* Blackfin: SMP: make core timers per-cpu clock events for HRTYi Li2010-03-092-0/+20
| | | | | | | | | | | | | | | SMP systems require per-cpu local clock event devices in order to enable HRT support. One a BF561, we can use local core timer for this purpose. Originally, there was one global core-timer clock event device set up for core A. To accomplish this feat, we need to split the gptimer0/core timer logic so that each is a standalone clock event. There is no requirement that we only have one clock event source anyways. Once we have this, we just define per-cpu clock event devices for each local core timer.

* Blackfin: move on-chip UART resources to boards filesSonic Zhang2010-03-093-16/+131
| | | | | | | | | | 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.

* Blackfin: SMP: don't start up core b until its state has been completely onlinedYi Li2009-12-151-10/+7
| | | | | | | | | | | | | | | | | | | | | | | | | When testing PREEMPT_RT kernel on BF561-EZKit, the kernel blocks while booting. When the kernel initializes the ethernet driver, it sleeps and never wakes up. The issue happens when the kernel waits for a timer for Core B to timeout (the timers are per-cpu based: static DEFINE_PER_CPU(struct tvec_base *, tvec_bases) = &boot_tvec_bases). However, the ksoftirqd thread for Core B (note, the ksoftirqd thread is also per-cpu based) cannot work properly, and the timers for Core B never times out. When ksoftirqd() for the first time runs on core B, it is possible core A is still initializing core B (see smp_init() -> cpu_up() -> __cpu_up()). So the "cpu_is_offline()" check may return true and ksoftirqd moves to "wait_to_die". So delay the core b start up until the per-cpu timers have been set up fully.

* Blackfin: mass clean up of copyright/licensing infoRobin Getz2009-10-0717-322/+57
| | | | | | | | | | | | | | | | | | Bill Gatliff & David Brownell pointed out we were missing some copyrights, and licensing terms in some of the files in ./arch/blackfin, so this fixes things, and cleans them up. It also removes: - verbose GPL text(refer to the top level ./COPYING file) - file names (you are looking at the file) - bug url (it's in the ./MAINTAINERS file) - "or later" on GPL-2, when we did not have that right It also allows some Blackfin-specific assembly files to be under a BSD like license (for people to use them outside of Linux).

* Blackfin: cleanup sync handling when enabling/disabling cplbsYi Li2009-09-171-16/+4
| | | | | | | | | | | | | | The handling of updating the [DI]MEM_CONTROL MMRs does not follow proper sync procedures as laid out in the Blackfin programming manual. So rather than audit/fix every call location, create helper functions that do the right things in order to safely update these MMRs. Then convert all call sites to use these new helper functions. While we're fixing the code, drop the workaround for anomaly 05000125 as that anomaly applies to old versions of silicon that we do not support.

* Blackfin: improve double fault debug handlingGraf Yang2009-09-171-4/+4
| | | | | | | | | | | | | | Since the hardware only provides reporting for the last exception handled, and the values are valid only when executing the exception handler, we need to save the context for reporting at a later point. While we do this for one exception, it doesn't work properly when handling a second one as the original exception is clobbered by the double fault. So when double fault debugging is enabled, create a dedicated shadow of these values and save/restore out of there. Now the crash report properly displays the first exception as well as the second one. Signed-off-by: Graf Yang <graf.yang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
