serial: 8250: Add Quark X1000 to 8250_pci.c
commit 1ede7dcca3c4fa15a518ab0473126f9c3e621e4c upstream. Quark X1000 contains two designware derived 8250 serial ports. Each port has a unique PCI configuration space consisting of BAR0:UART BAR1:DMA respectively. Unlike the standard 8250 the register width is 32 bits for RHR,IER etc The Quark UART has a fundamental clock @ 44.2368 MHz allowing for a bitrate of up to about 2.76 megabits per second. This patch enables standard 8250 mode Signed-off-by: Bryan O'Donoghue <pure.logic@nexus-software.ie> Reviewed-by: Heikki Krogerus <heikki.krogerus@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
