• ede6f5aea   Fix up 64-bit byte swaps for most 32-bit architectures ... Browse Code »

  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.

• 8d0223744   Blackfin arch: Cleanup and unify Blackfin IRQ and GPIO IRQ handling ... Browse Code »

  - 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.

• 397861cd8   Blackfin arch: fix bug - gpio_bank() macros messed up bank number caculating with positioning a gpio ... Browse Code »

  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.
