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.

- 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:

The original code defined _exception_stack but not alloc space for the exception stack. In exception, this area is over written by exception stack. Common kernel luckly boot up, but SMP kernel stuck. Signed-off-by:

The __SWAB_64_THRU_32__ case of a 64-bit byte swap was depending on the no-longer-existant ___swab32() method (three underscores). We got rid of some of the worst indirection and complexity, and now it should just use the 32-bit swab function that was defined right above it. Reported-and-tested-by:
