Hello all, I'm using u-boot4 to boot an MPC8266ADS-PCI board, which does so successfully. I have a 4-port USB2.0 hub in one of the pci slots. The problem is twofold. 1. When I download hardhat linux to the board using NFS it seems to override u-boots PCI memory map, and 2. doesn't seem to pick up the Interrupt controller properly as it cannot assign an IRQ to the devices (or I am not assigning the IRQ properly). Does anyone know what I have to do to change the hardhat settings to either - correctly mirror what has been setup in u-boot, or ignore its own settings and simpliy use the existing bootloader configuration. Thanks in advance for any correspondence.
