execute_binfmt may return negative return values which hush interprets
as 'exit'. Catch this and print an error message instead.
Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
'exit' used to do its job by returning value < 0. This is a sign
for hush that 'exit' is executed. This has problems:
- Often commands accidently return a negative value. This causes
the shell to exit.
- execute_binfmt returns a negative value when it does not find
a binary to execute. This again causes the shell to exit.
Returning a negative error value seems to be the right thing
to do, but catching this in the shell would mean that the exit
command does not work anymore.
- if called without arguments exit is supposed to return the code
of the last command. As a command exit has no access to this code.
This patch changes exit to be a builtin and also fixes the last return
code problem. While at it, update the help text.

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.

Use the prefetch engine to improve NAND performance. The howto
is derived from the Kernel. Unlike the kernel we do not make
the access mode configurable.

Instead of passing several options into the nand register function
it is much more straight forward to just pass the platformdata.
While at it, rename the function to omap_add_gpmc_nand_device to
better describe what it does.

This allows for creating a pre-bootloader binary for
- nand boot
- mmc boot
- compressed image
Currently on the compressed image is implemented the boot really on current lowlevel
init support. In a second step this could be move to the pbl c code with generic framework.
The pbl will be incharge of the lowlevel init if needed.
The barebox will skip it.
The decompressor support lzo and gzip and allow to add easly more.

This patch prevents to stop the autoboot randomly for the CALAO MB-QIL-A9260.

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.

- dev_ready is supposed to return whether the device is ready or
not, not to poll until the device is ready.
- dev_ready should return true for ready and false for not ready
- waitpin polarity is not needed (at least the kernel does not have it)
- wait_mon_mask must be 32bit.
The code was unused since no board specified a wait pin, so no breakage
included. This also removes the now unused timeout variable from
platformdata.
