We have an item to get this fixed, but in the mean time, disable selection via Kconfig dependencies. Signed-off-by:

The handling of updating the [DI]MEM_CONTROL MMRs does not follow proper sync procedures as laid out in the Blackfin programming manual. So rather than audit/fix every call location, create helper functions that do the right things in order to safely update these MMRs. Then convert all call sites to use these new helper functions. While we're fixing the code, drop the workaround for anomaly 05000125 as that anomaly applies to old versions of silicon that we do not support. Signed-off-by:

I think we have to use the physical dimensions [mm] of the display for .width and .heigth in struct bfin_bf54xfb_mach_info bf54x_lq043_data which are copied to fbinfo->var.height/.width in bf54x-lq043fb.c. linux/fb.h describes this values as 'height/weight of picture in mm' Otherwise QT calcs the wrong dpi value and the displayed fonts are very small.

The interrupt probe workaround doesn't work without hacks to common code, and the add-on card only needs a simple resistor to fix the problem, so drop the board-specific hack. Signed-off-by:

Since the hardware only provides reporting for the last exception handled, and the values are valid only when executing the exception handler, we need to save the context for reporting at a later point. While we do this for one exception, it doesn't work properly when handling a second one as the original exception is clobbered by the double fault. So when double fault debugging is enabled, create a dedicated shadow of these values and save/restore out of there. Now the crash report properly displays the first exception as well as the second one. Signed-off-by:

One too many zeros means we run way faster than the codec can handle. Signed-off-by:

The protect_page() function was incorrectly setting up the hardware tables based on possible access capabilities rather than the actual requested values. This means we would grant more access to mmap-ed pages than we should have. Once we fix this, we need to tweak the signal generated by such accesses to aline ourselves with other ports. This allows the LTP mmap0{5,6,7} cases to run properly. Signed-off-by: -

The end of the stack may not be valid (and that could be OK), so do not attempt to parse it. If we do, we might use a bad pointer in kernel space which makes things panic(). Signed-off-by:

The initial BF54x port included some defines to keep code simple across different processors, but it just ended up causing the UART0 DMA IRQs to be set to the UART1 channels. Signed-off-by:

Allow hardware errors to be caught during early portions of booting, and leave something in the shadow console that people can use to debug their system with (to be printed out by the bootloader on next reset). This enables the hardare error interrupts in head.S, allowing us to find hardware errors when they happen (well, as much as you can with a hardware error) and prints out the trace if it is enabled. This will catch errors (like booting the wrong image on a 533) which previously resulted in a infinite loop/hang, as well as random hardware errors before before setup_arch(). To disable this debug only feature - turn off EARLY_PRINTK. Signed-off-by:

Add a memory based shadow console to keep a copy of the printk buffer in a location which can be found externally. This allows bootloaders to locate and utilize the log buffer in case of silent (early/resume/etc...) crashes. Signed-off-by:

The FDPIC arches support a standard set of ptrace requests so rather than define our own custom API, hook up those requests for common code to leverage. Signed-off-by: -

Rather than defining the locks and initializing them all the time, only do so when we actually need them (i.e. the SRAM regions exist). This avoids dead data and code bloat during runtime. Signed-off-by: -

The current module relocation code has spotty handling wrt different memory regions (like L1 instruction). Rather than try to fix each little spot, use the new common memory functions to greatly simplify everything and make sure it is always correct. Signed-off-by: -

The current module section handling code has a lot of verbose statements copied and pasted throughout which makes it pretty hard to digest at a glance. By unifying all of these up front, it is a lot easier to quickly get an idea of what is actually going on. Signed-off-by: -

All kernel modules are required to be built with -mlong-calls and thus should not generate any of these relocations. If they do, it means the module has not been compiled properly, so rather than trying to handle them (and running into random run time errors) just error out on module load to force the module to be compiled correctly.

Now that we have a Blackfin memory function to figure out how to properly access the different regions, drop the custom memory range checks in our ptrace code and use that. It makes the code nicer and fixes bugs where the ptrace logic wasn't handling all the different regions. Signed-off-by: -

Cleanup is performed in two ways: - remove extraneous updates of IPEND[4] w/ CONFIG_IPIPE, and document remaining use. - substitute pop-reg-from-stack instructions with plain SP fixups in all save-RETI-then-discard patterns. Signed-off-by:

The purpose of the EVT14 handler may depend on whether CONFIG_IPIPE is enabled, albeit its implementation can be the same in both cases. When the interrupt pipeline is enabled, EVT14 can be used to raise the core priority level for the running code; when CONFIG_IPIPE is off, EVT14 can be used to lower this level before running softirq handlers. Rename evt14_softirq to evt_evt14 to pick an identifier that fits both, which allows to reuse the same vector setup code as well. Signed-off-by:
