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.

This switches the pcm038 board to the new environment template and
does the necessary defaultconfig adjustments. Additionally it disables
UBI support as the pcm038 image is getting bigger and bigger and UBI
seems to be the most unused big (in size) feature.

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.

It turns out useful to be able to configure bootm before its usage.
This allows us to overwrite bootm settings on an individual base.

initrd image and the devicetree image. These values will be used
unless overwritten explicitely with command line switches.

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.

This is limited board support for the Freescale P2020RDB in single CPU
mode. The DDR is configured for a memory bus running at 667Mhz.
The system boots from NOR flash and provides the console at 115200
bauds, no other drivers are included.
Finally, the PPC Kconfig and make file make the building of
