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.

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
	Rev 2:  0xE

fb: fbconsole: Add missing blits ...

When using offscreen rendering we need some more points where we
blit the offscreen buffer to the screen. Add them.

gui: implement blitting screen areas ...

So far we only supported blitting the whole screen from the shadow
fb to the framebuffer. Add a function to blit areas.

gui: Use fb provided shadowfb for offscreen rendering ...

The fb core now has builtin support for offscreen rendering, use
this and drop offscreen handling in the gui code.

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.

splash command: depend on CONFIG_VIDEO ...

The splash command only makes sense with framebuffer support enabled, so
add the corresponding dependency to Kconfig.

Since we no longer have custom gpio function prototypes we can
drop the prototypes from asm-generic/gpio.h can add them to
include/gpio.h instead. While at it add static inline dummy wrappers
for !CONFIG_GENERIC_GPIO so that code using gpios can compile without
gpio support.
