[Qemu-devel] [PATCH 0/7] serial: add serial_chr_nonnull()

[Philippe Mathieu-Daudé]

Hi,

This series add the serial_chr_nonnull() which connect to the "null" chardev
backend if none is provided.

Inspired by Peter's suggestion:
http://lists.nongnu.org/archive/html/qemu-devel/2017-08/msg05987.html
which also refers to this issue:
http://lists.nongnu.org/archive/html/qemu-devel/2017-08/msg03546.html

Some boards still check serial_hds[x] non null before calling serial_mm_init(),
this check could now be removed on the SoC which always have an UART mapped.

This might be a follow up if this series is accepted.

Regards,

Phil.

  serial: add serial_chr_nonnull() to use the null backend when none provided
  serial: use serial_chr_nonnull() in serial_mm_init()
  hw/arm/fsl_imx*: use serial_chr_nonnull()
  hw/mips/malta: use serial_chr_nonnull()
  hw/char/exynos4210_uart: use serial_chr_nonnull()
  hw/char/omap_uart: serial_mm_init() already check for null chr
  hw/xtensa: serial_mm_init() already check for null chr
