* Blackfin: drop unused ISP1760 port1_disable from board resourcesMike Frysinger2009-06-22
| | | | | | | The port1 disable stuff was dropped from the USB ISP1760, so update the Blackfin boards accordingly. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: bf526-ezbrd: handle different SDRAM chipsGraf Yang2009-06-22

* Blackfin: unify memory map headersMike Frysinger2009-06-22
| | | | | | | | | | 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 Getz2009-06-22
| | | | | | | | | | | 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 Zhang2009-06-22
| | | | | | | | | | | | | | | 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 Zhang2009-06-22
| | | | | | | | | | | | 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: 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.

| | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 81933046ef2a615031c46171013bde2c5225ee69 ('mtd: Fix handling of mtdname in txx9ndfmc.c') introduced a potential memory leak. The 'mtdname' member of the private data structure is now allocated separately, but was not freed on certain error paths. Fix that, and make things simpler by _always_ allocating it separately so that we don't need 'if (mtdname != dev_name()) kfree(mtdname);'... which gets ugly now that we're doing it more than once, and more likely that we'll get it wrong some time.

It also adds concat support to physmap_of. This makes it possible to support e.g. the Intel P30 48F4400 chips which internally consists of 2 non-identical NOR chips on one die. Additionally partitions now can span over multiple chips. To describe such a chip's, multiple "reg" tuples are now supported in one flash device tree node.
