[PATCH 0/3] debug_ll: Cleanup conflicts for multiple SoCs

[Sascha Hauer]

This cleans up some problems we have with debug_ll when it comes to
multi SoC images. debug_ll relies on having exactly one PUTC_LL()
implementation available. Most SoCs have their own DEBUG_*_UART Kconfig
option and the Kconfig choice around them makes sure only a single debug
UART can be selected. Some SoCs do not have a dedicated option though
and provide PUTC_LL() whenever the SoC is enabled which can to multiple
definitions of PUTC_LL(). Fix that by adding a DEBUG_*_UART option to
the SoC that currently do not have one.

Another problem is that pl011.h provides PUTC_LL() and
debug_ll_pl011_putc(). The former is needed when included indirectly
from debug_ll.h, the latter is needed by board code to specify a putc()
to the PBL console. This too ends up in multiple definitions of
PUTC_LL().

Both problems are fixed in this series

      debug_ll: give PUTC_LL a common prototype
      debug_ll: Add Kconfig options for debug uarts that have none
      debug_ll: pl011: define PUTC_LL only when requested
