What I really don't know is what the first column in the ranges field does. I.e. the <42000000>, <02000000>, and <01000000>.
They are encoding of type of "space" is being described, the first byte's what's important: [42] - prefetchable memory [02] - 32-bit memory space [01] - IO space [00] - CFG space [03] - 64-bit memory space
Here is part of current blob I am using:

}
Here are the U-boot #defines I am using at the moment.
#define CFG_PCI_MEM_BASE 0x80000000
#define CFG_PCI_MEM_PHYS CFG_PCI_MEM_BASE
#define CFG_PCI_MEM_SIZE 0x10000000 /* 256M */
#define CFG_PCI_MMIO_BASE 0x90000000
#define CFG_PCI_MMIO_PHYS CFG_PCI_MMIO_BASE
#define CFG_PCI_MMIO_SIZE 0x10000000 /* 256M */
#define CFG_PCI_IO_BASE 0x00000000
#define CFG_PCI_IO_PHYS 0xF0300000
#define CFG_PCI_IO_SIZE 0x00100000 /* 1M */
Might need to change PCI_IO_BASE to match PCI_IO_PHYS as well?This all looks correct, how are you setting PCILAWBAR0/1, PCILAWAR0/1? - k
