You're matching too much here (see IO's complaints below).
Only do
  mmc1 = wrap(hw.mmc1);
  mmc2 = wrap(hw.mmc2);
  mmc3 = wrap(hw.mmc3);
  i2c0 = wrap(hw.i2c0);
  i2c1 = wrap(hw.i2c1);
(or only match for that pattern that matches once).

Ok, now that's strange, that should not happen. In L4Linux, do you have
CONFIG_L4_SERVER enabled or disabled? Does arch/l4/kernel/main.o contain
the l4x_srv_init symbol or not
(check with 'nm arch/l4/kernel/main.o | grep l4x_srv_init')?
