This patch makes impossible the situations than path_check_prereq() can make
'return 0' without changing errno.

If we register a device we have to unregister it later when
the driver did not accept the device. Also, do not forget to
free the backingstore string.

Once we have caching in file functions we need a way to sync
the the underlying devices.

Otherwise we end up with errno not being set correctly
if a filesystem driver uses the standard open/close/read/write
functions to access its backing store.

We need to assign a new device id if we want to register
a fs with the same type of an already registered fstype.

This patch adds some basic file descriptor sanity checks to the file access
routines. Check whether the given file descriptor is in the files array range,
and whether the file entry is valid.

We can't truncate device files. Make sure that if we want to
write beyond the device that the bytes that still fit into the
device get written.

When a nor0 devices has no partitions assigned, then a call to
open() to create a file will jump with a NULL fct ptr.
Much more cheching code is missing and pointers to function are
jumped without any NULL ptr check. This must be fixed as well later.

- 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

- do more POSIX:
- use DIR instead of struct dirent
- use (struct dirent)->d_name instead of (struct dirent)->name
- switch to a new layout for U_BOOT_CMD:
- use C99 initializers to be able to add more fields to the
command struct
- add aliases for commands (needed mainly for help -> ? and test -> [
- This is not done for all commands yet, but the compiler will tell you ;)
