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.

fat_stat in fs/fat.c declares finfo but doesn't initialize it.
When get_fileinfo is called, fno->lfname and fno->lfsize are
tested but haven't been zeroed...This can lead to a wrong
behavior.

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.

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

This makes it possible to compile without devfs. devfs_create/devfs_remove

Also, this patch adds cdev_open/cdev_close/cdev_flush/cdev_ioctl calls to
work with devices without using the file api.

When a nor0 devices has no partitions assigned, then a call to

Much more cheching code is missing and pointers to function are

With this function we can get a pointer to directly memory mapped

- 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 ;)
Modifications are based on the linux kernel approach and
support two use cases:
1) Add O= to the make command line
'make O=/tmp/build all'
2) Set environement variable BUILD_DIR to point to the desired location
'export BUILD_DIR=/tmp/build'
'make'
The second approach can also be used with a MAKEALL script
'export BUILD_DIR=/tmp/build'
'./MAKEALL'
Command line 'O=' setting overrides BUILD_DIR environent variable.
When none of the above methods is used the local build is performed and
the object files are placed in the source directory.

Old, obsolete and duplicated code was cleaned up and replace by the

* define a single, static partition
* use mtdparts command line option and dynamic partitioning
Default is static partitioning.
