* ARM: OMAP: DMTimer: Optimize by adding load and startRichard Woodruff2008-07-03
| | | | | | | | | | | | | | | | | | | | | | | | | This patch optimizes the timer load and start sequence. By combining the load and start a needless posted wait can be removed from the system timer execution path. * Before patch register writes are taking up .078% @ 500MHz during idle.

* ARM: OMAP: DMTimer: Use posted modeRichard Woodruff2008-07-03
| | | | | | | | | | | | | | | | This patch adds the use of write posting for the timer. Previously, every write could lock the requestor for almost 3x32KHz cycles. This patch only synchronizes before writes and reads instead of after them and it does it on per register basis. Doing it this way there is some chance to hide some of the sync latency. It also removes some needless reads when non-posted mode is there. With out this fix the read/writes take almost 2% CPU load @500MHz just waiting on tick timer registers. Also define new 34xx only registers. Signed-off-by: Richard Woodruff <r-woodruff2@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

This was presumably done because on those two machines, the PCI(-X) controller (nr == 1) isn't used, requiring initialisation of only the PCIe controller (nr == 0.) However, not initialising the PCI(-X) controller on boards that don't use it leads to a situation where both the PCIe and the PCI(-X) controller think that their root bus is zero, and it messes up IRQ assignment. This patch changes the DNS323 and Kurobox Pro support code to always use nr_controllers == 2.
