Side note: not sure this was touched on, and not sure what the
implications are, but let me just mention that some SPLs need this
ability too (this causes SPL to grow, which is probably the reason that
some ARM boards failed to build once the i2c linker lists were added to
the SPL lds file and until some other feature was removed).

Amicalement,
