2014-06-03	f20bcf9 Browse files » serial: imx: Fix buggy transmissions when baudrate mismatches ... Bit 7 of UCR3 is described in the i.MX reference manuals (with the exception of i.MX1) as follows: ADNIMP: Autobaud Detection Not Improved-. Disables new features of autobaud detection (See Baud Rate Automatic Detection Protocol, for more details). 0 Autobaud detection new features selected 1 Keep old autobaud detection mechanism The "new features" mechanism occasionally causes the receiver to get out of sync and continuously produces received characters of '0xff'. In order to reproduce the problem: $ cs0.baudrate=19200 - Change the terminal baudrate to 19200 - Type in the console and it should look good - Change the terminal baudrate back to 115200 - Type 'b' in the console, then a stream of '0xff' is transmitted in loop Setting the ADNIMP bit avoids the transmission of '0xff' in loop. Also rename the bit definition as per the reference manual. Tested on mx6q. Based on a patch from Eric Nelson for U-boot.

As we have Omap specific init code anyway we can just set the register shift from there instead of relying on the devicetree properties.

2014-04-09	9f556d4 Browse files » x86: ns16550: Rework driver to allow for x86 I/O space ... 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.

2014-01-22	dac65f9 Browse files » console: Set Linux console parameter automatically ... 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.
