lib: utils/serial: Add support for Altera JTAG UART

2026-02-20T11:20:35Z

Altera provides a JTAG UART core that provides virtual UART over JTAG and can coexist with their virtual JTAG. [1] This core has already been supported by Linux and the programming interface has always been stable. Add support for it to OpenSBI to ease JTAG prototype bringing up. The driver follows the device tree binding in mainline Linux.

Makefile: change to using .carray.c for carray files

2024-07-04T06:41:45Z

We would like to clean any files generated by the carray scripts by just searching for the filename as the current make system turns f.carray into f.o. Change to make the make system turn f.carray into f.carray.o note, command to go through .mk files changing the .o in the .mk files is: find . -type f -name "*.carray" | xargs -t -I fname /bin/bash -x -c ' fn=`basename -s .carray fname`; echo "$fn"; sed -i `dirname fname `/objects.mk -e s/"$fn".o/"$fn".carray.o/g' Link: https://patchwork.ozlabs.org/project/opensbi/patch/20240401213438.590209-2-ivan.orlov0322@gmail.com/ Reported-by: Ivan Orlov Suggested-by: Andrew Jones Signed-off-by: Ben Dooks Reviewed-by: Andrew Jones Reviewed-by: Anup Patel
