This target is used for running U-Boot on top of Coreboot. In

this case Coreboot does the early inititalisation, and U-Boot

U-Boot is loaded as a fallback payload from Coreboot, in

This is the memory-mapped address of PCI configuration space, which

|
is only available through the Enhanced Configuration Access
|

Mechanism (ECAM) with PCI Express. It can be set up almost

anywhere. Before it is set up, it is possible to access PCI
|
|

configuration space through I/O access, but memory access is more
|
|
|
|
convenient. Using this, PCI can be scanned and configured. This
|
|
|
|
should be set to a region that does not conflict with memory
|
|
|
|
assigned to PCI devices - i.e. the memory and prefetch regions, as
|
|
|
|
passed to pci_set_region().
