From 6bd1fbea2e8bff9346a5afb44ca948b4e4ed74a5 Mon Sep 17 00:00:00 2001 From: Sonic Zhang Date: Wed, 9 Sep 2009 10:46:19 +0000 Subject: Blackfin: move on-chip UART resources to boards files Rather than keeping the pins in the actual driver and worrying about a mess of Kconfig options, declare all the desired pin resources in the boards file. This lets people easily select the specific pins/ports for the normal UART as well as GPIOs for CTS/RTS.
