There is no existing MIPS port of iPXE.  I am assuming that you may have 
modified the build process to support MIPS.  In doing so, you would have 
needed to provide implementations for several per-CPU-architecture 
functions.

My guess is that you have probably chosen to link in an external C 
library in order to achieve this, and that the bulk of your code size is 
coming from this external library.

Without seeing your modified code, we cannot sensibly help you.  You 
will need to publish the code in accordance with the GPL at some point 
anyway, so you may as well publish it now.

Thanks,
