MIPS: GIC: Fix GICBIS macro The GICBIS macro could update the GIC registers incorrectly, depending on the data value passed in: * Bits were only OR'd into the register data, so register fields could not be cleared. * Bits were OR'd into the register data without masking the data to the correct field width, corrupting adjacent bits.

MIPS: GIC: Generalise check for pending interrupts Move most of the functionality of gic_get_int() into a new function gic_get_int_mask() which takes a bitmask of interrupts in which the caller is interested, and returns the subset which are pending for the current CPU. This allows CP0 IRQ dispatch routines to check only the GIC interrupts which are routed to a particular CPU interrupt input. gic_get_int() is reimplemented using gic_get_int_mask() and is retained for use by any platforms for which gic_get_int() is sufficient.

MIPS: GIC: Remove GIC_FLAG_IPI irq-gic.c:gic_get_int() masks out interrupts from the pending set which aren’t in the pcpu_mask. Only interrupts marked with GIC_FLAG_IPI were set in pcpu_mask, meaning that peripheral interrupts also had to be marked as IPIs. Remove the use of GIC_FLAG_IPI and allow the flags member of struct gic_intr_map to be zero.

MIPS: GIC: Move GIC_NUM_INTRS into platform irq.h The value of GIC_NUM_INTRS is platform-specific. Using a default value from gic.h will result in incorrect behaviour on some systems, so require a suitable definition to be present in the platform's irq.h.

MIPS: allow GIC clockevent device config from other CPUs This patch allows the GIC clockevent device for a CPU to be configured by another CPU. This makes GIC clockevent devices suitable for use as the tick broadcast device, where formerly the GIC timer local to the configuring CPU would have been configured incorrectly.

Below is a list of the various changes. * No longer select CSRC_GIC by default for Malta platform. * Limit choice for either the GIC or R4K clocksource, not both. * Change location in Makefile. * Created new 'gic_read_count' function in common 'irq-gic.c' file. * Change 'git_hpt_read' function in 'csrc-gic.c' to use new function. * Surround GIC specific code in Malta platform code with #ifdef's. * Only initialize the GIC clocksource if it was selected. Original code called it unconditionally if a GIC was found. Signed-off-by: Steven J. Hill <Steven.Hill@imgtec.com>
