| * x86: ns16550: Rework driver to allow for x86 I/O spaceMichel Stam2014-04-091-16/+107
| | | | | | | | | | | | | | | | | | | | | | | | The current implementation fakes a memory-mapped I/O device at 0x3f8 and 0x2f8, then uses platform read/write functions to do the actual reading and writing. These platform functions only exist for the x86 platform; better to move the I/O routines into the driver and have the driver request I/O ports using request_ioport_region.

* | serial: ns16550: omap: set register shift from codeSascha Hauer2014-04-281-0/+4
|/ | | | | | | | The upstream dts files do not contain the register shift. As we have Omap specific init code anyway we can just set the register shift from there instead of relying on the devicetree properties. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * console: Set Linux console parameter automaticallySascha Hauer2014-01-222-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Linux specifies the linux,stdout-path property in the /chosen node in the devicetree. Unfortunately this is ignored in most cases. For cases in which barebox uses this property for its own use we translate this into a Linux boot arg with: - the console name provided by the serial driver - the the instance from the 'serial' alias - the baudrate from the actual baudrate. So with this it's for devicetee enabled boards no longer necessary to manually assign a console= parameter. Should a user not want to use the automatically assigned parameter it should do: global.linux.bootargs.console= in the environment. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

As some STMP devices are also found on i.MX6 move the common infrastructure out of MXS specific files and use the stmp_ prefix. This is done in preparation for i.MX6 NAND support.
