i2c on mpc850

Hello, I have a custom board (with an atmel microcontroller) over a rpxlite dw (mpc850) running linux. I want them to talk i2c to each other. I would like anyone of them to be able to initiate communication. The MPC850 is multimaster-capable. But i don't believe this feature is implemented in the linux kernel (i2c-algo-8xx.c). Am I right? If so, what is the best way of emulating multimaster mode? I thought a simple way of doing so would be for the custom board cto ause an interrupt which would trigger a i2c master-read command, therefore keeping the linux board in master-only mode and the atmel one in slave-only mode... Any comment/suggestion? Best regards, Patrick Mahoney ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
