Hi all,
I've been trying hard to make the mtd-partitions available via device
tree on my MPC8343 local bus.
No success so far ...
Everything works fine on my MPC5200B based system - flash layout
definition is quite simple ....
To me it looks like there's a problem regarding the local bus in general.
Am I missing a "compatible" or anything else ? "reg" or "ranges" ?
The other boards use static map files or provide partition over command
line args .... so suitable dts available.
Flash is 8MB size in 16-Bit configuration and should reside on
0xFF800000 at cs0.
Any hints ?
regards,
