hush: do not convert to return code too early ...

parse_stream_outer used to convert a exit value to a return code,
but parse_stream_outer maybe inside a recursion. This means that
the exit status is lost in this case. Test case:

if [ 0 = 0 ]; then
	false
	exit $?
fi

echo "shouldn't be here"

Without this patch "shouldn't be here" will be printed.

This is because the USBHOST module is not enabled. The module enable
is is normally done in mach-omap/xload.c which never gets called.

Since we're configuring the USBHOST CLKCTRL register in the board file
anyway, we might as well explicitly enable the module in the same place.

ARM pcm038: Switch to new environment ...

This switches the pcm038 board to the new environment template and

UBI support as the pcm038 image is getting bigger and bigger and UBI
seems to be the most unused big (in size) feature.

Add next generation default environment template ...

This adds a new environment template which aims to be more flexible
and configurable. Instead of having mainly two scripts (a config script
and a boot script) this template uses initscripts which control the
startup behaviour and configuration. Also we have boot scripts in
/env/boot which configure a single boot configuration. Additional
boot entries can be added by board specific entries or during runtime
by copying and editing a template entry.

Some more helpers handle for example network interfaces which can now
be brought up with 'ifup'. We use the automount feature to configure
mountpoints together with the commands to bring up the devices behind
these mountpoints.

Optionally menu support is available which hides many details behind
a nice looking interface.

bootm: Add default images variables ...

It turns out useful to be able to configure bootm before its usage.
This allows us to overwrite bootm settings on an individual base.
This patch adds global variables to configure the kernel image, the
initrd image and the devicetree image. These values will be used
unless overwritten explicitely with command line switches.

lseek: return -1 instead of -errno ...

The patch making errno a positive value has another bug:
lseek was switched to return -errno instead of -1. This does not
work since we can lseek we can address the whole 4G address space,
have of which has a negative offset when interpreted as a signed
integer. Let lseek return -1 on failure again instead.
