Mount without argument always print a "none" as device name mounted
because entry->parent_device is always NULL.
The problem is the mount function in fs/fs.c. parent_device is
initialized to NULL and never updated. With this patch,
parent_device is set with the mounted device name.
Moreover, the mount function has been modified to print the device
name plus device id using the dev_name function.

Some ops do not handle read with count = 0 correctly. They do
not have to if this is catched in the upper layer.

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

path_check_prereq is supposed to return 0 when a file does
not exist and S_UB_DOES_NOT_EXIST is given. stat() changes
errno, so we have to set errno back to 0 before returning.

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.

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.
int open(const char *pathname, int flags);
-> int open(const char *pathname, int flags, ...);
int mkdir(const char *pathname);
-> int mkdir(const char *pathname, mode_t mode);
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 ;)
