It looks OK apart from the naming. Could we call it "yosemite2-bmc" instead ?

Thanks,

The same routine name is proposed in the tiogapass patch :

   https://lore.kernel.org/qemu-devel/20230210122641.837614-1-pkarthikeyan1509@gmail.com/

Do you have plans to populate the I2C buses differently ?

same as tiogapass ?

The RAM size is the only difference with the tiogapass and one could use the
-m machine option instead.
