zx_status_t EnableBusMasterUpstream (bool enable)

PCIE roots are already at the top of the topology so there

is no action necessary.

zx_status_t Swizzle (uint dev_id, uint func_id, uint pin, uint * irq)

Perform the swizzle for the root which this swizzle interface applies to.

When legacy IRQs traverse PCI/PCIe roots, they are subject to a platform

specific IRQ swizzle operation. Platforms must supply an implementation

of this method for when they add a root to the bus driver before startup.

dev_id The device ID of the pcie device/bridge to swizzle for.

func_id The function ID of the pcie device/bridge to swizzle for.

pin The pin we want to swizzle

irq An output pointer for what IRQ this pin goes to

ZX_OK if we successfully swizzled

ZX_ERR_NOT_FOUND if we did not know how to swizzle this pin

void PcieRoot (PcieBusDriver & bus_drv, uint mbus_id)

TODO(johngro) : Add support for RCRB (root complex register block) Consider splitting

PcieRoot into PciRoot and PcieRoot (since PciRoots don't have RCRBs)
