After the UART was initialized, we may still have bogus data in the
RX queue if it was enabled with incorrect pin muxing before.So let's flush the RX queue whenever we initialize baud rates.
This fixes a regression with the dynamic pinmuxing code when enable_uart=1
is not set in config.txt on Raspberry Pis that use pl011 for serial.Fixes: caf2233b28 ("bcm283x: Add pinctrl driver")

Commit 608b0c4ad4e5ec0c ("serial: Use next serial device if probing fails")
added code to search for more serial devices if the default one was not
probed correctly.Unfortunately, that breaks omap3_evm. So while investigating why that is
the case, let's disable the full search for everyone but bcm283x where it
is needed.Fixes: 608b0c4ad4e5ec0c ("serial: Use next serial device if probing fails")

On bcm2835 we need to ensure we only access serial devices that are
muxed to the serial output pins of the pin header. To achieve this
for the pl011 device, add a bcm2835 specific pl011 wrapper device
that does this check but otherwise behaves like a pl011 device.Signed-off-by: Alexander Graf

We want to use Kconfig logic to depend on whether pl01x devices

The bcm283x mini-uart is only really usable as U-Boot serial output
when it is muxed to the UART pins of the RPi pin header.So fail probing in case it is not muxed correctly, as in that case
firmware did not initialize it properly either.Signed-off-by: Alexander Graf
-
The serial initialization doesn't always quite work for me, so let's
always skip it for now. We know that firmware on the RPi initializes
us properly already.Signed-off-by: Alexander Graf

The fdtdec API got deprecated in favor of dev_read calls.
Use those instead.Signed-off-by: Alexander Graf

We are switching to a model where a serial device doesn't even get probed when
it's not muxed properly, so we don't need device specific disabling
functionality anymore.Signed-off-by: Alexander Graf
-
Currently our serial device search chokes on the fact that the serial
probe function could fail. If it does, instead of searching for the next
usable serial device, it just quits.This patch changes the fallback logic so that even when a serial device
was not probed correctly, we just try the next ones until we find one that
works.Signed-off-by: Alexander Graf

In U-boot, serial_tstc was use to determine is there have a character in
serial console that pending for read. If there is no "pending" function
implemented in serial driver, the serial-uclass will return "true(1)"
to indicate there have a character pending to read.Thus, read a character from nulldev serial will result in continuous
getting -EAGAIN return which might lead system to hang.This commit is to fix a bug in nulldev serial which implement "pending"
function in nulldev serial to always indicate there is no character in
console that pending for read.Signed-off-by: Wilson Lee
