Since the value of these MMRs aren't changing, store the value in a local variable and work off of that. This avoids multiple MMR reads which are implicitly forced by the volatile markings. Signed-off-by: NMike Frysinger <vapier@gentoo.org>

The BF537 SIC combines the gpio port H mask A interrupts with the emac rx interrupt, so we need to demux this in software. It also combines the gpio port H mask B and the emac tx interrupts, and the watchdog and port F mask B interrupts, but since we don't support mask B yet, just add the defines for now.

The search logic in the gpio demux walks all possible gpio blocks starting at the specified pin. The trouble on bf537 parts when we demux the port F and port G mask A interrupts is that we also demux port H mask A ints. Most of the time this isn't an issue as people don't usually use port H, but might as well avoid it when possible. Signed-off-by: NMike Frysinger <vapier@gentoo.org>

This functionality was merged into the common bfin_pm_standby_ctrl func some time ago, so punt these now unused funcs and data, and localize the wake funcs that aren't needed externally anymore. Signed-off-by: NMike Frysinger <vapier@gentoo.org>

The SIC interrupt line muxing that the bf537 does is specific to this CPU (thankfully), so rip it out of the common code and move it to a bf537-specific file. This tidies up the common code significantly. Signed-off-by: NMike Frysinger <vapier@gentoo.org>

These are only used in a few internal Blackfin places, so move the irq prototypes out of the global header and into the internal irq one. No functional changes other than shuffling locales. Signed-off-by: NMike Frysinger <vapier@gentoo.org>

After some cache setup reordering changesets, the blackfin_cpudata init was left behind. While cpu0's data was correct, cpu1's data was not. Not that big of a deal as these are only used in the cpuinfo output, but should still be fixed. So move the setup of these fields to the common cache setup function to avoid this happening again in the future. Signed-off-by: NMike Frysinger <vapier@gentoo.org>

The smp flush lines are too long and have too many newlines, so scale them back to match the other lines. The %p modifier shows "(null)" for 0, so use %08x instead. Signed-off-by: NMike Frysinger <vapier@gentoo.org>

These files had a lot of whitespace damage, mostly due to copying and pasting original files that had damage. The BF561 header also had a lot of unused CONFIG_DEF_xxx defines, so punt them all. Signed-off-by: NMike Frysinger <vapier@gentoo.org>

Start a new common IRQ header and move all of the CEC pieces there. This lets the individual part headers worry just about its SIC defines. Signed-off-by: NMike Frysinger <vapier@gentoo.org>

Seems the ipipe code just copied & pasted the existing irq lookup logic, so pull the logic out of do_irq() and into a local helper, and convert the two users over to that. Signed-off-by: NMike Frysinger <vapier@gentoo.org>

The local ivg structs need not be exported, so mark them as static. Further, the "num_spurious" variable is only incremented and never actually read anywhere, so punt it. Signed-off-by: NMike Frysinger <vapier@gentoo.org>

Since the on-chip L1 regions are not cacheable, there is no point in trying to flush/invalidate them. Plus, older Blackfin parts like to trigger an exception (like BF533-0.3). Signed-off-by: NSonic Zhang <sonic.zhang@analog.com> Signed-off-by: NMike Frysinger <vapier@gentoo.org>
