* Blackfin: BF537: push down error masks to avoid namespace pollutionMike Frysinger2009-12-152-14/+10
| | | | | | | | | | The error masks are only needed in the BF537 demux error code, so instead of needing all the short peripheral defines in global space, push these masks into the one file where they are actually needed. This fixes a bunch of define collisions with common code (can/serial/etc...). Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Barry Song <barry.song@analog.com>
* Blackfin: SMP: don't start up core b until its state has been completely onlinedYi Li2009-12-152-18/+15
| | | | | | | | | | | | | | | | | | | | | | | | | 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: workaround anomaly 05000310Barry Song2009-12-151-0/+30
| | | | | | | | | | | | | While fetching instructions at the boundary of L1 instruction SRAM, a false External Memory Addressing Error might be triggered. We should ignore this and continue on our way to avoid random crashes. Because hardware errors are not exact in the Blackfin architecture, we need to catch a few more common cases when the code flow changes and the signal is finally delivered.

* Blackfin: drop ptrace() write support for fixed code/bootromMike Frysinger2009-12-151-13/+0
| | | | | | | | These regions are either read-only and won't work anyways (bootrom), or we don't want people screwing with them because they're shared between all processes (fixed code). Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: MPU: support XIP in async flash memoryBarry Song2009-12-151-4/+9
| | | | | | | | The NOMPU code already supported executing in the async banks, so this brings the MPU code in line. Signed-off-by: Barry Song <barry.song@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: drop 4KB reserve at end of memoryBarry Song2009-12-151-5/+0
| | | | | | | | | | | | | The point of this small chunk was to avoid anomaly 05000310. This never really seemed to do what it was intended though -- no valid CPLBs exist over the reserved memory, and there is often memory before it anyways (due to the uClinux MTD and/or reserved DMA region). Plus, it doesn't address the L1 instruction case. So drop this chunk as it wastes memory and is affront to humanity.

* Blackfin: support smaller uncached DMA chunks for memory constrained systemsBarry Song2009-12-153-7/+25
| | | | | | | | | When working with 8 meg systems, forcing a 1 meg DMA chunk heavily cuts into the available resources. So support smaller chunks to better cover needs for these systems. Signed-off-by: Barry Song <barry.song@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: push BF5Xx configs down into mach-specific KconfigsMike Frysinger2009-12-155-37/+37
| | | | | | | | While we're moving the BF54x code, have the BF54xM variants select the normal BF54x values so that the rest of the Kconfig tree doesn't need to check the BF54xM variant everytime it wants to check the BF54x. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: finish_atomic_sections: optimize the RTS stepMike Frysinger2009-12-151-7/+11
| | | | | | | No point in returning to userspace just to have it immediately perform the RTS step. We have to update the PC anyways, so do the RTS too. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* Blackfin: punt dead/unused flash mem_init settingsMike Frysinger2009-12-151-153/+0
| | | | | | | | I don't think these defines were ever used. At any rate, we have common bit defines for all parts as well as a Kconfig option to declare the EBIU async timings, and no one has really complained about this so far. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: gptimers: use unsigned timer/group idsMike Frysinger2009-12-152-32/+32
| | | | | | | | Since we always use these ids as unsigned values, and we have some assert code to make sure they don't exceed a limit, avoid signed issues. Reported-by: Roel Kluin <roel.kluin@gmail.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: don't walk VMAs when oopsingRobin Getz2009-12-151-0/+9
| | | | | | | | | | If we're double faulting, then we have to assume the VMAs are not safe as broken pointers here will prevent full trace output for the double fault. Shouldn't be a big problem though as rarely is a double fault caused by code in userspace. Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* Blackfin: BF54x: punt useless "masks" for count/address MMRsMike Frysinger2009-12-151-104/+0

* Blackfin: convert DMA mutex to an atomic and drop redundant codeMike Frysinger2009-12-152-35/+13
| | | | | | | | | | | The DMA channel status field was encoding redundant info wrt the DMA MMR config register, and it was doing an incomplete job of checking all DMA channels (some drivers write directly to the config register). So drop the tristate field in favor of a binary atomic field. This simplifies the code in general, removes the implicit need for sleeping, and forces the suspend code to handle all channels properly.
