-Subject: [PATCH RFC 3/3] MIPS: AR7: ensure the port type's FCR value is used
-
-Since commit aef9a7bd9b67 ("serial/uart/8250: Add tunable RX interrupt
-trigger I/F of FIFO buffers"), the port's default FCR value isn't used
-in serial8250_do_set_termios anymore, but copied over once in
-serial8250_config_port and then modified as needed.
-
-Unfortunately, serial8250_config_port will never be called if the port
-is shared between kernel and userspace, and the port's flag doesn't have
-UPF_BOOT_AUTOCONF, which would trigger a serial8250_config_port as well.
-
-This causes garbled output from userspace:
-
-[ 5.220000] random: procd urandom read with 49 bits of entropy available
-ers
- [kee
-
-Fix this by forcing it to be configured on boot, resulting in the
-expected output:
-
-[ 5.250000] random: procd urandom read with 50 bits of entropy available
-Press the [f] key and hit [enter] to enter failsafe mode
-Press the [1], [2], [3] or [4] key and hit [enter] to select the debug level
-
-Fixes: aef9a7bd9b67 ("serial/uart/8250: Add tunable RX interrupt trigger I/F of FIFO buffers")

----
-I'm not sure if this is just AR7's issue, or if this points to a general
-issue for UARTs used as kernel console and login console with the "fixed"
-commit.
