* nios2: Reload timer count in reset_timer()Scott McNutt2010-04-02-0/+33
| | | | | | | | | | | | | | | | | | | When the timestamp is incremented via interrupt and the interrupt period is greater than 1 msec, successive calls to get_timer() can produce inaccurate timing since the interrupts are asynchronous to the timing loop. For example, with an interrupt period of 10 msec two successive calls to get_timer() could indicate an elapsed time of 10 msec after only several hundred usecs -- depending on when the next interrupt actually occurs. This behavior can cause reliability issues with components such as CFI and NAND. This can be remedied by calling reset_timer() prior to establishing the base timestamp with get_timer(0), provided reset_timer() resets the hardware timer (rather than simply resetting only the timestamp). This has the effect of synchronizing the interrupts (and the advance of the timestamp) with the timing loop. Signed-off-by: Scott McNutt <smcnutt@psyent.com>
* nios2: Fix outx/writex parameter order in io.hScott McNutt2010-04-02-8/+8
| | | | | | | | | The outx/writex macros were using writex(addr, val) rather than the standard writex(val, addr), resulting in incompatibilty with architecture independent components. This change set uses standard parameter order. Signed-off-by: Scott McNutt <smcnutt@psyent.com>

* cpu/ non-mpc*: Augment CONFIG_COMMANDS tests with defined(CONFIG_CMD_*).Jon Loeliger2007-07-04-1/+1
| | | | | | | | | | | | | | This is a compatibility step that allows both the older form and the new form to co-exist for a while until the older can be removed entirely. All transformations are of the form: Before: #if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT) After: #if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT) || defined(CONFIG_CMD_AUTOSCRIPT) Signed-off-by: Jon Loeliger <jdl@freescale.com>
