Hi Greg, This series of patches cleans up the part of the 8250 device driver that is responsible for accessing the hardware registers. The driver defines all sorts of methods to do that right now, when it really should only support memory mapped and programmed I/O by default, and the latter only on PC-compatible platforms including those that have ISA/PCMCIA/PCI buses. The series shrinks the 8250 driver by about 10% in both binary and source code size, hopefully with no loss of functionality, and it allows platforms to no longer define bogus inb/outb functions when they don't provide CONFIG_HAS_IOPORT. I've build-tested for x86 and ARM with and without HAS_IOPORT. Hopefully Ralf can provide some feedback about the three MIPS platforms that have code changed by this. Arnd Arnd Bergmann (7): serial/8250: remove obsolete RM9000 port type serial/8250: move alchemy I/O handler to platform code serial/8250: move UPIO_TSI to powerpc serial/8250: move DWAP support to arch/mips serial/8250: remove obsolete and broken PORT_RSA support serial/8250: sanitize fourport handling serial/8250: make PIO support optional arch/mips/Kconfig | 7 - arch/mips/alchemy/common/platform.c | 50 +++ arch/mips/pmc-sierra/msp71xx/msp_serial.c | 32 ++- arch/powerpc/kernel/legacy_serial.c | 24 ++ drivers/tty/serial/8250.c | 472 +++-------------------------- drivers/tty/serial/8250.h | 8 + drivers/tty/serial/8250_hub6.c | 17 + drivers/tty/serial/Kconfig | 15 - drivers/tty/serial/serial_core.c | 4 - drivers/tty/serial/sunsu.c | 93 ------ include/linux/serial.h | 2 +- include/linux/serial_core.h | 10 +- include/linux/serial_reg.h | 51 --- 13 files changed, 171 insertions(+), 614 deletions(-) Cc: Ralf Baechle <ralf@xxxxxxxxxxxxxx> Cc: linux-serial@xxxxxxxxxxxxxxx Cc: Benjamin Herrenschmidt <benh@xxxxxxxxxxxxxxxxxxx> -- 1.7.5.4 -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
