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:

- This patch adds support for ARCH_WANT_OPTIONAL_GPIOLIB. - It may be changed in future to ARCH_REQUIRE_GPIOLIB. - Change GPIO_BANK_NUM use DIV_ROUND_UP( , ) macro Signed-off-by:

- 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.

Blackfin arch: fix bug - gpio_bank() macros messed up bank number caculating with positioning a gpio The whole story: Before BF51x merged, all the MAX_BLACKFIN_GPIOS are integral multiple of GPIO_BANKSIZE (= 16). But BF51x provides MAX_BLACKFIN_GPIOS = 40 which includes 3 banks and the 3rd bank has only 8 GPIO pins. Therefore, gpio_bank() macros is correct when you try to find a GPIO in which bank (GPIO_35 is in bank 2). But on BF51x gpio_bank(MAX_BLACKFIN_GPIOS) only gives out 2 banks instead of 3 banks for some static array initialization. This patch add a new macros gpio_bank_n() and GPIO_BANK_NUM to do bank number caculating and remain the gpio_bank() macros for positioning a gpio in which bank. Signed-off-by: -

- do not bother generating deprecated /sys files by default now since mdev does not need it - Don't built-in char sport driver and build it as a module in defconfig - disable CONFIG_DEVKMEM by default - enable spi flash driver on boards that have one - switch config to the NAND platfrom driver rather than the bfin async one - do not make BFIN_DMA_5XX optional since a large portion of our code relies on dma functions existing Signed-off-by:
