* Blackfin: fix dma-mapping build errorsFUJITA Tomonori2009-06-221-0/+13
| | | | | | | | | | The recent deprecation of dma_sync_{sg,single} ironically broke Blackfin systems. This is because we don't define dma_sync_sg_for_cpu at all, so until the DMA asm-generic conversion/cleanup is done after the next release, simply stub out the dma_sync_sg_for_{cpu,device} functions.

* Blackfin: drop BF535-specific text for exception 0x2A (unaligned instruction)Yi Li2009-06-221-3/+1
| | | | | | | | | We don't support the BF535 at all, and the exception 0x2A text specific to it is pretty verbose and confusing (since the behavior is simply odd), so punt it to keep the noise down. Signed-off-by: Yi Li <yi.li@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: fix early crash when booting on wrong cpuRobin Getz2009-06-221-8/+15
| | | | | | | | | | Make sure we process the kernel command line before poking the hardware, so that we can process early printk. This helps ensure that if you boot a kernel configured for a different processor, something will be left in the log buffer.

* Blackfin: unify memory map headersMike Frysinger2009-06-2216-350/+145
| | | | | | | | | | Many aspects of the Blackfin memory map is exactly the same across all variants. Rather than copy and paste all of these duplicated values in each header, unify all of these into the common Blackfin memory map header file. In the process, push down BF561 SMP specific stuff to the BF561 specific header to keep the noise down. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: stick the CPU name into boot image nameRobin Getz2009-06-221-1/+1
| | | | | | | | | | | Rather than use "Linux" in the boot image name (as this is redundant -- the image type is already set to "linux"), use the CPU name. This makes it fairly obvious when a wrong image is accidentally booted. Otherwise there is no kernel output and you waste time scratching your head wondering wtf just happened.

* Blackfin: decouple unrelated cache settings to get exact behaviorJie Zhang2009-06-2211-81/+176
| | | | | | | | | | | | | | | The current cache options don't really represent the hardware features. They end up setting different aspects of the hardware so that the end result is to turn on/off the cache. Unfortunately, when we hit cache problems with the hardware, it's difficult to test different settings to root cause the problem. The current settings also don't cleanly allow for different caching behaviors with different regions of memory. So split the configure options such that they properly reflect the settings that are applied to the hardware.

* Blackfin: fix accidental reset in some boot modesSonic Zhang2009-06-221-1/+2
| | | | | | | | | | | | 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: simplify irq stack overflow checkingMike Frysinger2009-06-221-15/+17
| | | | | | | 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: redo handling of bad irqsMike Frysinger2009-06-221-42/+11
| | | | | | | | | | 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: bf518f-ezbrd: update DSA resourcesMike Frysinger2009-06-221-5/+11

* Blackfin: unify memory region checks between kgdb and trapsMike Frysinger2009-06-224-274/+256
| | | | | | | | | 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.

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.
