| * | arm/integrator: Remove unneccessary CONFIG_PCI check.Detlev Zundel2010-04-04-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | pci_eth_init() is already conditional to CONFIG_PCI so not every caller needs to have conditionals. This is the only place in the current code base where such a check is still at the calling site.

| * | at91: use C structs for AT91 OHCI codeMatthias Fuchs2010-04-03-20/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is part of migrating the AT91 support towards using C struct for all SOC access. It removes one more CONFIG_AT91_LEGACY warning. at91_pmc.h needs cleanup after migration of the drivers has been done. Signed-off-by: Matthias Fuchs <matthias.fuchs@esd.eu>

| * | Nomadik: fix reset_timer()Alessandro Rubini2010-04-03-3/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previous code was failing when reading back the timer less than 400us after resetting it. This lead nand operations to incorrectly timeout any now and then. Moreover, writing the load register isn't immediately reflected in the value register. We must wait for a clock edge, so read_timer now waits for the value to change at least once, otherwise nand operation would timeout anyways (though less frequently).

* | 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>
