ARM: do not ignore data aborts initially ...

arm_ignore_data_abort can be set to nonzero to ignore data aborts. The
default should be not to ignore data aborts. Fix this.

login: explain PASSWORD_DEFAULT option ...

This option looks like it takes the default password, but instead
it takes a filename of a file which contains the password encoded
with the selected password digest.

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: cleanup password code ...

- make some locally used functions static
- remove read_passwd which is unused
- some refactoring to make code pathes clearer

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.

ARM: pfla02: Add module revison detection ...

The pin SD4_DAT4 until SD4_DAT7 are used as revison control.
The pins will be internally pulled up so we read a 1111 for revison 1.
For revison two the first pin (bit) is pulled down (see schematic pfla-02
page 4 "SDIO, NAND-Flash".
On Module rev 1 the pins are connected to the NAND but we have only 8bit NAND
also the i.MX6 only can handle 8bit NAND flashs.

	Rev 1:  0xF

fb: Add shadowfb support ...

For speeding up rendering we need shadow framebuffers. This is currently
implemented in the gui functions. This does not work properly when two
users (splash and fbconsole) use the same framebuffer since in this case
two different shadow framebuffers will be used. This patch implements
shadowfb handling in the fb core directly. With this the fb device gets
a parameter 'shadowfb'. When this is true the fb core will allocate a
shadow fb and provide it to the users.
