* | x86: Add a simple superio driver for SMSC LPC47M | Bin Meng | 2014-12-13 | -0/+19 |
On most x86 boards, the legacy serial ports (io address 0x3f8/0x2f8) are provided by a superio chip connected to the LPC bus. We must program the superio chip so that serial ports are available for us. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org> |
