2010-03-09Blackfin: increase NR_IRQS beyond NR on-chip IRQsMichael Hennerich
This makes room for off-chip IRQ controllers. Signed-off-by: Michael Hennerich <michael.hennerich@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-03-09Blackfin: fill out the signal si_addr when sending a SIGBUS/SIGSEGVBarry Song
Some userspace applications use this member in diagnosing crashes. It also makes some LTP tests pass (i.e. the Blackfin arch behaves more like everyone else). Signed-off-by: Barry Song <barry.song@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-03-09Blackfin: bf537-stamp: move ADF7021 MAC storage into platform resourcesMike Frysinger
Just generate a random MAC on the demo board since the ADF702x lacks dedicated storage for such things. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2010-03-09Blackfin: bf537-stamp: declare parallel flash as ROM with XIP kernelBarry Song
When the kernel is executing out of parallel flash (XIP), we can't have the flash go into an erase/programming cycle, otherwise the instruction fetching steps fail and everything crashes. Signed-off-by: Barry Song <barry.song@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2010-03-09Blackfin: fix up mm locking in address dumpingGraf Yang
The locking code in the address dumper needs to grab the mm's mmap_sem so that other CPUs do not get an inconsistent view. On UP systems this really wasn't a problem, but it is easy to trigger a race on SMP systems when another CPU removes a mapping.

This condition allowed only decoding of opcode 0x0040 Signed-off-by: Roel Kluin <roel.kluin@gmail.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-03-09Blackfin: initial XIP supportBarry Song
Signed-off-by: Barry Song <barry.song@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-03-09Blackfin: fix initial stack pointer setupBarry Song
During very early init, the stack pointer is given a slightly incorrect value (&init_thread_union). The value is later adjusted to the right one during early init (&init_thread_union + THREAD_SIZE), but it is used a few times in between. While the few functions used don't actually put things onto the stack (due to optimization), it's best if we simply use the right value from the start. Signed-off-by: Barry Song <barry.song@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-03-09Blackfin: fix the section name of init_thread_unionBarry Song
Use the common attribute rather than setting the section name directly. The common linker script defines expect the newer naming. Signed-off-by: Barry Song <barry.song@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-03-09Blackfin: replace harcoded define with proper THREAD_SIZE macroBarry Song
Signed-off-by: Barry Song <barry.song@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-03-09Blackfin: fix relocation errors with large initramfs imagesJie Zhang
Since we are now discarding .exit.text at runtime instead of link time, we need to place all .text sections ahead of the .data sections. Otherwise, a really large attached initramfs may cause link errors as it pushes the PC relative relocations behind the limits of the Blackfin ISA (~16meg). The instructions in the .exit.text are unable to call back into the .text sections leading to a link failure.

2010-03-09Blackfin: simplify SMP handling in SRAM codeYi Li
There is no need to use {get,put}_cpu() when we already have a spinlock to protect against multiple processors running simultaneously. Signed-off-by: Yi Li <yi.li@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-03-09Blackfin: SMP: add PM/CPU hotplug supportGraf Yang

2010-03-09Blackfin: SMP: make core timers per-cpu clock events for HRTYi Li
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.

2010-03-09Blackfin: drop cpu_callin_map on SMP systemsGraf Yang
Common API already provides functions for managing online CPUs. Signed-off-by: Graf Yang <graf.yang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-03-09Blackfin: SMP: add support for IRQ affinitySonic Zhang
Now that the Blackfin IRQ controller supports this, drivers get the normal functionality of controlling which CPU to bind IRQs to. Signed-off-by: Sonic Zhang <sonic.zhang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2010-03-09Blackfin: isram: add unlikely to sanity checksMike Frysinger

2010-03-09Blackfin: bf537-stamp: change CONFIG_USB_SL811_BFIN_IRQ to IRQ_PF4Mike Frysinger
The Kconfig option was never mainlined, so replace the define with the actual pin that it is hooked up to by default. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-03-09Blackfin: drop unused SL811 platform resources from bf527/pnav boardsMike Frysinger
These platforms don't hook up to this USB controller, so no point in declaring resources for it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2010-03-09Blackfin: gpio: use shorter nameMichael Hennerich
The gpio label size is 16 char, but the current code uses a longer name resulting in chopped display. So use a shorter name. Reported-by: Peter Meerwald <pmeerw@pmeerw.net> Signed-off-by: Michael Hennerich <michael.hennerich@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2010-03-09Blackfin: merge common CAN defines into one headersMike Frysinger

2010-03-09Blackfin: wire up the various memory related syscallsMike Frysinger
These all just go to the stub syscall at the moment, so this is largely future proofing. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-03-09Blackfin: SMP: enable HAVE_LEGACY_PER_CPU_AREAGraf Yang

2010-03-09Blackfin: MPU: handle caches for reserved memorySonic Zhang
We weren't handling the user-specified cache behavior for the reserved memory regions (via mem=/max_mem=). The no-MPU code already takes care of this, so add support to the MPU code as well. Signed-off-by: Sonic Zhang <sonic.zhang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2010-03-09Blackfin: fix MPU page permission masks overflow when dealing with async memoryBarry Song
Attempting to use the MPU while doing XIP out of parallel flash hooked up to the async memory bus would often result in random crashes as the MPU slowly corrupted memory. The fallout here is that the async banks gain MPU protection from user space too. So any accesses have to go through the mmap() interface rather than just using hardcoded pointers.

2010-03-09Blackfin: flush caches on SMP when one core calls another via IPIYi Li
Sometimes a SMP system will randomly panic at boot. This is due to caches being out of sync when one core tries to signal the other. So when one core calls another via IPI, flush the data caches. Signed-off-by: Yi Li <yi.li@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

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.
