2011-03-18Blackfin: SMP: work around anomaly 05000491Sonic Zhang
In order to safely work around anomaly 05000491, we have to execute IFLUSH from L1 instruction sram. The trouble with multi-core systems is that all L1 sram is visible only to the active core. So we can't just place the functions into L1 and call it directly. We need to setup a jump table and place the entry point in external memory. This will call the right func based on the active core. In the process, convert from the manual relocation of a small bit of code into Core B's L1 to the more general framework we already have in place for loading arbitrary pieces of code into L1.

2011-03-18Blackfin: split optimization settings moreMike Frysinger
We need to place icache flush funcs into L1 inst sram to work around a hardware anomaly. But this currently breaks SMP support as the L1 inst sram is per-core and cannot be called directly. So in preparation for making that work, split the two options. Further, split out the SMP depend so that we can allow some for SMP. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2010-08-06Blackfin: allow cache funcs to be in L1 for IFLUSH Anomaly 05000491Mike Frysinger
Anomaly 05000491 says that IFLUSH cannot have certain types of memory stalls triggered before it has completed in order to function correctly. One such condition is that it be in L1 instruction. So add a config option to move it there, default it to on, and throw up a warning when it is turned off and this anomaly exists. Since the anomaly should be worked around, we can drop the older method of calling IFLUSH multiple times.

2010-05-22Blackfin: move string functions to normal lib/ assemblyRobin Getz
Since 'extern inline' doesn't work correctly in the context of the Linux kernel (too many overriding defines), move the string functions to normal lib/ assembly files (like the existing mem funcs). This avoids the forced inline all over the kernel and allows us to place them constantly in L1. This also avoids some module failures when gcc inserts calls to string functions but the kernel build system doesn't fully consult the library archives.

2010-05-21Blackfin: punt Blackfin-specific GPIO wakeup APIMichael Hennerich
This patch removes a custom GPIO wakeup API which allowed GPIOs to act as wakeup sources, which are not configured as Interrupts. This API is a leftover from the time before irq_wake was established. From now on people must use enable_irq_wake(GPIO_IRQx) and the GPIO in question needs to be configured as Interrupt.

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.

2009-12-15module: make MODULE_SYMBOL_PREFIX into a CONFIG optionAlan Jenkins
The next commit will require the use of MODULE_SYMBOL_PREFIX in .tmp_exports-asm.S. Currently it is mixed in with C structure definitions in "asm/module.h". Move the definition of this arch option into Kconfig, so it can be easily accessed by any code. This also lets modpost.c use the same definition. Previously modpost relied on a hardcoded list of architectures in mk_elfconfig.c. A build test for blackfin, one of the two MODULE_SYMBOL_PREFIX archs, showed the generated code was unchanged. vmlinux was identical save for build ids, and an apparently randomized suffix on a single "__key" symbol in the kallsyms data).

Convert Blackfin to use GENERIC_TIME via the arch_getoffset() infrastructure, reducing the amount of arch specific code we need to maintain. I've taken my best swing at converting this, but I'm not 100% confident I got it right. My cross-compiler is now out of date (gcc4.2) so I wasn't able to check if it compiled.
