Enable the UPF_BOOT_AUTOCONF flag in serial_omap_probe().
This will cause serial_omap_config_port() to be run and
the hardware to correctly be flagged as supporting hardware
and software flow-control.
Without this, it is not possible to enable flow control.

Subject: [PATCH] Enable OMAP UART port UPF_BOOT_AUTOCONF auto-configuration
Enable the UPF_BOOT_AUTOCONF flag in serial_omap_probe().
This will cause serial_omap_config_port() to be run and
the hardware to correctly be flagged as supporting hardware
and software flow-control.
Without this, it is not possible to enable flow control.
