At present only the core UART functions (data path for tx/rx) are implemented, which is enough for UEFI to boot. The following features/registers are unimplemented: * Line/modem control * Scratch register * Extra control * Baudrate * SPI interfaces Signed-off-by: Andrew Baumann <Andrew.Baumann@microsoft.com> Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Message-id: 1457467526-8840-3-git-send-email-Andrew.Baumann@microsoft.com Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
