Blackfin arch: Fix bug - hardware breakpoint doesn't always work in kgdb · 8a0e9acf

Sonic Zhang authored Nov 18, 2008



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.

Blackfin arch: Cleanup and unify Blackfin IRQ and GPIO IRQ handling · 8d022374

Michael Hennerich authored Nov 18, 2008



 - 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... · 397861cd

Bryan Wu authored Nov 18, 2008

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.
