I don't think it is documented somewhere that the IP comes from Synopsis Designware. I noticed this when I was working on Intel Quark support, that lots of IPs on Intel Quark are from Synopsis (eg: we have the Synopsis Designware ethernet driver working on Intel Quark). > >> It is possible we can reuse >> U-Boot Synopsis I2C driver on Intel platform, with adaptations to PCI. > > > I can definitely look into this. Thanks for letting me know. Regards, Bin _______________________________________________ U-Boot mailing list [email protected] http://lists.denx.de/mailman/listinfo/u-boot
