[MIPS] Misc fixes for plat_irq_dispatch functions

2007-03-19T20:22:43Z

o adds missing ST0_IM masks, which caused the logging of valid interrupts as spurious o stops pnx8550 to log every interrupt as spurious o adds cause register masks for ip22/ip32, which caused handling of masked interrupts o removes some superfluous parentheses in the SNI interrupt code Signed-Off-By: Thiemo Seufer Signed-off-by: Ralf Baechle

[MIPS] Kill redundant EXTRA_AFLAGS

2007-02-26T23:06:05Z

Many Makefiles in arch/mips have EXTRA_AFLAGS := $(CFLAGS) line. This is redundant while AFLAGS contains $(cflags-y) and any options only listed in CFLAGS (not in cflags-y) should be unnecessary for asm sources. Signed-off-by: Atsushi Nemoto Signed-off-by: Ralf Baechle

[MIPS] use name instead of typename for each irq_chip

2007-02-06T16:53:14Z

The "typename" field was obsoleted by the "name" field. Signed-off-by: Atsushi Nemoto Signed-off-by: Ralf Baechle

[MIPS] prom_free_prom_memory cleanup

2007-02-06T16:53:09Z

Current prom_free_prom_memory() implementations are almost same as free_init_pages(), or no-op. Make free_init_pages() extern (again) and make prom_free_prom_memory() use it. Signed-off-by: Atsushi Nemoto Signed-off-by: Ralf Baechle

[MIPS] Make I8259A_IRQ_BASE customizable

2007-02-06T16:53:09Z

Move I8259A_IRQ_BASE from asm/i8259.h to asm/mach-generic/irq.h and make it really customizable. And remove I8259_IRQ_BASE declared on some platforms. Currently only NEC_CMBVR4133 is using custom I8259A_IRQ_BASE value. Signed-off-by: Atsushi Nemoto Signed-off-by: Ralf Baechle

[MIPS] Define MIPS_CPU_IRQ_BASE in generic header

2007-02-06T16:53:08Z

The irq_base for {mips,rm7k,rm9k}_cpu_irq_init() are constant on all platforms and are same value on most platforms (0 or 16, depends on CONFIG_I8259). Define them in asm-mips/mach-generic/irq.h and make them customizable. This will save a few cycle on each CPU interrupt. A good side effect is removing some dependencies to MALTA in generic SMTC code. Although MIPS_CPU_IRQ_BASE is customizable, this patch changes irq mappings on DDB5477, EMMA2RH and MIPS_SIM, since really customizing them might cause some header dependency problem and there seems no good reason to customize it. So currently only VR41XX is using custom MIPS_CPU_IRQ_BASE value, which is 0 regardless of CONFIG_I8259. Testing this patch on those platforms is greatly appreciated. Thank you.

[MIPS] IRQ cleanups

2006-11-30T01:14:46Z

This is a big irq cleanup patch. * Use set_irq_chip() to register irq_chip. * Initialize .mask, .unmask, .mask_ack field. Functions for these method are already exist in most case. * Do not initialize .startup, .shutdown, .enable, .disable fields if default routines provided by irq_chip_set_defaults() were suitable. * Remove redundant irq_desc initializations. * Remove unnecessary local_irq_save/local_irq_restore, spin_lock. With this cleanup, it would be easy to switch to slightly lightwait irq flow handlers (handle_level_irq(), etc.) instead of __do_IRQ(). Though whole this patch is quite large, changes in each irq_chip are not quite simple. Please review and test on your platform. Thanks. Signed-off-by: Atsushi Nemoto Signed-off-by: Ralf Baechle
