2024-06-13lib: utils/serial: Fix fdt_serial to match more dt nodesXiang W1-13/+13
If there are multiple dt nodes, the previous code only tries to match the first one, which may lose initialization. Signed-off-by: Xiang W <wxjstz@126.com> Reviewed-by: Anup Patel <anup@brainfault.org>
2024-06-13lib: utils/serial: Skip initialize serial when dt is not enabledXiang W1-0/+7
When the dt node has a status property and the value is not ok or okay, skip initializing serial. Signed-off-by: Xiang W <wxjstz@126.com> Reviewed-by: Anup Patel <anup@brainfault.org>
2023-05-26lib: utils: Improve fdt_serial_initXiang W1-31/+17
A final check of all DT nodes does not necessarily find a match, so SBI_ENODEV needs to be returned. Optimize removal of current_driver. Signed-off-by: Xiang W <wxjstz@126.com> Reviewed-by: Anup Patel <anup@brainfault.org>
2022-05-13lib: utils/serial: Generate FDT serial driver list at compile-timeAnup Patel1-21/+7
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 <apatel@ventanamicro.com> Reviewed-by: Atish Patra <atishp@rivosinc.com>
2022-02-28lib: utils: serial: Initial commit of xlnx-uartliteAlistair Francis1-1/+3
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.

This simply adds an helper to get fdt address which is more explicit than sbi_scratch_thishart_arg1_ptr. Signed-off-by: Alexandre Ghiti <alexandre.ghiti@canonical.com> Reviewed-by: Xiang W <wxjstz@126.com> Reviewed-by: Anup Patel <anup.patel@wdc.com>
2021-06-02lib: utils: consider ':' in stdout-pathHeinrich Schuchardt1-3/+12
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.
