if CONFIG_DEFAULT_ENVIRONMENT_PATH="" then
$(DEFAULT_ENVIRONMENT_PATH) expands to 'defaultenv "" '
The "" would cause every single file found in $(srctree) to be included in
$(ENV_FILES). This would then cause scripts/mod/sumversions.c to get
recompiled using $(CC) and fail compilation if $(CC) points to a newlib
cross compiler

Barebox does not have interrupt functionality. Nevertheless it's
sometimes useful to periodically call functions, like for example
a heartbeat LED or watchdog reset. Instead of cluttering the code
with calls to these functions this patch adds a generic polling
infrastructure. Code which might run for longer now can call
poller_call() periodically which in turn will call all registered
pollers.
This patch adds a call to poller_call in two generic pathes. First
of them is getc() which covers waiting for uart input. Second is
ctrlc() which should be called anyway from code which might run
for longer. So instead adding poller_call directly to your code,
consider checking ctrlc instead which also gives additional
convenience to the user.
The poller code is safe against reentrancy which means that it's
safe to call poller_call inside a poller.

Introduce a menu framework that allow us to create list menu to simplify
barebox and make it more user-frendly
This kind of menu is very usefull when you do not have a keyboard or a
serial console attached to your board to allow you to interract with
barebox
For the develloper part,
The framework introduce two API
1) C
that allow you to create menu, submenu, entry and complex menu action
2) Command
that allow you as the C API to create menu, submenu, entry and complex
menu action but this time the actions will be store in a function and
then be evaluated and excecuted at runtime.

some main.c cleanup:
- move the parser used when hush is disabled to parser.c
- move readline related functions to readline.c (with cmdline editing)
and readline_simple.c (no cmdline editing)
Modifications are based on the linux kernel approach and
support two use cases:
1) Add O= to the make command line
'make O=/tmp/build all'
2) Set environement variable BUILD_DIR to point to the desired location
'export BUILD_DIR=/tmp/build'
'make'
The second approach can also be used with a MAKEALL script
'export BUILD_DIR=/tmp/build'
'./MAKEALL'
Command line 'O=' setting overrides BUILD_DIR environent variable.
When none of the above methods is used the local build is performed and
the object files are placed in the source directory.
Added code for reading and writing Mac addresses to/from ID EEPROM(0x57).
With attached patch, we can use command "mac/mac read/mac save/"
to read and write EEPROM under u-boot prompt.
U-boot will calculate the checksum of EEPROM while bootup,
if it is right, then u-boot will check whether the mac address
of eTSEC0/1/2/3 is availalbe (non-zero).
If there is mac address availabe in EEPROM, u-boot will use it,
otherewise, u-boot will use the mac address defined in
MPC8641HPCN.h. This matches the requirement to set unique mac address
for each TSEC port.
