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

2021-06-02T11:36:17+00:00

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.

We should try other FDT drivers when we see SBI_ENODEV returned by cold_init() of FDT driver. Signed-off-by: Anup Patel Reviewed-by: Atish Patra Reviewed-by: Xiang W

lib: utils/serial: Support Synopsys DesignWare APB UART

2021-05-19T07:33:19+00:00

Synopsys DesignWare APB UART is seen on the StarFive JH7100 SoC. Its programming interface is compatible with the existing 8250 UART driver. Simply add its compatible string to the driver makes it work with the StarFive JH7100 SoC on a BeagleV board. With this patch, the generic platform firmware can be used out of the box on the BeagleV board. Signed-off-by: Bin Meng Reviewed-by: Anup Patel

lib: utils/serial: Add support for Gaisler APBUART

2021-05-06T08:51:07+00:00

This patch adds support for the UART used by the NOEL-V processor. Cobham Gaisler's NOEL-V RISC-V processor IP is available under GPL and commercial license and is described in more detail at https://www.gaisler.com/noelv.

lib: sbi: Simplify console platform operations

2021-04-28T11:28:23+00:00

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: Fix shakti uart implementation
