* 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>

* Correct ARM Versatile Timer InitializationGururaja Hebbar K R2008-08-25-4/+35
| | | | | | | | | | | | | | | - According to ARM Dual-Timer Module (SP804) TRM (ARM DDI0271), -- Timer Value Register @ TIMER Base + 4 is Read-only. -- Prescale Value (Bits 3-2 of TIMER Control register) can only be one of 00,01,10. 11 is undefined. -- CFG_HZ for Versatile board is set to #define CFG_HZ (1000000 / 256) So Prescale bits is set to indicate - 8 Stages of Prescale, Clock divided by 256 - The Timer Control Register has one Undefined/Shouldn't Use Bit So we should do read/modify/write Operation Signed-off-by: Gururaja Hebbar <gururajakr@sanyo.co.in>
