This series adds a few more features to the debug UART, making it possible to use it even when the board needs to perform additional init for the UART to work. The debug UART is anabled on link.
Some minor PCI tidy-ups are also included.
Link currently does not boot due to lack of early malloc() memory. For now just increase the size.
