2008-11-18Blackfin arch: Fix bug - hardware breakpoint doesn't always work in kgdbSonic Zhang
Hardware breakpoint doesn't always work in kgdb. It works at the first two times, but if you repeatedly trigger that hardware breakpoint, it would slip over that point once in two times. Fix it by always setting hw bp skip to 0. gdb does skip after hw bp trap. Signed-off-by: Sonic Zhang <sonic.zhang@analog.com> Signed-off-by: Bryan Wu <cooloney@kernel.org>

2008-11-18Blackfin arch: Cleanup and unify Blackfin IRQ and GPIO IRQ handlingMichael Hennerich
- Remove SSYNC() - Use irq_to_gpio where applicable - Remove gpio_edge_triggered bitfield, check irq_desc fields instead. - Remove gpio_both_edge_triggeredb bitfield, check irq_desc fields instead. - Use BITMAP and bitops on gpio_enabled - Preferably use 32-bit - Looking at the disassembly this indeed saves quite a few instructions.
