[PATCH] ARM: tegra_defconfig: enable CONFIG_ARM_APPENDED_DTB

[PATCH] ARM: tegra_defconfig: enable CONFIG_ARM_APPENDED_DTB

[Olof Johansson]

This is needed on TrimSlice, since the u-boot on that hardware is too old
to support native device tree booting. Same for any device that currently
run fastboot, but none of that hardware is supported in mainline today;
or at least there are modern u-boot ports for it.

CompuLab provide a u-boot that supports dtb, and afaik, it's supported
in mainline u-boot as well.

They do? The hardware I have came with a very old u-boot. Got a link
to the newer one?

Mainline U-Boot runs nicely on the TrimSlice. Missing functionality
includes PCIe Ethernet and HDMI, but everything else works fine IIRC.
You can flash it using:

https://github.com/NVIDIA/tegra-uboot-flasher-scripts

(read README-developer.txt first, then README-user.txt)

Oh great. Unfortunately lack of PCI-e makes it hard to network boot
(unless I add a redundant usb-ethernet adapter on it). Hmm.

I think Thierry was looking into PCIe, although I don't think it's
working yet. I always just use USB even on TrimSlice since it's easier
to move the USB connector than the network connector when switching
machines:-) PCIe works in Linux now though, as of v3.12-rc1.

I have a local branch that makes it work at least on Beaver, but it
causes the kernel PCIe to fail for reasons that I haven't tracked down
yet.
