixing at least a couple more bugs in the process.
Signed-off-by: David Woodhouse <dwmw2@infradead.org>

We attempted to insert new nodes into the tree by just using
rb_replace_node to let them replace an earlier node which they
completely overlapped. However, that could place the new node into the
wrong place in the tree, since its start could be node only before the
start of the victim, but before the node _before_ the victim in the tree
(if that previous node actually ends _after_ the new node, thus isn't
entirely overlapped and wasn't itself chosen to be the victim).
Signed-off-by: David Woodhouse <dwmw2@infradead.org>

The original code would remember, during the first pass over the tree,
a suitable place to start the insertion from when we eventually come
to add a new node.

The optimisation was broken, and we sometimes ended up inserting a new
node in the wrong place because we started the insertion from the wrong
point.

Just ditch the optimisation and start the insertion from the root of the
tree, for now. I'll try it again when I'm feeling cleverer.

This fixes a problem Artem found with the integck test tool -- we
weren't correctly keeping track of the 'overlap' flag in some cases,
which led to the nodes being played back in an incorrect order and file

The CAFÉ can handle two chip on separate chipselect lines. Hook up the
undocumented chipselect bits in the driver and probe both.

In the case of OLPC, it's not actually two separate devices -- it's a
single '1GiB' package with two 512MiB dies internally. So clear the
NAND_BBT_PERCHIP flag to treat it as a single chip for BBT purposes, and
make life easier for the firmware.

among different architectures.  It supports both host and device functions.
This driver adds its device support for Linux USB Gadget layer.
It is tested on MPC8349 and MPC8313, but should work on other platforms
with minor tweaks.  The driver passed USBCV 1.3 compliance tests.  Note
that this driver doesn't yet include OTG support.

The driver uses usb_control_msg() for exchanging data with the device.
When the driver lived freeley _outside_ the kernel tree (pre 2.6.21) the
timeouts for these calls where set to 5*HZ for reading, 1HZ for writing.
(These timeouts seemed to work fine for all users of the driver, at
least nobody complained in the last 2 years.

The current code (2.6.21-rc5) removed the 'HZ' from the timeouts and
left the driver with 5 jiffies for reading and 1 jiffy for writing. My
new machine is fast, but not that fast.

The patch also removes a useless debug statement, which was left over
from testing a broken firmware version
