* Blackfin: convert interrupt pipeline to irqflagsPhilippe Gerum2009-06-22
| | | | | Signed-off-by: Philippe Gerum <rpm@xenomai.org> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: allow people to select BF51x-0.1 silicon revMike Frysinger2009-06-22
| | | | | | Now that 0.1 of the BF51x is coming out, allow people to build for it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: bf526-ezbrd: set SPI flash resources to SST deviceGraf Yang2009-06-22
| | | | | | | The BF526-EZBRD has a SST SPI flash on it, not a ST Micro. Signed-off-by: Graf Yang <graf.yang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: fix accidental reset in some boot modesSonic Zhang2009-06-22
| | | | | | | | | | | | We read the SWRST (Software Reset) register to get at the last reset state, and then we may configure the DOUBLE_FAULT bit to control behavior when a double fault occurs. But if the lower bits of the register is already set (like UART boot mode on a BF54x), we inadvertently make the system reset by writing to the SYSTEM_RESET field at the same time. So make sure the lower 4 bits are always cleared. Signed-off-by: Sonic Zhang <sonic.zhang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: abstract irq14 lowering in do_irqMike Frysinger2009-06-22
| | | | | | | Split out the optional IRQ14 lowering code to further simplify the asm_do_IRQ() function and keep the ifdef nest under control. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: simplify irq stack overflow checkingMike Frysinger2009-06-22
| | | | | | | Take a page from x86 and abstract the stack checking out of the asm_do_IRQ() function so that the result is easier to digest. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: only build show_interrupts() when procfs is enabledMike Frysinger2009-06-22

* Blackfin: redo handling of bad irqsMike Frysinger2009-06-22
| | | | | | | | | | With the common IRQ code initializing much more of the irq_desc state, we can't blindly initialize it ourselves to the local bad_irq state. If we do, we end up wrongly clobbering many fields. So punt most of the bad irq code as the common layers will handle the default state, and simply call handle_bad_irq() directly when the IRQ we are processing is invalid.

* Blackfin: update anomaly listsMike Frysinger2009-06-22
| | | | | | Update anomaly headers to match latest released anomaly sheets. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: bf533-ezkit: add resources for FISP devicesMike Frysinger2009-06-22
| | | | | | | | The BF533-EZKIT has two Flash In-System Programming devices hooked up to the async memory bus, so add resources for the primary flashes and the SRAMs on the devices. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: bf518f-ezbrd: update DSA resourcesMike Frysinger2009-06-22
| | | | | | | The common DSA code changed structure layout, so update the BF518F-EZBRD resources accordingly. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: unify memory region checks between kgdb and trapsMike Frysinger2009-06-22
| | | | | | | | | The kgdb (in multiple places) and traps code developed pretty much identical checks for how to access different regions of the Blackfin memory map, but each wasn't 100%, so unify them to avoid duplication, bitrot, and bugs with edge cases.

* Blackfin: only build irqpanic.c when neededMike Frysinger2009-06-18
| | | | | | | | The irq_panic function is only used when CONFIG_DEBUG_ICACHE_CHECK is enabled, so move the conditional build to the Makefile rather than wrapping all of the contents of the file. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: pull in asm/io.h in ksyms for prototypesMike Frysinger2009-06-18
| | | | | | | Make sure we pull in asm/io.h when exporting symbols for the I/O functions so we don't end up with a build failure due to missing prototypes. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: use common test_bit() rather than __test_bit()Mike Frysinger2009-06-18
| | | | | | | Convert to test_bit() as that is what pretty much everyone uses and allows us to migrate asm/bitops.h to the asm-generic version. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

| * kmap_types: make most arches use generic header fileRandy Dunlap2009-06-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Convert most arches to use asm-generic/kmap_types.h. Move the KM_FENCE_ macro additions into asm-generic/kmap_types.h, controlled by __WITH_KM_FENCE from each arch's kmap_types.h file. Would be nice to be able to add custom KM_types per arch, but I don't yet see a nice, clean way to do that. Built on x86_64, i386, mips, sparc, alpha(tonyb), powerpc(tonyb), and 68k(tonyb). Note: avr32 should be able to remove KM_PTE2 (since it's not used) and then just use the generic kmap_types.h file. Get avr32 maintainer approval.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * create mm/init-mm.c, move init_mm there * remove INIT_MM, initialize init_mm with C99 initializer * unexport init_mm on all arches: init_mm is already unexported on x86. One strange place is some OMAP driver (drivers/video/omap/) which won't build modular, but it's already wants get_vm_area() export. Somebody should look there.

| | | | | | | | | | | | | | | | Most boards use 25000000 as the default HZ, so rather than add a whole bunch more boards, make it the default for everyone. This also fixes randconfig builds as there was no default before. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

| * Blackfin: punt unused/wrong mutex-dec.hMike Frysinger2009-06-13

| * Blackfin: add support for irqflagsMike Frysinger2009-06-13
| | | | | | | | | | | | | | | | This converts the irq handling in the Blackfin arch from the old irq.h / system.h method to the new irqflags.h. A stepping stone on the way to other tracing functionality. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

| * Blackfin: do not configure the UART early if on wrong processorRobin Getz2009-06-13
| | | | | | | | | | | | | | | | | | Before we configure the early UART, check to make sure we are running on the expected processor - otherwise, we cause problems by configuring pins that don't exist (and causing an infinite loop of faults).

| * Blackfin: fix deadlock in SMP IPI handlerSonic Zhang2009-06-13
| | | | | | | | | | | | | | | | | | | | | | | | | | When a low priority interrupt (like ethernet) is triggered between 2 high priority IPI messages, a deadlock in disable_irq() is hit by the second IPI handler. This is because the second IPI message is queued within the first IPI handler, but the handler doesn't process all messages, and new ones are inserted rather than appended. So now we process all the pending messages, and append new ones to the pending list.

| * Blackfin: push down exception oops checkingMike Frysinger2009-06-13
| | | | | | | | | | | | | | | | | | Rather than maintain a duplicate list of valid exceptions we can take in the kernel both in the first if() check and the switch() check, delay the oops check to after the switch(). All valid exceptions will have returned by this point leaving only the invalid ones. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
