The previous commit that changed this code to the common GPIO layers forgot to delete the local and now unused "i" variable. Signed-off-by:Mike Frysinger <vapier@gentoo.org>

No code uses these, and the short define names are polluting the global namespace where they collide with things like common irq files. So just punt the damned things. If in the future we need HDMA support, we can make a standalone header for these things. Signed-off-by: -

This patch fixes the Blackfin irqflags to make them I-pipe aware anew, after the introduction of the hard_local_irq_*() API. Signed-off-by:

This patch makes sure to sync the pipeline for the root stage only from the outer interrupt level, when resuming kernel code after an interrupt. This fixes a bug causing EVT15 to be spuriously popped off upon nested interrupts, which in turn would cause the preempted kernel code to resume without supervisor privileges. Signed-off-by:

This patch introduces Blackfin-specific bits to support the current tip of the interrupt pipeline development, mainly: - 2/3-level interrupt maps (sparse IRQs) - generic virq handling - sysinfo v2 format for ipipe_get_sysinfo() Signed-off-by:

Take advantage of more Blackfin-specific insns, and only initialize registers required by the ABI. Signed-off-by: -

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.

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: -

The smp_processor_id() API requires that preempt be disabled when calling it, so make sure it is when we go to send messages to other processors. Signed-off-by:

The BF54x lacks dedicated DMA channels for the UART peripherals and need to be muxed between others. So add a kconfig option so people can select which channels the UARTs will use so they can pick between SPORTs and the less commonly used EPPI/PIXC peripherals. Signed-off-by:
