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

Hi Ron, 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)
