[U-Boot] CONFIG_MODEM_SUPPORT / CONFIG_HWFLOW still in use?

[David Müller (ELSOFT AG)]

Hello

While trying to convert the serial_s3c24x0.c driver to DM, I noticed
that no offical U-Boot configuration seems to be using the
CONFIG_MODEM_SUPPORT or CONFIG_HWFLOW option.

Do you know if these two options are still in use somewhere else? Or can
all the references to these options be removed irrevocably?
