[U-Boot] i.mx6q PCIE

Hi folks,

I'm attempting to bring up a custom board with an i.mx6q on it.

I've added support for PCIe and E1000 ethernet, and the PCI bus scans,
showing my card (Intel i210 chip)

The E1000 driver bombs out during init, however.

I've tried inserting code to repeatedly read the BAR for 4k (and print a
".") after bus mastering is enabled, and this manages about 70 cycles
before I no longer see serial output.

if I reset the board, I may or may not get any "." printed, and
sometimes I get completely other characters printed (perhaps serial is
losing sync?).

Anyone have any ideas ?
