The netcat utility likes to exit when it receives an empty packet (as it
thinks this means EOF). This can easily occur when working with command
line editing as this behavior will be triggered when using backspace. Or
with tabs and command line completion. So create two netcat processes -
one to only listen (and put it into a loop), and one to do the sending.
Once the user quits the transmitting netcat, the listening one will be
killed automatically.

tools/fit_image.c:202: warning: initialization from incompatible pointer type
and changes to code to use "const" attributes in a few places where

tools: mkimage: split code into core, default and FIT image specific
This is a first step towards reorganizing the mkimage code to make it
easier to add support for additional images types. Current mkimage
code is specific to generating uImage and FIT image files, but the
same framework can be used to generate other image types like
Kirkwood boot images (kwbimage-TBD). For this, the mkimage code gets
reworked:
Here is the brief plan for the same:-
a) Split mkimage code into core and image specific support
b) Implement callback functions for image specific code
c) Move image type specific code to respective C files
Currently there are two types of file generation/list
supported (i.e uImage, FIT), the code is abstracted from
mkimage.c/.h and put in default_image.c and fit_image.c;
all code in these file is static except init function call
d) mkimage_register API is added to add new image type support
All above is addressed in this patch
e) Add kwbimage type support to this new framework (TBD)
This will be implemented in a following commit.

The value of I2C_TIMEOUT in fsl_i2c.c has several problems. First, it is

no sense to derive it from a clock rate. Second, the current value (250) is

necessary for multiple-master arbitration is larger than the timeout for basic
