Add pread and pwrite functions.
Split read and write functions to save some space.
The functions pread and pwrite saves and sets the file
position to a given offset and restore them afterwards.
This also makes the nandtest command use these function
which is necessary to not break compilation for the nandtest
command.

Having the board config file in /env/init has the problem that
the settings in /env/config are overwritten in the init sequence.
This moves the config-board files to /env/ and sources them explicitly
from /env/bin/init before sourcing /env/config

device_platform_driver() - Helper macro for drivers that don't do

Change getopt optstring parameter type to const char *.
Also change type to const char * of tmp variable which
pointed to optstring. This will only handle readonly.

HAVE_CONFIGURABLE_MEMORY_LAYOUT was first meant as a feature, now it's a
feature to remove it. barebox on ARM now completely uses the memory passed
in from the lowlevel code and configures the malloc area and stack space
during runtime making it obsolete to hardcode these values.
Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
Defining STACK_BASE and MALLOC_BASE only makes sense when
either CONFIG_MEMORY_LAYOUT_DEFAULT or CONFIG_MEMORY_LAYOUT_FIXED
is set, so use separate #ifdefs instead ot #if/#else

This optionally enabled the MMU in the PBL or during early startup for
the non PBL case. The regular MMU init code will pickup the already enabled
MMU later. This might complicate debugging early code, so this has been
made optional.
Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
Move early mmu code to a separate file so that it can be
used from the pbl and the regular image. Disabling the mmu
can be dropped since the regular mmu code is now able to
pickup an enabled mmu.
