From b1524e29e318e79b2d04bcbd651a7af8dff32bb3 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Mon, 28 Sep 2009 03:16:01 +0000 Subject: Blackfin: bfin_serial.h: unify heavily duplicated serial code Each Blackfin port has been duplicating UART structures and defines when there really is no need for it. So start a new bfin_serial.h header to unify all these pieces and give ourselves a fresh start.

Sonic Zhang Date: Wed, 9 Sep 2009 10:46:19 +0000 Subject: serial: bfin_5xx: move resources into board files Rather than maintain Kconfig entries where people have to enter raw numbers and hardcode lists of addresses/pins in the driver itself, push it all to platform resources. This lets us simplify the driver, the Kconfig, and gives board porters greater flexibility. In the process, we need to also start supporting the early platform interface. Not a big deal, but it causes the patch to be bigger than a simple resource relocation. All the Blackfin boards already have their resources updated and in place for this change.
