Currently all devices have an id meaning that all devicenames
end with a number. This patch adds a DEVICE_ID_SINGLE to make
it ppossible to register a device without an id assigned to
it.

Support for the old DM9000E device is now part of the new dm9k.c driver. So,
remove the old driver source and switch all users to the new driver.

For disk like devices attached to MCI, ATA or USB it depends on the order they
will be recognized. So an unique number for all disk like devices is required.

Add a helper function for boards to register their memory
devices. This makes the board code smaller and also helps
getting rid of map_base and struct memory_platform_data.
And switch all of the memory to it

We might want to add real resource tracking later. Also
The first resource may not be a IORESOURCE_MEM at all.
For these reasons introduce a wrapper function for
driver so that they do not have to fiddle with resources
directly.

for now we keep the old map_base and size temporary but will switch all of
the used step by step to them resource way
and mirror the first resource to the map_base and size if available

This makes it possible to compile without devfs. devfs_create/devfs_remove
is used by drivers and thus must still be present even without devfs support.
Also, this patch adds cdev_open/cdev_close/cdev_flush/cdev_ioctl calls to
work with devices without using the file api.

dev_name is supposed to return the name of the device plus the id
currently we use %s%d format where in the kernel the use %s.%d
we may think to switch to this format for the device name and keeping the %s%d
for the devfs
this will be usefull to not modify the clock device name as example

Change device parameters so that the memory management is in generic
code. This also removes the need of storing statically initialized
parameters as they are stored in a struct list_head for each device.

We accidently have two list implementations in the tree:
include/list.h and include/linux/list.h. This patch moves
the latter (newer one) to include/linux/list.h.

Some devices, especially the ones doing DMA should be disabled before
giving control to an OS. We take the simple approach here: Just shutdown
the devices in the reverse order they were activated.

Add an own device id for partitions. This is necessary to allow
the partition layer to check if the given device is really a partition.
Also, check for readonly flag in erase.

- Use device tree structure to implement partitions
- Let devinfo print a nice tree
- Introduce 'fixed' partitions which are not removable
- Fix mount: It was not possible to mount on a relative path.
With this function we can get a pointer to directly memory mapped
devices like nor flash or RAM. Useful for bootm where we save one
memcopy when the image is mappable
