lib: utils/serial: Use fdt_driver for initialization

2024-11-28T12:22:58Z

The serial driver subsystem does not need any extra data, so it can use `struct fdt_driver` directly. The generic fdt_serial_init() first attempts to match the chosen stdout device, and upon failure matches the first available serial device in the DT. It is a fatal error if no such device is found. This matches the behavior of fdt_driver_init_one(). Signed-off-by: Samuel Holland Reviewed-by: Anup Patel

lib: utils/serial: Pass the FDT to fdt_serial_init()

2024-08-24T07:33:01Z

Indicate that this function does not modify the FDT blob, and deduplicate the call to fdt_get_address(). Signed-off-by: Samuel Holland Reviewed-by: Andrew Jones Reviewed-by: Anup Patel

lib: utils/serial: Constify FDT pointers in parsing functions

Indicate that none of these functions modify the devicetree by constifying the parameter type. Signed-off-by: Samuel Holland Reviewed-by: Andrew Jones Reviewed-by: Anup Patel

lib: utils/serial: Use kconfig for enabling/disabling drivers

2022-08-08T04:03:21Z

We update serial drivers makefile to use kconfig for enabling/disabling drivers. To avoid compile errors, we also enable appropriate serial drivers for each platform. Signed-off-by: Anup Patel Tested-by: Andrew Jones Acked-by: Atish Patra Tested-by: Atish Patra

lib: sbi: Simplify console platform operations

2021-04-28T11:28:23Z

Instead of having console_putc() and console_getc() callbacks in platform operations, it will be much simpler for console driver to directly register these operations as device to the sbi_console implementation. Signed-off-by: Anup Patel Reviewed-by: Alistair Francis Reviewed-by: Xiang W

lib: utils: Add simple FDT serial framework

2020-05-01T04:32:39Z

We add simple serial framework which will select and use serial driver based on details in FDT passed by previous booting stage. Signed-off-by: Anup Patel Reviewed-by: Atish Patra
