06bffc6ea5 rm9200 lowevel_init: don't touch reserved/readonly registers
For some reason the AT91rm9200 lowlevel init writes to a bunch of
reserved or read-only addresses.  All the boards seem to define the
value-to-be-written values as zero ... but they shouldn't actually
be writing *anything* there.

No documented erratum justifies these accesses.  It looks like maybe
some pre-release BDI-2000 setup code has been carried along by cargo
cult programming since at least late 2004 (per GIT history).

Here's a patch disabling what seems to be bogosity.  Tested on a
csb337; there were no behavioral changes.

52cb4d4fb3 stdio/device: rework function naming convention
So far the console API uses the following naming convention:

	======Extract======
	typedef struct device_t;

	int	device_register (device_t * dev);
	int	devices_init (void);
	int	device_deregister(char *devname);
	struct list_head* device_get_list(void);
	device_t* device_get_by_name(char* name);
	device_t* device_clone(device_t *dev);
	=======

which is too generic and confusing.

Instead of using device_XX and device_t we change this
into stdio_XX and stdio_dev

This will also allow to add later a generic device mechanism in order
to have support for multiple devices and driver instances.

74de7aefd7 Add "source" command; prepare removal of "autoscr" command
According to the doc/feature-removal-schedule.txt, the "autoscr"
command will be replaced by the "source" command in approximately 6
months from now.

This patch prepares this change and starts a 6 month transition
period as follows:

- The new "source" command has been added, which implements exactly
  the same functionlaity as the old "autoscr" command before
- The old "autoscr" command name is kept as an alias for compatibility
- Command sequences, script files atc. have been adapted to use the
  new "source" command
- Related environment variables ("autoscript", "autoscript_uname")
  have *not* been adapted yet; these will be renamed resp. removed in
  a separate patch when the support for the "autoscr" command get's
  finally dropped.

c7d703f3f3 usb.h: use standard __LITTLE_ENDIAN from Linux headers
Rather than forcing people to define a custom "LITTLEENDIAN", just use the
__LITTLE_ENDIAN one from the Linux byteorder headers that every arch is
already setting up.

480ed1dea1 use correct at91rm9200 register name
This fixes a naming bug for at91rm9200 lowlevel init code:
NOR boot flash is on chipselect 0, not chipselect 2.  This
makes code use the register name from chip datasheets.
