lib: utils/serial: Generate FDT serial driver list at compile-time

2022-05-13T03:56:13Z

Instead of having FDT serial driver list hard-coded in the C source, we generate it using carray.sh at compile-time. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: utils: serial: Initial commit of xlnx-uartlite

2022-02-28T04:20:09Z

Initial commit of the xlnx-uartlite device and FDT support. This was tested by running OpenSBI on a modified QEMU virt machine using the xlnx-uartlite for serial. Signed-off-by: Alistair Francis Reviewed-by: Xiang W Reviewed-by: Anup Patel

lib: utils: Add LiteX UART support

2021-11-18T07:52:02Z

Add support for the UART provided by the LiteX SoC framework (https://github.com/enjoy-digital/litex), based on its FDT info (described in the Linux tree at Documentation/devicetree/bindings/serial/litex,liteuart.yaml). Signed-off-by: Gabriel Somlo Reviewed-by: Xiang W Reviewed-by: Anup Patel

include: sbi_utils: Introduce an helper to get fdt base address

2021-11-02T05:53:16Z

This simply adds an helper to get fdt address which is more explicit than sbi_scratch_thishart_arg1_ptr. Signed-off-by: Alexandre Ghiti Reviewed-by: Xiang W Reviewed-by: Anup Patel

lib: utils: consider ':' in stdout-path

2021-06-02T11:36:17Z

The value of the /chosen/stdout-path devicetree property is used to determine the UART used by openSBI. According to the devicetree specification the value may contain a hyphen, e.g. chosen { stdout-path = "/serial@f00:115200"; }; If the character ':' is present, it terminates the path of the device.
