Perhaps a pch_phub.bios_uartclk parameter could be used for setting up the initial console and once the phub driver is loaded, it can make the necessary changes and fix things up in the uart port? This would add a binding between the pch_uart and pch_phub code. Thoughts? -- Darren Hart Intel Open Source Technology Center Yocto Project - Linux Kernel
