I was looking at the 82559 driver as an example.

The platform is custom (based on a mips tx49 derivative).  There
seems to be some inconsistiency in how this gets done.  A quick
grep-find in devs/eth shows:

find /ecos-z/ecos/packages/devs/eth -type f -print0 | xargs -0 -e grep
-n cyg_pci_configure_device 
/ecos-z/ecos/packages/devs/eth/amd/pcnet/current/src/if_pcnet.c:349:
if (cyg_pci_configure_device(&dev_info)) {
/ecos-z/ecos/packages/devs/eth/intel/i21143/current/src/if_i21143.c:2056
:            if (cyg_pci_configure_device(&dev_info)) {
/ecos-z/ecos/packages/devs/eth/intel/i82544/current/src/if_i82544.c:2641
:            if (cyg_pci_configure_device(&dev_info)) {
/ecos-z/ecos/packages/devs/eth/intel/i82559/current/src/if_i82559.c:2918
:            if (cyg_pci_configure_device(&dev_info)) {
/ecos-z/ecos/packages/devs/eth/mips/atlas/current/src/if_atlas.c:475:
if (!cyg_pci_configure_device(&dev_info)) {
/ecos-z/ecos/packages/devs/eth/via/rhine/current/src/if_rhine.c:369:
if (cyg_pci_configure_device(&dev_info)) {

Grepping in packages/hal/mips shows no matches, and doing a
wider grep shows some arm derivatives seem to have calls to
it in the hal functions.

So it's done sometimes in the chip drivers, sometimes in the 
platform "glue" function, and sometimes in the hal.
