boot command: Allow to enable watchdog ...

Enabling the watchdog before booting the kernel is a common usecase.
Add an option to the boot command and also add a global variable for
it to make it configurable easily.

crypto: fix selecting of digests ...

SHA1 is meant as a boolean option which is true when sha1 support is available.
This works because the providers (DIGEST_SHA1_GENERIC and DIGEST_SHA1_ARM) have
a 'select SHA1'. However, consumers like the sha1sum command do a 'select SHA1'
to enable SHA1 support. This of course does not work; selecting SHA1 will not
select any of the SHA1 providers.

This is broken for all digest consumers. We have to explicitly select a digest
provider, that is DIGEST_*_GENERIC to enable the corresponding digest.

This means now we will always have the generic digest in the binary, even
when an optimized one is enabled. There is no sane way in Kconfig to
"select provider for feature xy", so let's live with the overhead in the binary.

login: rework login mechanism ...

We used to have the login functionality in the /env/bin/init script.
This is hard to review and it's too easy to break the login functionality
with changes to this script. Move the places to ask for a password to
C code where we have only a few places where we have to ask for a password.
Mainly these are run_shell() and the menutree command.

This patch introduces a login() function which will only return if the correct
password has been entered. Following calls will return immediately without
asking for a password again.

restart: replace reset_cpu with registered restart handlers ...

This replaces the reset_cpu() function which every SoC or board must
provide with registered handlers. This makes it possible to have multiple
reset functions for boards which have multiple ways to reset the machine.
Also boards which have no way at all to reset the machine no longer
have to provide a dummy reset_cpu() function.

The problem this solves is that some machines have external PMICs or
similar to reset the system which have to be preferred over the
internal SoC reset, because the PMIC can reset not only the SoC but also
the external devices.

To pick the right way to reset a machine each handler has a priority. The
default priority is 100 and all currently existing restart handlers are
registered with this priority. of_get_restart_priority() allows to retrieve
the priority from the device tree which makes it possible for boards to
give certain restart handlers a higher priority in order to use this one
instead of the default one.

commands: Add dhrystone ...

This tool will help to measure the system performance.

Some SoCs haven't the possibility to route their clocks to the output pins.
So you can use dhrystone to get a feedback about the clock speed.

graphics_utils: Let fb_open allocate the screen ...

Allocate the screen dynamically in fb_open. This opens the way to create
a fb_create_screen function which takes a struct fb_info * instead of a
filename. This is suitable for the framebuffer console which already has
a struct fb_info *.

commands: add spd_decode command ...

spd_decode command is used for decoding and printing
in human-readable format the information found
in memory module SPD EEPROMs.

There is the decode-dimms program from i2c-tools linux
package (see http://www.lm-sensors.org/wiki/I2CTools)
just for the same purpose.

Though spd_decode source code is based on decode-dimms
perl code there is a difference.
