Thanks - modifications like adding some peripherals required recompiling qemu and can't be achieved with some command line arguments/configuration? This will require an update of the Zephyr SDK. |

This enables more use-cases, including separation of debug output from interaction with the platform via serial port, SLIP-based networking and probably much more. Originally introduced here: foss-for-synopsys-dwc-arc-processors/qemu#62 Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>

This makes the second UART of ARC QEMU's "virt" platfrom available in Zephyr. But please note to get it used corresponding change needs to be applied to QEMU itself, see: foss-for-synopsys-dwc-arc-processors/qemu#62 PR for Zephyr's SDK-NG is posted here: zephyrproject-rtos/sdk-ng#422 Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>

In some cases it's really useful to have more than 1 UART interface. For example: * Use one UART for debug output while the second for interaction with the virtual platform. * Use one of UART's as a mean for packe communication (i.e. SLIP) That was originally requested by Zephyr users here: https://lists.zephyrproject.org/g/devel/message/8285 Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>

@cupertinomiranda please consider merging this one as we need that in Zephyr SDK! |
|
This will be merged when all of the recent changes get stabilized. |

Sorry for the delay. @abrodkin did not want to delete the branch which is in your name. Please do it so, if you think it is Ok. |
