linux.git/arch/nios2/Kconfig.debug, branch v4.13 Linux kernel source tree nios2: enable earlycon support 2017-05-08T08:59:19+00:00 Tobias Klauser tklauser@distanz.ch 2017-04-03T03:09:04+00:00 44a4ed42576da5f3387005a1667cb3e7aedfd687 Enable generic earlycon support for nios2. This e.g. allows to use a 8250/16650 UART as earlycon. In order to get the earlycon, we just need to call parse_early_param() in early_init_devtree() as soon as the device tree is initially scanned. By adding an stdout-path property to the dts (done in this patch for 10m50_devboard), the earlycon can be used. In order to provide early printk support, we need to provide a dummy implementation of early_console_write(), so that arch/nios2/kernel/early_printk.c can still be compiled if neither SERIAL_ALTERA_JTAGUART_CONSOLE nor SERIAL_ALTERA_UART_CONSOLE is selected. As soon as the altera_uart and altera_jtaguart support earlycon, the entire file can be removed.

Enable generic earlycon support for nios2. This e.g. allows to use a
8250/16650 UART as earlycon.

In order to get the earlycon, we just need to call parse_early_param()
in early_init_devtree() as soon as the device tree is initially scanned.
By adding an stdout-path property to the dts (done in this patch for
10m50_devboard), the earlycon can be used.

In order to provide early printk support, we need to provide a dummy
implementation of early_console_write(), so that
arch/nios2/kernel/early_printk.c can still be compiled if neither
SERIAL_ALTERA_JTAGUART_CONSOLE nor SERIAL_ALTERA_UART_CONSOLE is
selected. As soon as the altera_uart and altera_jtaguart support
earlycon, the entire file can be removed.
