2008-06-22[ARM] Orion: PCIe x4/x1 detection supportLennert Buytenhek
The Discovery Duo (MV78xx0) has two x4 PCIe ports which can either be used in x4 mode or in quad x1 mode. This patch adds an accessor function to the generic plat-orion PCIe handling code to detect in which of the two modes we're running (which is determined by strap pins and/or configured by the bootloader).

2008-06-22[ARM] Orion: add a separate BRIDGE_INT_TIMER1_CLR defineKe Wei
Some Feroceon-based SoCs have an MBUS bridge interrupt controller that requires writing a one instead of a zero to clear edge interrupt sources such as timer expiry. This patch adds a new BRIDGE_INT_TIMER1_CLR define, which platform code can set to either ~BRIDGE_INT_TIMER1 (write-zero-to-clear) or BRIDGE_INT_TIMER1 (write-one-to-clear) depending on the platform.

2008-06-22[ARM] Orion: top-level IRQs are level-triggeredLennert Buytenhek
Make it clear that Orion top-level IRQs are level-triggered. This means that we don't need an ->ack() handler, or at least, we don't need the ->ack() handler (or the acking part of the ->mask_ack() handler) to actually do anything. Given that, we might as well point our ->mask_ack() handler at the ->mask() handler instead of providing a dummy ->ack() handler, since providing a ->mask_ack() handler on level IRQ sources will prevent ->ack() from ever being called.
