* arch: remove blackfin portArnd Bergmann2018-03-161-115/+0
| | | | | | | | | | | | | | | | | | | The Analog Devices Blackfin port was added in 2007 and was rather active for a while, but all work on it has come to a standstill over time, as Analog have changed their product line-up. Aaron Wu confirmed that the architecture port is no longer relevant, and multiple people suggested removing blackfin independently because of some of its oddities like a non-working SMP port, and the amount of duplication between the chip variants, which cause extra work when doing cross-architecture changes.

* Blackfin: bf526: restrict reboot workaround to 0.0 siliconMike Frysinger2011-07-231-1/+3
| | | | | | | The bug in the BF526 rom when doing a software reset exists only in older silicon versions, so don't clear SWRST on newer parts. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: use on-chip reset func with newer partsMike Frysinger2011-05-251-34/+31
| | | | | | | | Turns out the documentation is wrong and doing "RAISE 1" does not result in a software reset, only a core reset. So when the on-chip rom has a functioning reset helper, use it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
