Hi,
How do I disable the internal PCI arbiter:
--- 8< 8< 8< ---
PCI async ext clock used, internal PCI arbiter enabled
--- 8< 8< 8< ---
I hoped disabling CFG_CMD_PCI would do it, but no?!
BR,
Martin Egholm

Found it (I most likely guess) - in "include/ppc405.h":
#define CPC0_PCI_ARBIT_EN 0x00000001
I guess this should be done automatically if CFG_CMD_PCI is not defined?

No comments?
According to the PPC405EP datasheet the internal PCI arbiter should be
disabled if the PCI is unused.
