anyone used i2c-algo-8260 for the MPC8272 family?

Hi all,

I'm trying to get i2c-algo-8260 and i2c-pm826 working on an MPC8247.
It doesn't... It just hangs the kernel.

There are some subtle differences b/t the 8260 family and 8272 family.
The 8272 family only has 8KB DPRAM (c.f. 16KB), so I believe the
definition of PROFF_I2C in include/linux/cpm_8260.h should be
different.  I've changed it from:

	#define PROFF_I2C	((16 * 1024) - 64)
to 
	#define PROFF_I2C	((8 * 1024) - 64)

but still get no I2C activity, and a kernel hang.

Anyone have this working, or any thoughts to contribute?

Regards,
Ron Kellam.
