Please add an entry to the MAINTAINERS file.
Also, please run your patch through checkpatch - it complains about a
number of style errors:

Is this really correct? 303 ??

These magic numbers should probbly be moved to some header file ?

Incorrect multiline comment style.

More hard-wired magic values?

No timeout?

Braces needed for multiline statement.

Do you plan to use this? Otherwise please just omit such dead code.

Ditto...

This should be a printf(). Any such automatic changes are always
worth to be told explicitly.

Did you ever try building without CONFIG_DRIVER_TI_CPSW set? I bet
this causes a few compiler warnings. [Hint: You define a label, but
don't use it anywhere.]

Does this really make sense? I doubt you will ever need more than 10%
of this size - so you are just wasting a lot of time for checksumming
unused memory...

Please do not define values for logical variables like this one;
please fix globally.
> +#define CONFIG_ENV_IS_NOWHERE
Really?
Thanks!
