Sascha Hauer 77322aa896 Treewide: remove address of the Free Software Foundation
The FSF address has changed in the past. Instead of updating it
each time the address changes, just drop it completely treewide.

Sascha Hauer 8d064097eb fs: fix standard zero, full devices
The standard devices are currently broken since they have
the size ~0. As now files use loff_t as file size which is a signed
type the read implementation gets confused and now returns -1.

The current implementation also has the (somewhat theorical) problem
that we do not have real streaming devices, so /dev/zero went out
of zeroes after reading 4GB (or now LLONG_MAX).

This patch introduces a new cdev flag DEVFS_IS_CHARACTER_DEV and a new
file size flag FILE_SIZE_STREAM which makes it possible to create
real stream devices instead.

Sascha Hauer 5f03074ea9 resource: store 'end' instead of 'size' in struct resource
Storing the size instead of the resource end in struct resource was
a mistake. 'size' ranges from 0 to UINT[32|64]_MAX + 1 which obviously
leads to problems. 'end' on the other hand will never exceed
UINT[32|64]_MAX. Also this way we can express a iomem region covering
the whole address space.

Sascha Hauer 30be97aff2 devfs: factor out core devfs functionality
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.

  - 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 ;)
