* Blackfin arch: fix bug - crashes in tcp_v4_send_resetBernd Schmidt2009-01-071-1/+2
| | | | | | | | | | Michael says that some bugs are crashes in tcp_v4_send_reset. There's a missing clobber of "CC" in our checksum assembly statement; fixing this makes the generated code look much saner.

* Blackfin arch: fix bug - gpio_bank() macros messed up bank number caculating ↵Bryan Wu2008-11-181-0/+2
| | | | | | | | | | | | | | | | | | | | 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.
