This moves an entire board to use a live device tree as an example of the impact.
Nyan-big was chosen because I can easily and boot U-Boot without any media swapping, etc. Beaver is enabled as well since it failed to boot with serial v1 due to a disabled console node.
Have you been able to test this v2 series? Some problems were reported with v1 and I have found a few more since I discovered my jetson- tk1 board. I'm planning to send a v3 soon, but please let me know if you see any issues.
One more note - I pushed a v3 series to u-boot-dm/livet-working but have not sent the patches. Let me know if you find anything.
While Apalis TK1 now at least boots without any GPIO driver issues I still saw the following few glitches:
Apalis TK1 # gpio status -a Bank A: A0: func A1: input: 1 [ ] A2: func ... FF7: func
Bank as3722_: as3722_0: unknown as3722_1: unknown as3722_2: unknown as3722_3: unknown as3722_4: unknown as3722_5: unknown as3722_6: unknown as3722_7: unknown

While PCIe enumeration does not error out it seems not to detect the Ethernet chip:
Apalis TK1 # pci enum Apalis TK1 # dm tree Class Probed Name
root [ + ] root_driver pci [ + ] |-- pcie-controller@01003000 ...
That's how it should look (e.g. with older working U-Boot):
Apalis TK1 # ver

After enabling CONFIG_OF_LIVE I noticed the following additional issue:
Apalis TK1 # pci enum ERROR: tegra-pcie: resource "pads" not found at u-boot.git/drivers/pci/pci_tegra.c:499/tegra_pcie_parse_dt()
OK that sounds like a new problem, I'll take a look.
Trying to use a vanilla mainline Linux kernel device tree also did not help:
U-Boot 2017.07-rc1-00150-gf325a89-dirty (Jun 09 2017 - 14:33:21 +0200)

This should be fixed by u-boot-dm/livet-working - can you please check you have the latest version?
Just the order of the SDHCI controllers changed:
Apalis TK1 # mmc dev 2; mmc info tegra_mmc_send_cmd_bounced: MMC Timeout Interrupt status 0x00000001 Interrupt status enable 0xffff003b Interrupt signal enable 0xffff0002 Present status 0x01fb02f6 mmc_init: -1, time 8066
It could be this:
http://patchwork.ozlabs.org/patch/772771/
So the ordering has changed?
But PCIe enumeration still fails:
Apalis TK1 # pci enum ERROR: tegra-pcie: resource "pads" not found at /run/media/zim/Build/Sources/u- boot.git/drivers/pci/pci_tegra.c:499/tegra_pcie_parse_dt()
Let me know should you require any additional information.
Much appreciated.
As above can you please confirm the git hash you tested?
I found the tegra's PCI was not ported to livetree and also there was a bug in the PCI uclass (which suggests that the PCI test coverage is not so great).
I've pushed a new version to u-boot-dm/livet-working and will send v3 patches if they pass buildman.
My tegra-TK1 PCI does not work. I think it is because I accidentally corrupted the PMIC register values at one point. Is there a way to restore it?
