* serial: Add lpuart32 driverSascha Hauer2023-11-171-0/+1
| | | | | | | | This adds a lpuart32 driver. This is a variant of the lpuart driver that is found on i.MX9 and other SoCs. Link: https://lore.barebox.org/20231110125800.1901232-15-s.hauer@pengutronix.de Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* nios2: remove arch remains from driversDenis Orlov2023-07-031-2/+0
| | | | | | | | | | | The architecture was removed back in the commit efccc13513, however some drivers that were available exclusively for NIOS2 were left over. As it has been impossible to compile those since then, it seems reasonable to just get rid of them.

* serial: add basic VirtIO console driverAhmad Fatoum2021-02-221-0/+1
| | | | | | | | | | | | | | | | | | With this driver enabled, -device virtio-serial-device can now be passed to Qemu for barebox to detect a VirtIO console device. If barebox is passed as argument to the Qemu -kernel option, no device tree changes are necessary. Example: $ qemu-system-arm -m 256M -M virt -nographic \ -kernel build/images/barebox-dt-2nd.img \ -device virtio-serial-device \ -chardev socket,path=/tmp/foo,server,nowait,id=foo \ -device virtconsole,chardev=foo,name=console.foo Signed-off-by: Ahmad Fatoum <ahmad@a3f.at> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* serial: add support for PCI NS16550 UARTsAhmad Fatoum2019-12-091-0/+1
| | | | | | | | | | | | | | | | | | | | | | | This ports over the Linux v5.4 8250_pci driver. Unlike Linux, the barebox ns16550 implementation provides less hooks for covering all the quirky behavior of all the different 8250-"compatible" hardware blocks. The barebox driver matches against all serial port the Linux driver does, but for hardware with quirks that can't be expressed in the current barebox n16550 API, the probe fails with -ENOSYS and an appropriate message telling that the quirk handling is missing. This should make future extension of the driver straight-forward. Unlike the kernel variant of the driver, most ->exit quirk callbacks can be dropped in barebox as they often disable IRQs, which we do in the ->init anyway. This was tested with the EFI PCI driver on qemu with the options: -device pci-serial,chardev=cdev0 -chardev file,id=cdev0,path=COM Signed-off-by: Ahmad Fatoum <a.fatoum@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | So now we can stop to use the efi-stdio as this driver print on the Framebuffer and the serial at the same time. This is specially usefull if we want to use the framebuffer via efi-gop for something else. Do not forget to disable the efi-stdio device before enabling the console otherwise you will get double printing.
