The boards lock against each other by trying to access the PCI bus before clearing their configuration lock bit. Both boards end up in a loop, sending and receiving "Target Not Ready" messages forever. When running in PCI agent mode, the scanning now takes place after the boards have cleared their configuration lock bit.

The patch is based on Tony Li and Dave Liu work[1]. Though unlike the original patch, by default we don't register PCI-E buses for use in U-Boot, we only configure the controllers for future use in other OSes (Linux). This is done because we don't have enough of spare BATs to map all the PCI-E regions. To actually use PCI-E in U-Boot, users should explicitly define CONFIG_83XX_GENERIC_PCIE_REGISTER_HOSES symbol in the board file. And only then U-Boot will able to access PCI-E, but at the cost of disabled address translation.
