Hi Stefan,
sorry for delay, need at least two more clones of myself :)
no problem, but currently switch framework very broken :)
But let me explain how it must works.
sys/dev/switch:
switch.c - core logic
switch_if.m - newbus methods to call from core to drv
switchb_if.m - newbus methods to call from drv to core
switch_ioctl.h - driver IOCTL, exported to userland for switchctl
switch_${busglue}.c - glue to attach to different buses (mii,
obio, iicbus, spi), currently works (somehow)
mii and obio.
${family}_switch.c - switch driver
${family}_switchreg.h - switch registers definitions
${family}_switchvar.h - per driver structures
sbin/switchctl - still dumb tool for switch manipulation
most useful thing of it - get/set reg :)
Ohh, need write many manuals for it, but still busy with servers @job.
Anyway, questions/comments are welcomed!
