Hi! Thanks for having a look at implementing this. > I have been studying the BCM2835 datasheet to familiarize myself with the I2C > device registers and their functionalities.

When you get to a state where you'd like us to take a look at it, that will be more convenient for us if you send it as a series of patches, rather than attaching individual source files to an email. (We have some notes about patch submission here https://www.qemu.org/docs/master/devel/submitting-a-patch.html if you haven't found that page already). thanks -- PMM
