* Generic udelay() with watchdog supportIngo van Lil2009-12-05-1/+1
| | | | | | | | | | | | | According to the PPC reference implementation the udelay() function is responsible for resetting the watchdog timer as frequently as needed. Most other architectures do not meet that requirement, so long-running operations might result in a watchdog reset. This patch adds a generic udelay() function which takes care of resetting the watchdog before calling an architecture-specific __udelay(). Signed-off-by: Ingo van Lil <inguin@gmx.de>

* Fix sc520 timer interrupt generationGraeme Russ2009-09-04-3/+3
| | | | | | | | The current implementation has the timer being started before the interrupt handler is installed. It the interrupt occurs before the handler is installed, the timer interrupt is never reset and the timer stops Signed-off-by: Graeme Russ <graeme.russ@gmail.com>

* Factor out SC520 sub-featuresGraeme Russ2009-03-20-0/+73
Moved sub-features of the SC520 code which is currently selectively compiled using #ifdef out of sc520.c into individual files selectively compiled via the makefile Signed-off-by: Graeme Russ <graeme.russ at gmail.com>
