Short version:
I want to start converting m68k (including nommu) to use DT for booting
so I can add few cool boards I have (e.g. dual 040/060 VME board..).
I need ideas, help etc. Maybe if someone converted an m68k machine they
are using to DT alongside me this would have some hope of actually happening?
I have been thinking about this for a while for the ColdFire targets.
In a few cases the drivers its uses are already devicetree enabled,
since they are used on some of the NXP/Freescale ARM SoC devices.
So this is interesting work to me.
The m68k mac platform is similar in this due to sharing some drivers
with ppc macs using Open Firmware. There are a few drivers where we
could eliminate complexity and #ifdef trickery if it was all
device tree based. For example, pmac_zilog.c relies on the data from
OF on a powermac but is getting platform data from the tables in
config.c on m68k. The code in via-cuda.c similarly looks up the
hardware info from OF on a powermac but has hard-coded data on m68k.
