mfd: add stmpe-i2c driver ...

The stmpe mfds can be connected via i2c and spi. This driver provides the basic
infrastructure for the i2c kind. It can be added as a normal i2c-device in the
board code. To enable functions a platform_data struct has to be provided, that
describes what parts of the chip are to be used.

envfs: add support of variable inode size ...

Introduce a struct envfs_inode_end with more data.
Today this will just containt the file mode to be able to add the symlink
support.

But this is compatible with the previous envfs version as they will do not
care about the extra as the previous version is just reading the filename and
then consume the extra data without using them.

Increase the envfs version to 1.0

mtd nand: implement buswidth detection ...

This introduces a new NAND_BUSWIDTH_AUTO flag which can be used
to automatically detect the nand buswidth. The id is always read
in 8bit mode. An additional callback is needed to switch the nand
controller into 16bit mode.
This currently depends on a safe read_byte (always) and read_buf
(for onfi-only flashes) callback. It has been tested on OMAP, but
is not something that generally works. For this reason the existence
of the set_buswidth callback is used to determine whether we are
able to do autodetection or not.

Add compressed image support ...

This allows for creating a lzo compressed binary unsing the pbl.

Only copy the piggydata if needed.

Add CONFIG_PBL_FORCE_PIGGYDATA_COPY option
In some case we need to copy the PIGGYDATA as the link address
as example we run from SRAM and shutdown the SDRAM/DDR for
reconfiguration but most of the time we just need to copy the
executable code.

Add pre-bootloader (pbl) image support ...

This allows for creating a pre-bootloader binary for
 - nand boot
 - mmc boot
 - compressed image

The pbl will be incharge of the lowlevel init if needed.
The barebox will skip it.

Import string functions from linux 3.4 (arch/arm/boot/compressed/string.c) and
implement a dummy panic.

For now on introduce dummy zbarebox* targets and c code that will contain later
the decompressor. This only implemeted on ARM.
