hw_random doc updates

2008-03-25T02:22:19+00:00

Update documentation for the hw_random support to be current:

 - Documentation/hw_random.txt has been updated to reflect the
   current code:  it's a framework now, a "core" with a small
   sysfs interface, that hardware-specific drivers plug in to.
   Text specific to Intel hardware is now at the end.

 - Kconfig now references the Documentation/hw_random.txt file
   and better explains what this really does.

Both chunks of documentation now higlight the fact that the kernel entropy
pool is maintained by "rngd", and this driver has nothing directly to do with
that important task.

via-rng: enable secondary noise source on CPUs where it is present

2008-02-06T18:41:05+00:00

In the padlock spec:

"SRC Bits[9:8] Noise source select (I): These bits control the two noise
 sources on the processor that input bits to the accumulation buffers.
 On Nehemiah processors prior to stepping 8, these bits are reserved
 and undefined. The default RESET state is both bits = 0."

[HWRNG]: move status polling loop to data_present callbacks

2008-01-10T21:16:16+00:00

Handle waiting for new random within the drivers themselves, this allows to
use better suited timeouts for the individual rngs.

[POWERPC] pasemi: Broaden specific references to 1682M

2007-11-30T04:30:47+00:00

There will be more product numbers in the future than just PA6T-1682M,
but they will share much of the features. Remove some of the explicit
references and compatibility checks with 1682M, and replace most of them
with the more generic term "PWRficient".

Convert files to UTF-8 and some cleanups

2007-10-19T21:21:04+00:00

* Convert files to UTF-8.

  * Also correct some people's names
    (one example is Eißfeldt, which was found in a source file.
    Given that the author used an ß at all in a source file
    indicates that the real name has in fact a 'ß' and not an 'ss',
    which is commonly used as a substitute for 'ß' when limited to
    7bit.)

  * Correct town names (Goettingen -> Göttingen)

  * Update Eberhard Mönkeberg's address (http://lkml.org/lkml/2007/1/8/313)

intel-rng: undo mess made by an 80 column extremist

2007-07-16T16:05:46+00:00

The intel-rng printed a nice well formatted message when the port was
disabled.  Someone then came along and blindly trashed it by screwing up a
trim down to 80 columns.

Put it back into the right format and keep the overlong lines as the result
is also MUCH easier to read in this specific case.
