I've tested this patch on both -rc1 and yesterday's torvalds/linux.git
with tegra_defconfig: Both with or without this patch I get empty lspci
There doesn't seem to be a tegra/linux.git for-next branch based on -rc1
yet - are patches from other subsystem trees needed to get the on-board
Ethernet detected or maybe some config option?
Or did you test PCIe via the on-board slot?
I used U-Boot v2014.07, in case it matters.
