I think I found another bug in the 36-bit DTS. Looking at U-Boot, I see this:
#ifdef CONFIG_PHYS_64BIT
#define CONFIG_SYS_PCIE2_MEM_BUS 0xe0000000
#define CONFIG_SYS_PCIE2_MEM_PHYS 0xc20000000ull
#else
#define CONFIG_SYS_PCIE2_MEM_BUS 0xa0000000
#define CONFIG_SYS_PCIE2_MEM_PHYS 0xa0000000
#endif
But the 36-bit DTS has this:
pci0: pcie@ffe09000 {
reg = <0x0 0xffe09000 0 0x1000>;
ranges = <0x2000000 0x0 0xa0000000 0xc 0x20000000 0x0 0x20000000
0x1000000 0x0 0x00000000 0xf 0xffc10000 0x0 0x10000>;
I don't think these match. I think the first 'ranges' line should have
0xe0000000 instead of 0xa0000000.
I see the same problem with the other two PCI busses. It looks like the
physical address is correct, but the BUS address is wrong (it's using the
32-bit bus address instead of the 36-bit bus address).
